Help in Packages & Classes

I want to know how to view the contents of a java package and also the contents of java classes. I also want to know the use of various tools available in the jdk/bin folder (like javap, javah etc).Thanks to all who will consider my post.mohan

With 'unzip -l' you can view the contents of a jar file. With 'javap -classpath packaged.class.name' you can peruse a given class.Also see byte code disassemblers (e.g. jad) and code obfuscators for the advanced usage.
