If you simply type “javac” and return at your command line (Win32 and Solaris), javac should dump a list of options that it understands. Typically you use javac like “javac MyClass.java”. There are a few important things to note about javac: • It is case-sensitive, even if your platform’s OS is not. “javac myclass.java” is NOT the same as “javac MyClass.java”. You will get weird errors such as “Class MyClass must be defined in a file called MyClass.java” if you do not provide the correct filename case. • It doesn’t like whitespace in filenames. • You must have set up your CLASSPATH correctly for it to work.

It also needs to be able to find the class you wish to compile. • It outputs compiled classes to your CLASSPATH. So if you compile a class under JNC.mySubPackage, the compiled .class file will appear under CLASSPATH/JNC/mySubPackage. If you have any quest
