Is Java working?

Verify that your installation of Java was successful by compiling the following Java example. Create a file, HelloWorld.java, containing the following:

public class HelloWorld { 
    public static void main ( String[] args) {
        System.out.println( "Hello World!"); 
    } 
}

C:\> javac HelloWorld.java 
C:\> java HelloWorld 
Hello World! 
C:\> 

If you do not see the line “Hello World!”, or see messages then something is wrong with your installation. Please refer to Sun's website for assistance. The Java Tutorial might prove quite useful in troubleshooting any of these problems.
