Java package
open-in-new
<p>A Java package organizes <a href="/facts/Java_/9ScgFyAL">Java</a> <a href="/facts/Class_(computer_science)/zvzkSAtE">classes</a> into <a href="/facts/Namespaces/9efXwMtV">namespaces</a>, providing a unique namespace for each type it contains. Classes in the same package can access each other's package-private and protected members. </p><p>In general, a package can contain the following kinds of <a href="/facts/Datatypes/fcx5hgVL">types</a>: classes, <a href="/facts/Interface_(Java)/6TmqUypv">interfaces</a>, enumerations, records and <a href="/facts/Java_annotation/bEff4u2b">annotation</a> types. A package allows a developer to group classes (and interfaces) together. These classes will all be related in some way – they might all have to do with a specific application or perform a specific set of tasks. Programmers also typically use packages to organize classes belonging to the same category or providing similar functionality. </p>
