file format, filename extension (jar) A compressed
archive file containing
Java class files, filename extension:
"jar" for creating .jar files, similar to the standard
Unixtar command. As well as archiving and compressing the Java
class files, it also inserts a "manifest" file which can
contain information about the class files, such as a
digitalsignature. Combining class files into a single archive file
makes it possible to download them in a single
HTTPtransaction. This, and the
compression, speeds up execution
of Java programs delivered via the
Internet.
