An online Java Compiler

You can ‘Run’ your java code online, even if you dont have a compiler at your disposal, over here:- http://www.zamples.com/JspExplorer/index.jsp?format=jdk16cl

[update] Here is an online compiler for C#, Java, c++, Visual Basic (VB), Fortran, PHP, Perl, Ruby and many others!

CodePad is a an online compiler/interpreter with simple collaboration too.

You can paste your code to IDEOne to further compile and run.

    I usually use the one at MethodGamer.com
    It’s fairly simple and easy to use and is constantly undergoing development.
    They are supposedly looking for developers as well and you do not have to worry about the safety of your code as they do not save the code on their servers but allow you to save it on your own computer.
    That’s the only one I know of though.

      what to do,something prblm is in array,how to execute this,i am a beginner in java,please tell me what is the prblm

          you will give value at run time.
          eg. run in DOS then
          javac Multiplication.java
          java Multiplication 1

    • Mac says:

      This doesn’t work .. on Hitting the Debug/Run button , it gives the error Method Not Allowed on the default program >> Test.java

      • kannadasan says:

        hi, Mac! your program should be renamed in the format “classname.java”. for eg, if the name of the class in your program is phenom, then you should rename it as “phenom.java”. after doing so, run your program. it’ll work.sorry, if i’m wrong.

        • aaa says:

          It’s not necessary dat class name and file name should have same name.
          It just for progarammers ease. Try it dude.
          It means, “XYZ.java” having code :

          class abc
          {
          }

          will compile n execute sucessfully.

    there’s already tons of java programs you can compile & run directly online at http://www.krazykoder.com

    it allows you to run java console programs as well as java webapps (jsps, servlets, struts, ..) online.

    moreover, when a new user views your program, he can modify it online and enhance it further too.

    (the original program doesnt get affected as the new user gets a temporary copy of it)

    if my writing is too confusing, just head on to http://www.krazykoder and run a few programs, you’ll get what im talking about :)

    Write a function that returns an array of all elements of the natural numbers in order from first to last print.

    plz answer it with java and instantly

    • Raghav says:

      There are infinity natural numbers, but this will print the first n;

      import java.lang.*;
      public class PrintNaturals {
      const int n = 10; //substitute 10 for anything!
      public static void main(String[] args)
      {
      int[n] naturals; //array of natural numbers
      for (int i = 0; i < n; i ++)
      {
      naturals[i] = i + 1;
      }
      //Now you have an array of natural numbers, now let's print it
      for (int i = 0; i < n; i ++)
      {
      System.out.print((String)naturals[i]);
      }
      }
