public class WhatsGood

{
	public static void main (String[ ] args)
	{
		System.out.println ("Whats goin on?");
	}

}
		   

I am taking my first class on Java programming. Unfortunately my professor is of little help as he does not have much time to work with students. We are supposed to write this code then compile it. (which works fine) and then we are supposed to run it. When I try to run this program here is what comes up on my Command Prompt window.

C:\Documents and Settings\Alex (geo)\Desktop>java WhatsGood
Exception in thread "main" java.lang.NoClassDefFoundError: WhatsGood
Caused by: java.lang.ClassNotFoundException: WhatsGood
		at java.net.URLClassLoader$1.run(Unknown Source)

		at java.lang.ClassLoader.loadClassInternal(Unknown Source)

C:\Documents and Settings\Alex (geo)\Desktop>javac WhatsGood.java

Any help would be greatly appreciated....

Thanks So much

You need a main method.

It is the other way around

1) compile program
javac WhatsGood.java
2) run it
java WhatsGood

Make sure your .java is saved the same as you're class name.

WhatsGood

Is what you chose to call you're class so save your .java as WhatsGood.java and follow pbl's post above
