Java source program compilation and execution issues

When writing Java programs, encountered the problem of compilation does not pass:

The error message displays GBK, which may be caused by a problem with the character set:

An option-encoding Utf-8 was specified for the Java command before the compilation was successful ^_^

However, when you execute with the Javac command, you encounter a problem that causes the execution to fail:

Comment out the following code, and the compilation and execution of the source files are successful.

Would that be the reason, I think of the solution, looking for Niang asked, the answer is surprisingly consistent: CLASSPATH environment variable problem, but the CLASSPATH variable from JDK 1.5 no longer set. Finally found the answer on a forum:

The Java package name must be entered in the parent directory. Class name

Finally, Kung Fu is not a conscientious, problem solved.
