   JAD is Java Application Descriptor. It has instructions and details on how the j2me application should be installed on the user mobile phone, after the application is downloaded into the mobile phone.

   Usually every j2me game has images in it.
   For example consider the cricket java game,
   It will have the following elements,
   Cricket.class
   Batsmen.png (image of the batsmen)
   Bowler.png (image of the bowler)
   Fielder.png (image of the fielder)

   All these elements are needed for the proper working of the game,
   So we can put all these elements into a compressed zip format, and then send it to the user. Otherwise the user has to download each part separately for the game to run.

   This zip format is known as jar format in j2me. Zip format is only for desktop windows.

   So the zipped file Cricket.jar will have the files:
   Cricket.class
   Batsmen.png (image of the batsmen)
   Bowler.png (image of the bowler)
   Fielder.png (image of the fielder)

   But after the user downloads the jar file of the game he likes, he needs to install the game on his mobile. This installation information is present in the Cricket.jad file.

   Full form of:
   JAR: Java Archive or java zip format file
   JAD: Java Application Descriptor, has information for installing the application on the mobile phone.
