It is useful and common practice to collect sets of related classes together in packages, and to store one or more packages in a JAR file.
You install a JAR file the same way as you install a class file. A JAR file can have the extension JAR or ZIP. Each JAR file must have a name in the database. Usually, you use the same name as the JAR file, without the extension. For example, if you install a JAR file named myjar.zip, you would generally give it a JAR name of myjar.
