Just few questions as a beginner in Java:
1.- What can I find inside jar files, classes...?
1.- Can I "unzip" a jar file in order to see its contents?. If it is possible, how can I do this?
Thanks in advance.

JAR file will contain the class files and auxiliary resources associated with applets and applications.
You can view the contents of jar file using
c:\jdk\bin>jar xf <jar-file name>.
The jar tool can be found in the bin directory of of JDK.
Hope this helps

on windows you can open it with winzip.
jar files are using the zip algorithm so you should be able to rpocess them with any zip tool available.
