JAR versus Package

Hi,

Package:

A package allows a developer to group classes (and interfaces) together. These classes will all be related in some way – they might all be to do with a specific application or perform a specific set of tasks. For example, the Java API is full of packages. One of them is the javax.xml package. It and its subpackages contain all the classes in the Java API to do with handling XML.

Jar file:

a JAR file (or Java ARchive) aggregates many files into one. Software developers generally use .jar files to distribute Java applications or libraries, in the form of Java class files and associated metadata and resources (text, images, etc.). JAR files are built on the ZIP file format.
