It is generally used to distribute Java classes and associated metadata. Go to wiki/JAD and wiki/JAR for more information.

Q: Do I need to download both jad and jar files?
A: If you are downloading Yafi to your computer you need both files. After you copy them to your device you can run JAD file. It will ask you to install and look for JAR in the same directory. When you are downloading Yafi directly to your mobile phone from yafi.pl/mobile you can run JAD file and it will download JAR after you accept to install it.
