jar file type no. 1:
Compressed file package for classes and data: Java Archive

Application: Java platform applications, environment | More information: java.sun.com
Description:
The JavaTM Archive (JAR) file format enables you to bundle multiple files into a single archive file. Typically a JAR file contains the class files and auxiliary resources associated with applets and applications.
The JAR file format provides many benefits:
Security: You can digitally sign the contents of a JAR file. Users who recognize your signature can then optionally grant your software security privileges it wouldn't otherwise have.
Decreased download time: If your applet is bundled in a JAR file, the applet's class files and associated resources can be downloaded to a browser in a single HTTP transaction without the need for opening a new connection for each file.
Compression: The JAR format allows you to compress your files for efficient storage.
Packaging for extensions: The extensions framework provides a means by which you can add functionality to the Java core platform, and the JAR file format defines the packaging for extensions. Java 3D? and JavaMail? are examples of extensions developed by SunTM.
By using the JAR file format, you can turn your software into extensions as well.
Package Sealing: Packages stored in JAR files can be optionally sealed so that the package can enforce version consistency. Sealing a package within a JAR file means that all classes defined in that package must be found in the same JAR file.
Package Versioning: A JAR file can hold data about the files it contains, such as vendor and version information. Portability: The mechanism for handling JAR files is a standard part of the Java platform's core API.

JAR has a similar command and option feature set to the PC archiver ARJ, but it is not archive compatible with ARJ. JAR comes in a 16 bit DOS version and a 32 bit Windows version. This format is unrelated to the Sun .JAR archive format.
