How to get eclipse working?

-----------------------------------

I get these problems everytime i uninstalled and reinstalled jre 6 to see if that would fix it but it doesn't.

java.lang.NoClassDefFoundError: Helloworld
Caused by: java.lang.ClassNotFoundException: Helloworld
	at java.net.URLClassLoader$1.run(Unknown Source)
	at java.security.AccessController.doPrivileged(Native Method)
	at java.net.URLClassLoader.findClass(Unknown Source)
	at java.lang.ClassLoader.loadClass(Unknown Source)
	at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source)
	at java.lang.ClassLoader.loadClass(Unknown Source)
Exception in thread "main" 

any suggestion on how to get this to work properly

The filename of the class must be the same as the name of the class. This is case sensitive. It must also be a public class.

Eg:

Filename: Helloworld.java

public class Helloworld {
public static void main(String
