There were two programs. I compiled filemenu.java successfully and
it produced something called FileMenu.class.

I compiled it with $JAVAPATH/javac filemenu.java
Then I compiled window.java with $JAVAPATH/javac window.java
Which produced the error message listed below.

Throughout, CLASSPATH was . (just a dot for the current directory)

I believe that the compiler was unhappy because filemenu.java didn't
contain any public classes.
