Easy distribution of Java applications

The jar format supports compression of Java files and resources , therefore reducing occupied space and download times

The jar utility creates a jar file for every .class file , therefore reducing the space occupied by classes

An application packaged in a jar archive can be run directly from the archive , without first extracting it

The JVM understand the jar format, therefore classes can be read directly from a jar archive

java -cp app.jar

java –jar app.jar
