Answer 1

class path tells java where the code (.class files) and any related data files are. It can contain paths to files or .jar files. .jar files are the same as .zip files except there's an extra file called the manifest file. Open one of the .jar files with winzip (or whatever tool you use) andyou will notices that most files are .class files (compiled java files).
