.jar extention is a file used to easily transfer a java program from a pc to other. it is like a zip file which holds different files in it for easy transfer. it can be executable if it has a class which is executable i.e it can run without terminal window like in bluej.

jar also could be your custom library that you could use it in your programs. Suppose you have coded a class that save and read data to/from a file. Then instead of rewriting the same class in every program that should read/write to a file..you could just import your library and start using it.
