I just installed the SDK and was trying to run a hellworld.class file that was compiled by javac, but when I do java helloworld.class in the correct directory it gives me this.
C:\Documents and Settings\Work\Desktop>java helloworld.class
Exception in thread "main" java.lang.NoClassDefFoundError: helloworld/class
Caused by: java.lang.ClassNotFoundException: helloworld.class
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)
at java.lang.ClassLoader.loadClassInternal(Unknown Source)
Does anyone know what the problem is or how to fix it?

Logan,
Welcome to JavaRanch!
The correct command is "java helloworld". The .class is not part of the command.
