Problem with substring or println

Hi,
I have the following code, and it basically is looking for text between <title></title> tags. I use substring to grab the code between the two tags, and debugging shows it is correct. However, when I output it, my code stops and I just have whitespace.
Any suggestions?
while(((str = in.readLine()) != null) && (found == false))
     if(str.indexOf("<title>") != -1) // Title exists
          found = true;
          int titlestart=0;
          int titleend=0;
          titlestart = str.indexOf("<title>");
          titleend = str.indexOf("</title>");
          title=str.substring(titlestart,titleend);
          out.println("Found:" + title +" Start index at:" + titlestart + " End at:"+titleend );
}

The code below works for
1. <title>foo<title>
2. <title>
foo
</title>
3. <title>foo
bar</title>
Use it if it helps...
            StringBuffer title = new StringBuffer();
            while (((str = in.readLine()) != null) && found == false)
                // start reading
                if (str.indexOf("<title>") != -1) // Title exists
                    boolean singleLine = false;
                    found = true;
                    if (str.indexOf("</title>") == -1)
                        //data between title tags span multilines.
                        //And yet there may be some data on this line eg, <title>foo...
                        title.append(str.substring(str.indexOf("<title>") + 7, str.length()));
                    else
                        //tag starts and ends in a single line
                        title.append(str.substring(str.indexOf("<title>") + 7, str.indexOf("</title")));
                        singleLine = true;
                    if(!singleLine)
                        do
                            str = in.readLine();
                            if (str.indexOf("</title>") == -1)
                                //if the tag doesnt end, keep on reading
                                title.append(str);
                            else
                                //if the tag ends on this line, egt all data that may be present before tag end
                                //eg ...bar</title>
                                title.append(str.substring(0, str.indexOf("</title>")));
                        while (str != null && str.indexOf("</title>") == -1);
            out.println(title);ram.

Problem with substring in xsl file?

Hallo,
i have a xsl file, when using
<xsl:value-of select="StsEdat"/> i've got 2007-05-21, that's o.k.
when using <xsl:value-of select="substring(StsEdat,9,2)"/> the answer is blank.
also 0,5 or so on. substring at this position delivers blank. why?
what can it be? i'am helpless.
any help is appreciated.

Hi,
I used <xsl:value-of select="substring(StartDate,9,2)"/> the answer was 21 and to 0,5 the answer was 2007. It seems that's ok!
Try to do it and see if you have problem with substring.
<xsl:variable name="StsEdat">2007-05-21</xsl:variable>
<xsl:value-of select="substring($StsEdat,9,2)"/>
or this weird way, :)
<xsl:variable name="StsEdat">2007-05-21</xsl:variable>
<xsl:value-of select='substring-after(substring-after($StsEdat, "-"), "-")' />

Problem with SUBSTR

En una view, al crear un campo con SUBSTR( campo, 1, 150), devuelve un campo con tamaño de 600, el correcto seria 150, cual es la causa ?

Hi user 512674,
Please, post your questions in English. Otherwise, only Spanish-speaking people can help you (or those who can guess what the problem is ;)
SUBSTR(campo, 1, 150) means 150 characters. In an AL32UTF8 database, which you most probably have, this translates to 4*150=600 bytes. That is, the column must be able to store 600 bytes to be sure that it can store 150 AL32UTF8 character codes.
View creation does not depend on the value of the session parameter NLS_LENGTH_SEMANTICS. The view columns inherit the semantics from the underlying table columns. If <campo> column is defined with character semantics the view column will be created with character semantics: ALL_TAB_COLUMNS.DATA_LENGTH will show 600 (bytes), ALL_TAB_COLUMNS.CHAR_LENGTH will show 150 (characters), ALL_TAB_COLUMNS.CHAR_USED will show 'C'. Otherwise, the view will be created with byte semantics: ALL_TAB_COLUMNS.DATA_LENGTH will show 600 (bytes), ALL_TAB_COLUMNS.CHAR_LENGTH will show 600 (characters), ALL_TAB_COLUMNS.CHAR_USED will show 'B'.

Problem with Substring

Here's my code..
String Varble = rs0.getString("adddate").substring(0,10);
out.println("<td>" + stmt + "</td>");
I've also tried this (which is the same thing just more code) Now it DOES work if I make tinydate text.
String tinydate = rs0.getString("adddate")
String Varble = tinydate.substring(0,10);
out.println("<td>" + stmt + "</td>");
Here's the Error. What am I doing wrong?
javax.servlet.ServletException: Error: Browse.jsp - select adddate from K9Manager WHERE adddate is not NULL failed.java.sql.SQLException: [TDS Driver]No current row[TDS Driver]No current row

Hard to tell what you are doing wrong, but it is nothing to do with the substring method. The message "No current row" suggests to me that you haven't called rs0.next() to move to the first row of the result set, but the error message displays your SQL, which I find strange. But maybe that's just how your JDBC driver does things.

Problem with SUBSTR and GROUP BY

Hi people...
I'm needing a little help with this case. I'm executing this SQL and got error ORA-01722. I've tried to use number columns, alias and the syntax below and always got error. My problem is the SUBSTR, without it I can run the SQL with no error.

Problems with System.out.println()

I tried writing a simple 'Hello world'-program:
public class Test{
     public static void main(String[] args){
          System.out.println("Hello World!");
     }//main()
}//Test
But the text wouldn't appear in the DOS-window. The only text that showed up was the standard 'Press any key to close the window'. The program compiled without any problems, but didn't work when I tried to run it.
Does anyone have any idea what's wrong?

Are u sure , the main() class part is donecorrectly.
Becuse program will compile but not run without a
main() class.what do you mean by main() class???First of all main() is a method, not a class. The main() method the JRE recognizes and runs is the:
public static void main(String[] params)
If you don�t have exaclty those modifiers and receive an array of Strings parameter it will send you an runtime exception.
Your code compiles and runs fine, the problem isn�t really System.out.print() it is something with your configuration.
I have to rename the class to TestF. Here is the running:
C:\cJava>javac TestF.java
C:\cJava>java TestF
Hello World!

Out.println() problems with large amount of data in jsp page

I have this kind of code in my jsp page:
out.clearBuffer();
out.println(myText); // size of myText is about 300 kbThe problem is that I manage to print the whole text only sometimes. Very often happens such that the receiving page gets only the first 40 kb and then the printing stops.
I have made such tests that I split the myText to smaller parts and out.print() them one by one:
Vector texts = splitTextToSmallerParts(myText);
for(int i = 0; i < texts.size(); i++) {
out.print(text.get(i));
out.flush();
}This produces the same kind of result. Sometimes all parts are printed but mostly only the first parts.
I have tried to increase the buffer size but neither that makes the printing reliable. Also I have tried with autoFlush="false" so that I flush before the buffer size gets overflowed; again same result, sometimes works sometimes don't.
Originally I use such a system where Visual Basic in Excel calls a jsp page. However, I don't think that this matters since the same problems occur if I use a browser.
If anyone knows something about problems with large jsp pages, I would appreciate that.

Well, there are many ways you could do this, but it depends on what you are looking for.
For instance, generating an Excel Spreadsheet could be quite easy:
import javax.servlet.*;
import javax.servlet.http.*;
import java.io.*;
public class TableTest extends HttpServlet{
     public void doGet(HttpServletRequest request, HttpServletResponse response) throws IOException, ServletException {
          response.setContentType("application/xls");
          PrintWriter out = new PrintWriter(response.getOutputStream());
                out.println("Col1\tCol2\tCol3\tCol4");
                out.println("1\t2\t3\t4");
                out.println("3\t1\t5\t7");
                out.println("2\t9\t3\t3");
          out.flush();
          out.close();
}Just try this simple code, it works just fine... I used the same approach to generate a report of 30000 rows and 40 cols (more or less 5MB), so it should do the job for you.

Problem with conversion of strings like THISStr - this_str capitalization

Problems with WLST embedded in java app.

Hi,
I have a problem with the WLST embedded in a java app.
I want to programatically create or reconfigure a domain from a java application. Following is a simple example of what I want to do.
import weblogic.management.scripting.utils.WLSTInterpreter;
public class DomainTester {
static WLSTInterpreter interpreter = new WLSTInterpreter();
private void processDomain() {
    if(domainExists()) {
      System.out.println("Should now UPDATE the domain");
    } else {
      System.out.println("Should now CREATE the domain");
private boolean domainExists() {
    try {
      interpreter.exec("readDomain('d:/myDomains/newDomain')");
      return true;
    }catch(Exception e) {
      return false;
}The output of this should be one of two possibles.
1. If the domain exists already it should output
"Should now UPDATE the domain"
2. If the domain does not exist it should output
"Should now CREATE the domain"
However, if the domain does not exist the output is always :
Error: readDomain() failed. Do dumpStack() to see details.
Should now UPDATE the domain
It never returns false from the domainExists() method therefor always states that the exec() worked.
It seams that the exec() method does not throw ANY exceptions from the WLST commands. The catch clause is never executed and the return value from domainExists() is always true.
None of the VERY limited number of examples using embedded WLST in java has exception or error handling in so I need to know what is the policy to detect failures in a WLST command executed in java??? i.e. How does my java application know when a command succeeds or not??
Regards
Steve

Hi,
I did some creative wrapping for the WLSTInterpreter and I now have very good programatic access to the WLST python commands.
I will put this on dev2dev somewhere and release it into the open source community.
Don't know the best place to put it yet, so if anybody sees this and has any good ideas please feel free to pass them on.
Here is the wrapper class. It can be used as a direct replacement for the weblogic WLSTInterpreter. As I can't overload the actual exec() calls because I want to return a String from this call I created an exec1(String command) that will return a String and throw my WLSTException which is a RuntimeException which you can handle if you like.
It sets up stderr and stdout streams to interpret the results both from the Python interpreter level and at the JVM level where dumpStack() just seem to do a printStackTrace(). It also calls the dumpStack() command should the result contain this in its text. If either an exception is thrown from the lower level interpreter or dumpStack() is in the response I throw my WLSTException containing this information.
package eu.medsea.WLST;
import java.io.ByteArrayOutputStream;

          baosOut.reset();
          StringBuffer buf = new StringBuffer("");
          if (err.length() != 0) {
               buf.append(err);
          if (out.length() != 0) {
               buf.append(out);
          return buf.toString();
     // Utility to remove the end of line sequences from the result if any.
     // Many of the response are terminated with either \r or \n or both and
     // some responses can contain more than one of them i.e. \n\r\n
     private String stripCRLF(String line) {
          if(line == null || line.length() == 0) {
               return line;
          int offset = line.length();
          while(true && offset > 0) {
               char c = line.charAt(offset-1);
               // Check other EOL terminators here
               if(c == '\r' || c == '\n') {
                    offset--;
               } else {
                    break;
          return line.substring(0, offset);
}Next here is the WLSTException class
package eu.medsea.WLST;
public class WLSTException extends RuntimeException {
     private static final long serialVersionUID = 1102103857178387601L;
     public WLSTException() {
          super();
     public WLSTException(String message) {
          super(message);
     public WLSTException(Throwable t) {
          super(t);
     public WLSTException(String s, Throwable t) {
          super(s, t);
}And here is the start of a wrapper class for so that you can use the WLST commands directly. I will flesh this out later with proper var arg capabilities as well as create a whole Exception hierarchy that better suites the calls.
package eu.medsea.WLST;
// Provides methods for the WLSTInterpreter
// just to make life a little easier.
// Also provides access to the more generic exec(...) call
public class WLSTCommands {
     public void cd(String path) {

     public void edit() {
          exec("edit()");

     // The generic wrapper for the interpreter exec() call
     public String exec(String command) {
          return interpreter.exec1(command);
     private WLSTInterpreterWrapper interpreter = new WLSTInterpreterWrapper();
}Lastly here is some example code using these classes:
its using both the exec(...) and cd(...) wrapper commands from the WLSTCommand.class shown above.
    String machineName = ...; // get name from somewhere
    try {
     exec("machine=create('" + machineName + "','Machine')");
     cd("/Machines/" + machineName + "/NodeManager/" + machineName);
     exec("set('ListenAddress','10.42.60.232')");
     exec("set('ListenPort', 5557)");
    }catch(WLSTException e) {
        // Possibly the machine object already exists so
        // lets just try to look it up.
     exec("machine=lookup('" + machineName + "','Machine')");
...After this call a machine object is setup that can be allocated later like so:
     exec("set('Machine',machine)");Regards

Problems with Java DOM Mapping

Hi Experts,
as part of my diploma-thesis I have to write a java DOM-Mapping, which mapps the following incoming message:
<mt_MappingOUT>
<set>
<set_Element_01>...</set_Element_01>
<set_Element_02>... </set_Element_02>
<set_Element_03>... </set_Element_02>
<set_Element_10> </set_Element_10>
</set>
</mt_MappingOUT>
to the following outgoinig message:
<mt_MappingIN>
<TABLE>
<item>
<item_FIELD_01> </item_FIELD_01>
<item_FIELD_10> <item_FIELD_10>
<i/tem>
</TABLE>
</mt_MappingIN>
I am not a very experienced Java-Developer. You can see my code down there, which I tried to implement according to some bloggs; unfortunately the result is not what I want to have

Little problem with Strings.

          I have an little problem with Strings, i make one comparision like this.
          String nombre="Javier";
          if( nombre.equalsIgnoreCase(output.getStringValue("CN_NOMBRESf",null)) )
          Wich output.getStringValue("CN_NOMBRESf",null) is "Javier" too, because I display
          this before and are equals.
          What I do wrong?.


You are actually making your users key in things like
"\026"? Not very user-friendly, I would say. But
assuming that is the best way for you to get your
input, or if it's just you doing the input, the way to
change that 4-character string into the single
character that Java represents by '\026', you would
use a bit of code like this:char encoded =
(char)Integer.parseInt(substring(inputString, 1),
16);
DrClap has the right idea, except '\026' is octal, not hex. So change the radix from 16 to 8. Unicode is usually represented like '\u002A'. So it looks like you want:String s = "\\077";
System.out.println((char)Integer.parseInt(s.substring(1), 8));Now all you have to do is parse through the String and replace them, which I think shouldn't be too hard for you now :)

Problem with traverse method

Hi, I am having this problem:
I made a CustomItem, a TextField, now I overloaded the traverse method, so if the keycode is Canvas.UP or Canvas.DOWN then return false else return true.
The problem is that when I press the left or rigth button it also returns false and not true.
and there is another problem with traverse, before returning false or true I set a boolean and call to repaint to draw it on some way if its selected or not, the paint method is being called but it just dont draw as desired.
protected void paint(Graphics g, int ancho, int alto) {
          System.out.println ("Dentro del paint, seleccionado="+seleccionado);
          try {
               g.drawString(label, 0, 0, Graphics.TOP|Graphics.LEFT);
               if (!seleccionado) {
                    g.setColor(120, 120, 120);
               g.drawRect(0, 4, tama�oTexto+8, 25);
               if (seleccionado) {
                    g.setColor(255, 255, 255);
                    g.fillRect(1, 5, (tama�oTexto+8-1), 23);
               g.setColor(0, 0, 0);
               if (!seleccionado) {
                    g.setColor(80, 80, 80);
               g.drawString(texto, 4, 7, Graphics.TOP|Graphics.LEFT);
               if (seleccionado) {
                    int cursorX=Font.getDefaultFont().charsWidth((texto.substring(0, idLetraActual)).toCharArray(), 0, texto.substring(0, idLetraActual).length())+4;
                    g.drawChar('|', cursorX, 7, Graphics.TOP|Graphics.LEFT);
          } catch (Exception E){
               E.printStackTrace();
     }the traverse method set the seleccionado variable and calls to repaint but instead of being false the paint method is drawing it as true (most of times).

I have a problem with findByxxx() method.. in
Container managed bean.
i have
Collection collection =
home.findByOwnerName("fieldValue");
specified in my Client Program, where ownerName is the
cmp fieldname..
and
public Collection findByOwnerName(String ownerName)
throws RemoteException, FinderException
defined in my home interface.
i have not mentioned the findBy() method anywhere else
(Bean class). You have to describe the query in the deployment descriptor.
>
Even if i have a same "fieldValue" in the database
(Oracle), which i specified in findBy() method, iam a
result of owner Not found, which is not the case as i
have that owner name.
for the same application if i use findByPrimaryKey(),
it is working..
Can any one please post me the solution.

Problem with SP with table parameters

Hello, I have problem with stored procedure with paramater which is table type.
I have defined my own type
CREATE OR REPLACE TYPE STRING_LST AS TABLE OF VARCHAR2(80);
and i have stored procedure like this
PROCEDURE probe(outList OUT STRING_LST) IS BEGIN outList := STRING_LST(); outList.EXTEND(); outList(outList.LAST) := 'ONE'; outList.EXTEND(); outList(outList.LAST) := 'TWO'; outList.EXTEND(); outList(outList.LAST) := 'THREE'; END probe;
I have java class which connects to the database and calls this procedure
package mypackage; import java.sql.CallableStatement; import java.sql.Connection; import java.sql.DriverManager; import java.sql.SQLException; import java.sql.Types; import java.sql.Array; public class DAO_Test { public static String toNormalString (String aa) { if (aa != null && aa.startsWith("0x")) { StringBuffer str = new StringBuffer(64); for (int i = 2; i < aa.length(); i += 2) { str.append((char) Integer.parseInt(aa.substring(i, i + 2), 16)); } return str.toString(); } else { return aa; } } public void probe ( ) { try { DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver()); Connection conn = DriverManager.getConnection("dbc:oracle:thin:@server_ip:database_name", "sa", "blahblah"); String sql = "{ CALL PROBE(?) }"; String sqlType = "STRING_LST"; CallableStatement cs = conn.prepareCall(sql); cs.registerOutParameter(1, Types.ARRAY, sqlType); cs.execute(); Array arr = cs.getArray(1); String[] values = (String[]) arr.getArray(); for (int i = 0; i < values.length; i++) { System.out.println("" + i + ": '" + toNormalString(values) + "'");
cs.close();
conn.close();
} catch (SQLException e) {
logger.error("SQLException", e);
} catch (Exception e) {
logger.error("Exception", e);
public static void main (String args[]) throws SQLException {
DAO_Test test = new DAO_Test();
test.probe();
Now...
When I run this class on my local machine the result is OK nad looks like
1: 'ONE'
2: 'TWO'
3: 'THREE'
But when I copy this class on the server and run it, the result is wrong
1: '???'
2: '???'
3: '???'
Here is my environment:
on local machine
eclipse 3.3.1
java 1.5 (java version compiler in eclipse is 1.4)
on server
oracle 9.2.0.6.0
java 1.4.2_08
Result from table parameters are always 3 question marks :|
What is the problem?

HI,
I think i found the solution: nls_charset12.jar from page
http://www.oracle.com/technology/software/tech/java/sqlj_jdbc/htdocs/jdbc9201.html
I have copied this jar to server lib directory and it works fine :)

URGENT timout problems with bc4j

Hello Jdev Team,
We have a serious problem with the BC4J. The situation is as
follows:
We use BC4J with jsp pages an run the whole thing on a j2ee
Container.
We have written our own ApplicationPool class and
ApplicationModule datatag because the users have to login
using different credentials. The login users are db-users. The
application release mode is reserved.
The application crashes frequently. 2 errors occur.
First of all we get an JBO-30003: "The application pool, {AM
Name}, failed to checkout an application module instance."
after the BC4J Container timeout --> messages ("BC4J HTTP
Container was timed out" and "The binding listener for { AM
name} was timed out")
We haven't found a way to alter the BC4J container timeout.
Where do we customize the timeout?
We have tried to use the HttpSessionTimeOut variable but it
seems to have no effect.
I hope you can help us with this one.
Second problem is that the J2EE Container stops functioning
after a couple of requests.
Even if an other browser is started (on the same or different
machine) the Container does not respond to any request.
We have found a Thread on technet handling this kind of problem
but the solution doesn't work in our case.
(the solution on technet was to put synchronized(session) around
each JSP page)
Now we run the application under Apache/Jserv and with the same
Runtime packages as used in the Container and the problem
seems to have disappeared.
Here follows the code of the ApplicationPool class:
The class is based on an example posted on technet

this.releaseInstance(appModule);
this.releaseInstances();

pRetainState)
super.disconnect(pAppModule, pRetainState);
Here is the code of the applicationPool datatag:

Another thing is that the JSPApplicationRegistry contains a bug
(I think)
It doesn't use the HttpSessionTimeOut variable at all (see
following code)
this piece of code is a Method from the
JSPApplicationRegistry.java File taken from package
oracle.jbo.html.jsp;
static synchronized public void
registerApplicationFromPropertyFile(HttpSession session, String
sPropFileName)
if(!mPoolManager.isPoolCreated(sPropFileName))
registerApplicationFromPropertyFile(sPropFileName);
if (!PropertyConstants.TRUE.equals((String)session.getValue
(SESSION_INITIALIZED)))
Hashtable settings = getAppSettings(sPropFileName);
/* The timeout variable is declared here */
int nTimeOut = 300;
if (settings != null)
// see if we have a setting for the session timeout
String sTimeOut;
/* get the HttpSessionTimeOut variable */
if(settings.get("HttpSessionTimeOut") != null)
sTimeOut = (String)settings.get
("HttpSessionTimeOut");
if(sTimeOut != null)
/* Put the value in the variable... and that's the last thing it
does. nTimeOut isn't used anywhere in the class */
nTimeOut = Integer.parseInt(sTimeOut);
if(settings.get("ImageBase") != null)
session.putValue("ImageBase", settings.get
("ImageBase"));
else
settings.put("ImageBase", "/webapp/images");
session.putValue("ImageBase", "/webapp/images");
if(settings.get("CSSURL") != null)
session.putValue("CSSURL",settings.get("CSSURL"));
else
settings.put("CSSURL", "/webapp/css/oracle.css");
session.putValue
("CSSURL", "/webapp/css/oracle.css");
// place default renderers into session, these will not
be
// exposed via config file
session.putValue
("oracle_ord_im_OrdImageDomain_Renderer", "oracle.ord.html.OrdBui

session.putValue

Am I mistaken or is it a bug?
Thank you for your fast response.

First of all we get an JBO-30003: "The application pool, {AM Name}, failed to checkout an application module
instance."
The JBO-30003 exception is thrown whenever the pool cannot
properly create/recycle an application module. Please see the
exception details (scan the exception stack to find the exception
details) for more information regarding the "root" cause of the
exception.
We haven't found a way to alter the BC4J container timeout. Where do we customize the timeout?
The BC4J container is timed out when the HttpSession is timed
out. The session timeout is configurable via the web.xml file
for the J2EE application. Your servlet container may also
include another mechanism for setting a session timeout.
Second problem is that the J2EE Container stops functioning after a couple of requests. Even if an other browser
is started (on the same or different machine) the Container does
not respond to any request. We have found a Thread on technet
handling this kind of problem but the solution doesn't work in
our case.
The issue sounds like a deadlock. Please use kill -3 (Solaris)
or ctrl-break (NT) at the java server console to print the thread
stack trace to stdout. This will contain more information
regarding which threads are blocked and where. If you would like
you can send the stack trace to me via mail and I can take a look
at it.
The solution of synchronizing your pages with the HttpSession
context is required only if you are using the BC4J datatags with
HTML frames (i.e. have multi-threaded application module
access for a given session). Please note that this solution may
have a performance impact and should not be implemented unless
absolutely necessary.
Another thing is that the JSPApplicationRegistry contains a bug (I think). It doesn't use the HttpSessionTimeOut variable
at all (see following code)
This parameter was deprecated after 3.1. It looks like the code
which used the parameter may have been removed prematurely.
Sorry for the confusion. Please use the J2EE compliant
mechanisms mentioned above to configure the session timeout in
3.2.
Finally, please note that JDeveloper9i includes new integrated
features for the often requested feature of supporting different
db users with the same application pool! Please stay tuned.

Problem with code-Please Help!!!

Hey guys i have some problems with the following code:
1. I have to do a stutter and reverse of an array [ 2 4 ] and it should return [ 4 4 2 2 ]. I wrote the code and i get [ 2 2 4 4]. How can this be fixed?
public class Part1
     public static void main(String[] args)
          int[] values = {2, 4};
          stutterAndReverse(values);
     public static int[] stutterAndReverse(int[] values)
          //Stutter
          System.out.print("[ ");
          for (int i = 0; i < values.length; i++)
               for(int j = values.length-1; j >=0; j--)
                    System.out.print(values[i] + " ");
          System.out.print("] ");
          return values;
2. This one takes the array and returns the even numbers to the left and odds to the right. It works with the code i have so far but the odds on the right should be in order. For example an array of 6 gives the output [2, 4, 6, 5, 3, 1]. Mine gives [2, 4, 6, 1, 5, 3]. How can i fix this???
public class Part2
     public static void main(String[] args)
          int[] arr = new int[6];
          for(int i = 0; i < arr.length; i++)
          arr[i] = i + 1 ;
          printArray(arr);
          arr = evensToLeft(arr);
          //arr = oddsToRight(arr);
          System.out.println("Evens to the Left");
          printArray(arr);
     public static void printArray(int[] arr)
          System.out.print("[");
          for(int i = 0; i < arr.length; i++)
               System.out.print(arr);
               if(i < arr.length-1)
               System.out.print(", ");
               System.out.println("]");
     public static int[] makeArray(int n)
          int[] arr = new int[6];
          return arr;
     public static int[] evensToLeft(int[] arr)
          int split = 0;
          for(int i = 0; i < arr.length; i++)
               if(arr[i]%2==0) //even
                    swap(arr,i,split);
                    split++;
               return arr;
     public static void swap(int[] arr, int n1, int n2)
          int temp = arr[n1];
          arr[n1] = arr[n2];
          arr[n2] = temp;
Thank you for your time i really appreciate it.

now i'm more confused than ever...:(This'll probably make it worse :)
