I need help! [message #720291]

I study computer technology first year. And I´ve written this program :
public class Program4b
{
public static void main(String[]args)
{

double lengde=5.0; //legg inn grunnflatens lengde
double hoyde=6.0; //legg inn trekantens hoyde

double svar=(lengde*hoyde)/2; // gjør beregning

System.out.println("Arealet til trekanten er:"+svar+"cm2"); //skriv ut
}
}

But I keep getting the same console error no matter what I do:

Exception in thread "main" java.lang.NoClassDefFoundError: Program4
Caused by: java.lang.ClassNotFoundException: Program4
at java.net.URLClassLoader$1.run(URLClassLoader.java:202)
at java.security.AccessController.doPrivileged(Native Method)
at java.net.URLClassLoader.findClass(URLClassLoader.java:190)
at java.lang.ClassLoader.loadClass(ClassLoader.java:306)
at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301)
at java.lang.ClassLoader.loadClass(ClassLoader.java:247)

I need help to fix this, is there anyone who knows what to do?

All help will be appreciated Smile

The error tells you want is wrong. I'll point out the relevant parts:

public class Program4b

Caused by: java.lang.ClassNotFoundException: Program4

Note that this not really related to Eclipse, a better forum would be:
