Welcome to JavaRanch. How are you running this code? Post the commends you're entering on the command line.

So: The exception talks about "a" and "A". What could that mean? And what is a java.lang.NoClassDefFoundError? If you don't know, read its javadocs.

(Don't get confused by your use of "String[] a", that's not what this so about. But you should nonetheless change that to "String[] args", because that is what everyone uses. So unless you want to confuse every Java developer under the sun except yourself... :-) )
