Java Code Help-Palindromes

Sorry to trouble anyone, but I need help with coding a program dealing with Palindromes. I have some of the code already down, but I'm having trouble having the program recognize certain words as Palindromes (e.g. Racecar, madam, etc.). Note that this program is also case-sensitive. So I was just wondering if anyone had any code that could fix this maybe? If you do, it'd be appreciated. Thanks

public static void main(String[] args)
          String strPalin = null;
          if(args[0] != null)
               strPalin = args[0];
          byte[] b = strPalin.getBytes();
          int strlen = b.length;
          int i = (strlen - 1);
          int j = 0;
          byte[] c = new byte[strlen];
          while(i>-1)
               c[j] = b;
               i--;
               j++;
          String strrev = new String(c);
          if(strrev.equals(strPalin))
               System.out.println("Oops its a Palindrome:" +strPalin);
          }else{
               System.out.println("its not a Palindrome: " +strPalin);

Urgent java code help needed

i need java code for writing following lines in a file
<?xml version="1.0"?>
<!DOCTYPE wml PUBLIC "-//WAPFORUM//DTD WML 1.1//EN"
"http://www.wapforum.org/DTD/wml_1.1.xml">
Moreover i need code for reading word by word html file.
PLease reply as soon as possible.
iwapsms

for the html-part there are several html-parser, that bould whole parsetrees, which you can traverse (walk) through as you whish. just check google for it (something like: java html parser).
if that xml you have there is in String-form, just use a Filewriter
BufferedWriter writer = new BufferedWriter (new FileWriter (new File ("FilePath/filename.xml")));
writer.write (xmlString);
writer.close();however, if you have to juggle xml tags, content and attributes a lot, i'd recomend jdom to construct the xml and saxParser to write it.
again jsut google for it.

Search java code help

I am writing a small Java program and need help using a simple search code. Here is the code
public int indexOf(EltType e) {
        int i=0;
        for (i = currsize; i < currsize; i++){
            things[i] = e;
            e.equals(get(i));
        return -1;
    }Basically I want to search the array for e, and return its position, or -1 if e is not found. I know I have to use .equals(i) to compare e and get(i) but unsure where it goes.
Here is the method that calls it:
public void searchtester() {
        MyList<String> searchlist = new MyList<String>();
        searchlist.add("tangerine");
        searchlist.add("apple");
        searchlist.add("mango");
        searchlist.add("lime");
        searchlist.add("carrot");
        for (int i = 0; i<searchlist.size(); i++)
        System.out.println("searching for \"" + searchlist.get(i) + "\", result="
            + words.indexOf(searchlist.get(i)));
    }Please let me know what I am doing wrong.

sorry kevinaworkman, not trying to ignore any advice, just very new to java so trying to figure this out. It's okay, I just know from experience that breaking it up into smaller pieces will save you a ton of headaches.
Ok so I would imagine that loop:
for (i = currsize; i < currsize; i++)would run onceTake a look at the tutorial on [the for statement|http://java.sun.com/docs/books/tutorial/java/nutsandbolts/for.html] . If i starts out equal to currsize, and is only ever incremented, when will it be less than currsize? But even assuming that the loop runs once, what good would that be? Wouldn't you want the loop to run as many times as there are elements in your array?
things[i] = e;I'll give you a hint: if this line were executed, it would set the element at position i in the array equal to e. You want to check for equality, not set the whole array equal to e, right? Do you mean == in an if statement?
e.equals(get(i));Again, if this line was executed, it would check for equality between e and whatever get(i) returns. But then what are you doing with that boolean?
I want to see if i is equal to e then the result I want is the position of e and if i does not equal e then I want it to result in a -1, the issue is that it is giving me "-1" for all the results when I know that the first 3 items are in the list.You might want to step through your program with a debugger to see what's happening line by line. Or better yet, step through it with a piece of paper and a pencil. Go through the program as if you were the computer, following your program (and not the logic in your head you think the program does) exactly.
Some other things you might want to consider: the [if statement|http://java.sun.com/docs/books/tutorial/java/nutsandbolts/if.html] , arrays , and the above mentioned for loop tutorials.

Java code help needed for If-elseif statement

HI All,
Apologies for posting such a trivial thing but I am a novice in Java.
All I need is to code an If elseIF statement.
I tried the code below
String w = "SAPA";
String x = "SAPB";
if (a==w) ;
{Channel channel = LookupService.getChannel("BS_PROD","CC_RFC_LOOKUP");}
else if (a==x)
{ Channel channel = LookupService.getChannel("BS_PROD","CC_RFC_LOOKUP_ECQ"); }
It came back with the error

I should read the above structure and output it into a payload string variable ...
i have declared variables also
public void execute(InputStream in, OutputStream out)
          try
               trace.addInfo("Start of Extraction");
               OutputStream temp = new ByteArrayOutputStream(1024);

               String Payload = temp.toString();
               final String STARTTAG = "<row>";
               final String ENDTAG = "</row>";
               int Y_FILENAME_START = Payload.indexOf(STARTTAG);
               int Y_FILENAME_END = Payload.indexOf(ENDTAG);
               int spos = Y_FILENAME_START+STARTTAG.length();
               <b>if ( ( Y_FILENAME_END > spos) && (Y_FILENAME_END > 0 ) )</b>               {
                    Payload = Payload.substring(Y_FILENAME_START+STARTTAG.length() , Y_FILENAME_END);
                    trace.addInfo("Sucessfully Extracted");
Please suggest whether how can i read multiple rows .. as i am ABAPER i am unable to do it in Java..
I think the bold one reads only single row ... please suggest for reading multiple rows...
Thanks and Regards,

Please tell us what is the expected target structure.
Also, avoid to treat xml like strings. Use parsing methods (SAX, DOM). It is way easier, and they are mainly the reason why you should use java mappings over ABAP mappings.

Java code help

I have a class L1 in which I am creating an instance of another class Nav
like
Nav nav = new Nav(class.L2);
the argument in this Nav, shoukd be a class name how can I pass a classname as a argument. is it class.L2 or how?
In the Nav constructor I want to create a new instance of the class argument that was passed. How can I do this is there a way to do so? Thanks.

Try with:

It is compiling and runnung properly. Please Help me on this.
Thanks.
Satya.

You're mishandling the responses. You terminate if you don't get an "Ok" string, but that's not how success is defined - you should get a 200 code back, typically with an "OK" (not caps) message.
It doesn't help that you're ignoring all of the server output after each command, so you never find out if anything goes wrong.
You're also reinventing a wheel. The JavaMail API exists for this: http://java.sun.com/products/javamail/

Java code to create a new .txt file in FTP server --- Help

Hi,
I wrote a standalone java app which creates a .txt file in my local machine and transfers it to FTP server. But my requirement now is to create a new .txt file with the same content in FTP server itself instead of creating locally with basic java code.
I'm aware of transfering file from local machine to the FTP server using STOR command of FTP. But i never tried creating a new file & writing content into that in FTP server.
So, if any one did this before please help me out with source code or any idea ???
Thank you.
Vj.

thanks for your reply. yes i've seen the Apache Commons NET API , but there is no method or class to create a new file in FTP server. I'm really worried how to solve this problem ???Sure there is.
There's a method where you can write data to a file on the server using an OutputStream, right? Well, instead of writing to a FileOutputStream, write to that OutputStream instead. Remember to close the OutputStream and call the method which says you're finished with the command (I forget what it's called).

Being picky, that's not C++, that's C. Standard headers in C++ dont' have .h after them, loop variables are scoped with the for, you use constants rather than #defines, etc..
C and C++ both don't initialise arrays by default; you'd have to write an initialiser to get it to zero out the array:
int s[sz][sz] = {};gcc will insert a call to memset to zero the array.
If the author was assuming that the array was zeroed out, there would be no point zeroing the first row and column.
The code reads values which haven't been initialised. If you mark such values explicitly undefined, and change the program to report an error when undefined, then you get several cases where the program makes such report.
So either it' s a primitive random number generator (some random number generators use uninitialised memory as a source of randomness), or it's buggy, or it's processing undefined data and throwing away the result. Either way, it cannot be directly be ported to Java if the undefined values (which are limited to a small area of the ouput) are significant.

Help in translating JAVA code into CF

Hi all! I'm at the end of integrating an in-house calendar with Google calendars and all is working, however, I am stumped as to how implement callback functions. Here's what I'm trying to do as outlined on http://code.google.com/p/google-api-java-client/source/browse/Batch.wiki?repo=wiki
What I need to do is this section right here:
JsonBatchCallback<Calendar> callback = new JsonBatchCallback<Calendar>() {
public void onSuccess(Calendar calendar, HttpHeaders responseHeaders) {
    printCalendar(calendar);
    addedCalendarsUsingBatch.add(calendar);
public void onFailure(GoogleJsonError e, HttpHeaders responseHeaders) {
    System.out.println("Error Message: " + e.getMessage());
And then later pass it to:
client.calendars().insert(entry1).queue(batch, callback);
I believe I can pass one function by passing just the name of the function, but BatchCallback has two functions. Is this impossible to do in CF?
Thanks,
Ross.

1. In the future, please use a meaningful subject line, like "loop not performing last iteration." Just saying "Help in my java code" is useless. We know you need help with your Java code, else you wouldn't be posting here.
2. Repost your code without those annoying superfluous asterisks, and with proper indentation in the section that they are currently polluting. It's too hard to read as-is.

Run chm help file through java code

hello,
would you tell me how can i run a help.chm file using java code. i am trign this but no luck.
first try
Process pp=run.exec("C:/Program Files/Internet Explorer/IEXPLORE.exe ./res/bobftphelp.chm" );
Second try
Process pp=run.exec(" ./res/bobftphelp.chm" );
It run fine a help.doc file but not help.chm file.
please help me
Thanka in advance
Ravi Charan

The second address given to that function, does it relate to the class that its being called from? cause i've got
Runtime.getRuntime().exec("C:\\WINDOWS\\hh.exe .\\HelpFile_9_3.chm" );where HelpFile_9_3 is in the same folder as my class, but it won't work. Can anyone help?
Also, can you search within a chm file from Java? If I get that above code working, I presume it'll open the help file to the main page. I'd like to search within that document for a word or phrase - possible?
Thanks!
