EqualsIgnoreCase

I need to use equalsIgnoreCase to see if a string value matches the word "Yes" or not.
and I'm also asked about which one of the following ways I would choose, and why.
str = obj.getValue();
1) "Yes".equalsIgnoreCase(str);
2) str.equalsIgnoreCase("Yes");I know that they both work the same way; that is, they provide same results and both ways are frequently used. But I can't seem to find which one is a better one to use, after I've looked at the implementation of equalsIgnoreCase(String str) in String.java.
Could someone please explain this to me?
Thanks!

Thanks! You answered my question :-) I'll choose the 2nd one, then!

EqualsIgnoreCase() and J2Me Polish

Hi,
I am making an application in J2Me Polish. My application is using equalsIgnoreCase() method.
When i compile the application w/o Polish it works fine but it shows error when i compile it with the J2ME Polish.
The error is: cannot resolve symbol.
I have used Nokia/6681 group in the build.xml which supports MIDP 2.0/CLDC 1.1
But it i s not able to resolve this method.
Please help me in solving it.
Regards,
Divya

thanks for the information but cant we use equalsIgnoreCase method anyhow in J2ME Polish.Is this the limitation of the J2ME Polish.......

That's probably not the full stack trace? I'd say that you have an infinitive recursive call some where.

How can I use equalsIgnoreCase in JDBC Application to return database value

How can I ensure that the code will return a name from the database by using equalsIgnoreCase().
Please see below code .
public class RetrievEmp {
final static String FILE_NAME "c:\\project\\test.txt";
/** Retrieves data from Employee table with the specified column
* and employee's name.
public String getDataFromEmpTable(String empname, String column) throws Exception {
java.sql.Connection con = null;
String query = "select " + column + " from owner.Employee where NAME = ?";
ConnectionPool conPool = ConnectionPool.getPool();
ResultSet rs = null;
con = conPool.getConnection();
PreparedStatement ps = con.prepareStatement(query);
     try {
          ps.setString(1, name);
     rs = ps.executeQuery();
          if(rs.next()) {
rs.getString(1).equalsIgnoreCase(column);
     return rs.getString(1);
          else {

EqualsIgnoreCase problem

Ok here's the deal, new to java and always having problems.
For the class I'm in I had to create a program that would use equalsIgnoreCase to either terminate or continue the loop. That program worked just fine:
import java.util.*;
public class ExamAverager {
    public static void main(String[] args) {
            double sum;
            int numberOfStudents;
            double next;
            String answer;
            Scanner keyboard = new Scanner(System.in);
            do {
                 System.out.println("Enter all scores to be averaged.");
                 System.out.println("Enter a negative number after");
                 System.out.println("you have entered all the scores.");
                 sum = 0;
                 numberOfStudents = 0;
                 next = keyboard.nextDouble();
                 while (next >= 0)
                  sum = sum+next;
                  numberOfStudents++;
                  next = keyboard.nextDouble();
                      if (numberOfStudents > 0)
                           System.out.println("Average score: "+ (sum/numberOfStudents));
                      else
                           System.out.println("No scores to average.");
                      System.out.println("Want to average another exam?");
                      System.out.println("Enter yes or no.");
                      answer = keyboard.next();
               }while (answer.equalsIgnoreCase("yes"));
}Then we had to take the program and add to it, now it won't work. The compiler tells me it can't "find symbol variable answer"...can someone tell me the difference? or why it won't work this way? here's the new program code (nowhere near being done as I have awhile to go I don't even know if it will do what it is supposed to, but I can't find out b/c it won't get past the equalsIgnoreCase)

nevermind - I got it, I had everything set inside the do loop. ok. now here is my code, all fixed up and works like a charm problem is that i need to have the exit question be "Please enter a score from 0 to 100 or (Negative Number) to quit" so I need to use an int to get out of it, can you use a boolean expression in an equalsIgnoreCase? I thought it had to be a String, so what do I do? use a System.exit(0)?

Why does .equalsIgnoreCase() not return true when they're equal

http://pastebin.com/m741df92b
else if (message.matches("quit")) {
               System.out.println("inside quit thingie");
               // sender = sender.trim();
               for (int i = 0; i < admins.size(); i++) {
                    String admin = admins.get(i);
                    System.out.println("testing :" + admin + ": vs :" + sender
                              + ":");
                    if (sender.equalsIgnoreCase(admin)) {
                         System.out.println("quitting because of "
                                   + message.substring("quit".length() + 1));
                         super.quitServer(message.substring("quit".length() + 1));
                    } // end if
               } // end for
Output: (the first bit is logging the incoming message)
#TDWTFMafia:<btk> quit
inside quit thingie
testing :btk: vs :btk:Since posting the pastebin, I changed the code a bit so it would spit out the length along with what it's testing. that gave me
testing :btk: (3) vs :btk: (3)

Can you make sure the problem is not in
System.out.println("quitting because of "+ message.substring("quit".length() + 1));
super.quitServer(message.substring("quit".length() + 1));by replacing these 2 line with something like
System.out.println("quitting);
super.quitServer("quit");
{code}
Is the code you pasted surrounded by a try/catch statement? If message equals "quit" or something shorter your substring will throw a IndexOutOfBoundsException.

Help with equalsIgnoreCase()

Okay, I'm basically playing about and trying to learn different things :).
I've been trying to get equalsIgnoreCase() to work with a program I made:
     String t = "True";
          String f = "False";
          String ff = "";
          String starterInput = JOptionPane.showInputDialog(null, "Does the customer want a starter(true/false)?", "Starter choice", JOptionPane.QUESTION_MESSAGE);
          boolean starterChoice = starterInput.equalsIgnoreCase(t, f, ff);
          if (starterChoice)
                    System.out.println("Success");So, what I'm trying to do is to make the starterChoice Boolean true if starterInput matches the t, f or ff strings. However, I get a D:\JavaPro\Etc\src\Test.java:13: equalsIgnoreCase(java.lang.String) in java.lang.String cannot be applied to (java.lang.String,java.lang.String,java.lang.String)
        boolean starterChoice = starterInput.equalsIgnoreCase(t,f,ff);..error when I try to compile it. It works with just t, but not with more. Why is this?
Thanks.

It doesn't work with 2 strings though, just 1... Ideally I'd like to use 3 though, and can't see why that would be a problem with the function if it does allow 2...No, it uses 2. The one you invoke the method on, and the one you pass in as an argument

Use hashCode() to compare strings instead of equalsIgnoreCase()

The HashCode method has a contract which says
" If two objects are equal according to the equals(Object) method, then calling the hashCode method on each of the two objects must produce the same integer result. "
Hence does it not make sense to use hashcode() method to compare two strings instead of using equals() method ? For example instead of using
String s = "One";
System.out.println("Strings equal = "+s.equals("Two"));
we can write
String s = "One";
System.out.println("Strings equal = "+(s.hashCode()=="Two".hashCode()));

Here is just a short list of strings with 3 characters that has the same hashcodes:
2NX and 2O9 has same hashCode 50556

Difference in Null and Empty String

Hi,
I have been wondering about the difference between Null and Empty String in Java. So I wrote a small program like this:
public class CompareEmptyAndNullString {
     public static void main(String args[]) {
          String sNull = null;
          String sEmpty = "";
          try {
               if (sNull.equalsIgnoreCase(sEmpty)) {
                    System.out.println("Null and Empty Strings are Equal");
               } else {
                    System.out.println("Null and Empty Strings are Equal");
          } catch (Exception e) {
               e.printStackTrace();
This program throws Exception: java.lang.NullPointerException
     at practice.programs.CompareEmptyAndNullString.main(CompareEmptyAndNullString.java:10)
Now if I change the IF Clause to if (sEmpty.equalsIgnoreCase(sNull)) then the Program outputs this: Null and Empty Strings are Equal
Can anyone explain why this would happen ?
Thanks in Advance !!

Saish,
Whether you do any of the following code, the JUnit Test always passes: I mean he NOT Sign doesnt make a difference ...
assert (! "".equals(null));
assert ("".equals(null));
You probably have assertions turned off. Note the the assert keyword has nothing to do with JUnit tests.
I think that older versions of JUnit, before assert was a language keyword (which started in 1.4 or 1.5), had a method called assert. Thus, if you have old-style JUnit tests, they might still compile, but the behavior is completely different from what it was in JUnit, and has nothing to do with JUnit at all.
If you turn assertions on (-ea flag in the JVM command line, I think), the second one will throw AssertionError.

When i run(from terminal) separately in a new class with an image in an Imageview( inside a Vbox) and take the snapshot
of the imageview and write into the file using ImageIO.write(SwingFXUtils.fromFXImage(wim,null), outExtension, saveFile);
with any extension (jpeg,png etc) it is working fine.
Please help me.
Any small hint is also helpful.Please feel free to comment or give suggestion.

When i omit the line OutputStream out = new FileOutputStream(saveFile);
and write only
ImageIO.write((RenderedImage) bufferedImage, outExtension,saveFile);
//out.flush();
then saving the image even in "png" also fails.
The following is the error code:
Note : FileMenuController is my file where the saveImage() is wrtten.

File not found error

I get the following error, but don't know why it can't find the file. Is there anything in this script that would call "\" instead of "/"? Is there any line of code that will switch a wayward "\" back?

I know that is where my error is, but why and where is

Find line number in text file

Hi all,
I need to find the line numbers on a file where a particular string matches.
for example:
A lazy cat
A strong cat and it is black
Black is not good
So I will match for the word black and it will give the numbers say line 2 and 3 it found the match.
I am using the code:
try{
    // Open the file that is the first
    // command line parameter
      FileInputStream fstream = new FileInputStream("c:\\test.log");
    // Get the object of DataInputStream
      DataInputStream in = new DataInputStream(fstream);
      BufferedReader br = new BufferedReader(new InputStreamReader(in));
      String strLine;
     String[] arr= null;
    //Read File Line By Line
   String regex = "black";
   while ((strLine = br.readLine()) != null)   {
    // Split the sentence into strings based on space
       arr = strLine.split("\\s");
   if (arr[0].equalsIgnoreCase("black"))
      System.out.print("match found");
    Pattern p = Pattern.compile(regex);
    Matcher m = p.matcher(strLine);Thanks in advance.

It isn't rocket science.

Error while Enabling a user in OIM

Hi,
I have a requirement where i need to disable and enable OIM users based on a UDF . If the UDF says Active user should be enabled and if it says "deleted" user should be disabled. I'm able to "Disable" a user present in "Active" state but not vice versa. My entity adapter is as follows
statusUpdate(String userKey,String Status){
          OIMConnectionManagerImpl oimConn = new OIMConnectionManagerImpl();
          tcUserOperationsIntf tcUser = oimConn.getUserAPI();
          tcResultSet tcres = null;
               HashMap map = new HashMap();
               map.put("Users.Key",userKey);
               tcres = tcUser.findUsers(map);
               String s1=tcres.getStringValue("Users.Status");
               if(Status.equalsIgnoreCase("Active") )
                    if(s1.equalsIgnoreCase("Disabled")){
                         tcUser.enableUser(Long.parseLong(userKey));

Edited by: user10665408 on Jul 1, 2009 3:14 PM

I have done sm changes now:
Try this.
If some import is missing or some spelling mistakes are there just correct those. It's just for reference.
Put import for map also.
package com.Tst.oim;
import Thor.API.Operations.tcUserOperationsIntf;
import Thor.API.tcResultSet;
import Thor.API.tcUtilityFactory;
import com.thortech.xl.crypto.tcCryptoUtil;
import com.thortech.xl.crypto.tcSignatureMessage;
import com.thortech.xl.util.config.ConfigurationClient;
import java.util.Hashtable;
public class CreateFile {
tcUtilityFactory utilFactory = null;
tcSignatureMessage moSignature = null;
tcUserOperationsIntf moUserUtility = null;
tcResultSet userResultSet = null;
ConfigurationClient.ComplexSetting myConfig =
ConfigurationClient.getComplexSettingByPath("Discovery.CoreServer");
final Hashtable env = myConfig.getAllSettings();
public void Enable(String userid) {
try {
System.out.println("TRY");
moSignature = tcCryptoUtil.sign("xelsysadm", "PrivateKey");
utilFactory = new tcUtilityFactory(env, moSignature);
moUserUtility = (tcuserOperations)utilfactory.getutility("Thor.API.Operations.tcUserOperations");
Map a = new HashMap();
a.put("Users.User ID", userid);
tcResultSet userset = moUserUtility.findAllUsers(a);
long ukey = userset.getLongValue("Users.Key");
moUserUtility.enableuser(ukey);
} catch (Exception e) {
e.printStackTrace();

Stale data error while deleting a record

Hi
My design of this development is as follow...
1. Search Page in which users give some search criteria and results will be displayed in the results region on the same page. For each results record I have two buttons like 'Update' and 'Delete' so that users can delete the record or can update the record. For update i created a one more page where users can able to edit and save the data. I have two AM one for Search Page and one for Update Page.
Please find more details below.
intfEO based on PO_REQUISITIONS_INTERFACE_ALL
errorEO based on PO_INTERFACE_ERRORS
updateEO based on PO_REQUISITIONS_INTERFACE_ALL
VOs
intfVO based on intfEO and errorEO
updateVO based on updateEO
AM
intfAM based on intfVO
updateAM based on updateVO
Pages
searchPG based on intfAM
updatePG based on updateAM
Suppose I have one record in interface table with corresponding error record in error table.When users given the search criteria and hit enter they found a record. It means i have one record in the interface having one error record in the error table and both tables have same transaction id (primary key). So here user first try to update the record and it is working. After update he try to delete a record then I am getting below error. Please note that I am not getting this error when if i directly delete the record with out doing any update before delete. When ever users click on update icon then update PG will open and when users click on Apply button then data is getting updated in the database and page will forward to the search page.
Unable to perform transaction on the record.
Cause: The record contains stale data. The record has been modified by another user.
Action: Cancel the transaction and re-query the record to get the new data.
My UpdatePage Controller

Issue in RFCLookup UDF

Hi All,
Requesting your help in fixing an UDF issue.
This UDF is to check for a table entry and if not found it will create an alert with some source values.
Now the problem is, alert mails are getting created but the values are not getting passed.
Here is the source code:
AbstractTrace trace;
trace = container.getTrace();
MappingTrace trace1;
trace1 = container.getTrace();
Object cachedValue = null;
String result = null;
String sender = null;

Can someone check where could be the problem?

What is RfcLookupHandler? And where is RFC channel settings?
