Post your code.

public class HelloWorld { public static void main(String[] args) { System.out.println("Hello, World!"); } } // This is simple program but after successful compiles it doesn't showing any output. what should i do now?

Here it works showing output. Have you save the file name with HelloWorld? One more thing did you the following command to compile the code:

javac HelloWorld.java

Actually if you have used class name in small letters instead of capital one as you have saved your class with HelloWorld.

Check it out. Even then if error occurs, post the error.

Here it works and showing output. Have you save the file name with HelloWorld? One more thing did you use the following command to compile the code?:

javac HelloWorld.java

Actually if you are compiling the class with the class name written in small letters and you are saving your file with capital letters, then it gives error. Check the case.

Check it out. Even then if error occurs, post the error.
