I am using IBM JDK 1.5 on Fedora Core 6 PowerPC.  HelloDate.java compiles fine and produces a working class.  When I try to compile HelloDate2.java, I get an error.  What does this error message actually mean?

[ben@tidbit bens]$ javac HelloDate2.java
----------

                                 ^^^^^^^^^
