How To Make JAR File | Jar File Creation

To create .jar file that is executable and platform independent
Java Archive file.

First you need to Create manifest file that having information like
main-class (class having main method), version etc..

Ex: manifest.fs
Main-Class: HelloWorld
Version: 1.0

To create .jar file you need to use 'jar' command located at
\jdk\bin directory.

Usage:
jar {ctxu}[vfm0Mi] [jar-file] [manifest-file] [-C dir] files ...
Options:
-c create new archive
-t list table of contents for archive
-x extract named (or all) files from archive
-u update existing archive
-v generate verbose output on standard output
-f specify archive file name
-m include manifest information from specified manifest file
-0 store only; use no ZIP compression
-M do not create a manifest file for the entries
-i generate index information for the specified jar files
-C change to the specified directory and include the following file
If any file is a directory then it is processed recursively.
The manifest file name and the archive file name needs to be specified
in the same order the 'm' and 'f' flags are specified.

Example 1: to archive two class files into an archive called classes.jar:
jar cvf classes.jar Foo.class Bar.class
Example 2: use an existing manifest file 'mymanifest' and archive all the
files in the foo/ directory into 'classes.jar':
jar cvfm classes.jar mymanifest -C foo/ .
