You need to goto www.rentacoder.com for that. Or with such a simple app, you could even just Google it.

What exactly is wrong with Eclipse? There are plenty other out there, but I couldn't begin to suggest without knowing what is wrong with the one you use now. I prefer Eclipse myself anyway.

There is nothing wrong with it, but somehow the other my machine seems to be dead once eclipse has started.

You could always try the one that Sun provides if you download the right Java bundle. I believe they call it Netbeans. (http://www.netbeans.org/downloads/index.html[^])
I've played with it, but I prefer to use Eclipse myself.

I cannot advise better than the other answer you got. to me, Eclipse is the best IDE for Java/J2EE I know...

need help in writng a class WordStore in order to compile WordTest1, WordTest2, WordTest3 and WordTest4. Need to create some sort of data structure to store words in WordStore. must have methods
public void add(String word)
Adds a String to the collection
public int count(String word)
Returns the number of times a String is in the collection
public void remove(String word)
Removes one occurrence of a String from the collection, or leaves the collection unchanged if the String does not occur in it.
code for WordTest1:
import java.util.Scanner;
class WordTest1
{
public static void main(String[] args)
{
Scanner input = new Scanner(System.in);
WordGen.initialise(input);
System.out.print("Enter the number of words you wish to generate: ");
int n = input.nextInt();
WordStore words = new WordStore(n);
for(int i=0; i<n;> words.add(WordGen.make());
String line = input.nextLine();
System.out.println("Enter words to test, empty line to exit");
line = input.nextLine();
while(!line.equals(""))
{
String[] wordlist = line.split(" ");
for(int i=0; i<wordlist.length;> {
int count = words.count(wordlist[i]);
System.out.print("\""+wordlist[i]+"\" ");
if(count==0)
System.out.println("NOT generated");
else if(count==1)
System.out.println("generated once");
else
System.out.println("generated "+count+" times ");
}
line = input.nextLine();
}
}

long time1,time2;
int count;
time1 = new Date().getTime();
for(int i=0; i<n;> count=words.count(testWords[i]);
time2 = new Date().getTime();
System.out.print("Time taken to test membership of "+n+" words ");
System.out.println("is "+(time2-time1)+"ms");
}
}
code for WordTest3:
import java.util.*;
class WordTest3
{
public static void main(String[] args)

int count;
time1 = new Date().getTime();
for(int i=0; i<n;> words.add(testWords[i]);
time2 = new Date().getTime();
System.out.print("Time taken to add "+n+" more words ");
System.out.println("is "+(time2-time1)+"ms");
}
}
code for WordTest4:
import java.util.*;
class WordTest3
{
public static void main(String[] args)
{
Scanner input = new Scanner(System.in);
WordGen.initialise(input);
System.out.print("Enter the number of words you wish to generate initially: ");
int n = input.nextInt();

System.out.print("Enter number of words you wish to add: ");
n = input.nextInt();
String[] testWords = new String[n];

I assume this is a standard 3-wheel slot machine?
You should have a "slot" object defined somewhere, or at least some member variables to hold the "shape" and "color" values of each slot wheel.
The "if" statements aren't writable until we know what to compare them with.
For example, would it be "if (slot1Color == 0)" or "if (slot1.color == Color.RED)" or something else?
All you have written is a skeleton application. None of that concerns the question you wanted help with.
Don't let my name fool you. That's my job.

hi apurba,
s i had developed using threading concept.my chatserver is working on a default ip-address .0.0.0.what i want is my chatserver must start by picking up my systems Ip-address.here is the code m using.
protected void start_iChatServer(){
try{
iPortNo=Integer.parseInt(iAcquirePortNo.getText());
System.out.println("Port No." + iPortNo +"/n");
}catch(NumberFormatException e){
System.out.println("\n"+e);
System.out.println("Starting at default port : 1664...");
iPortNo=1664;
}
try{
iChatServer=new ServerSocket(iPortNo);
Int=iChatServer.getInetAddress();
i=iChatServer.getLocalPort();
sad=iChatServer.getLocalSocketAddress();
System.out.println("inetaddress=" + Int+ "localport="+i+ "getlocalsocketaddress="+sad);
isServerRunning=true;
System.out.println("\nServer set up and running at port "+iPortNo+"...\nWelcome to iChat Server v1.0...");
System.out.println("ichatserver=" +iChatServer);
iAcquirePortNo.setEnabled(false);
srtServer.setEnabled(false);
stpServer.setEnabled(true);
iClientList=new ArrayList();
iMainThread=new Thread(this,"iChat Server v1.0");
iMainThread.start();
}catch(IOException e){
System.out.println("\n"+e);
System.out.println("Error occured while setting up the server...\nTry another port...");
}
}
public void run(){
while(iMainThread!=null){
try{
Socket iNewClient=iChatServer.accept();
InfiniteChatClientHandler iNewClientHandle=new InfiniteChatClientHandler(this,iNewClient);
Thread.sleep(1000);
}catch(InterruptedException e){
}catch(IOException e){
}
}
}
Thank u
have a nice day.

I use Netbeans IDE.

With Java you create JARs instead. Google that phrase and that should help. I think there are ways to turn Java apps into .exe files, but I have never done it, and that completely destroys most pros of Java.

This is more like a general rant, but the problem I'm facing right now is with Java update, so here goes.
I have a Japanese Win XP computer because I work in a Japanese company. I cannot read Japanese. I specifically downloaded the English version of Java and installed it so I would be able to read the messages.
Now that it wants to update, it only does so in Japanese. That means the screens with all the prompting are in Japanese, and the buttons labeled "okay" or "no, this will wipe your hard disk, don't do it!" are also unreadable.
Can someone explain to me why Sun, in their infinite wisdom, decided users shouldn't be able to easily override their default computer settings so that the user can decide what language he wants to read? I already know why Microsoft does it, but "for the money" doesn't seem appropriate for Java.
Also, I realize that sometimes they say "just change your locale settings", but that isn't good enough. In XP, there are about 5 different locale-related items I can change, and at least two of them force me to reboot my computer. I want something to affect the Java update, and only the Java update (and possibly other Java settings). I don't want to reboot my computer just for one program, then reboot again when it's finished. That is a BAD SOLUTION.
*breathes*
Okay, I'm just going to go wipe my hard disk now. Thanks for listening.

I need an applet where a user enters (or cut-n-pastes) a UTF-8 string into a TextField. Then the user presses a button, and the UTF-8 text is copied into a string.
|
|
|
|
|
Then write one?
What is your specific question/problem?

I figured it out shortly after creating this post. I'm using JavaCC to parse my UTF8 inputs, and it's working fine! Thanks for your reply.
