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[] args) {} } |

You do have the JDK installed, right? |
