# Java views

The Java development tools contribute the following views to the workbench:

## Package Explorer view

The Package Explorer view shows the Java element hierarchy of the Java projects in your workbench. It provides you with a Java-specific view of the resources shown in the Navigator. The element hierarchy is derived from the project's build class paths.
For each project, its source folders and referenced libraries are shown in the tree. You can open and browse the contents of both internal and external JAR files.

## Hierarchy view

The Hierarchy view allows you to look at the complete hierarchy for a type, only its subtypes, or only its supertypes.

## Projects view

The Projects view shows Java projects, source folders, external and internal libraries.
Note: source folders and libraries (both internal and external) presented in this view are not expandable. When they are selected, their contents are shown in the Packages view.

## Packages view

The Packages view shows a list of Java packages from the currently selected Java projects, source folders or libraries. Typically, the Projects view is used to make this selection.

## Types view

The Types view shows a list of Java types from the currently selected packages. Typically, the Packages view is used to make this selection.

## Members view

The Members shows the content of a type, compilation unit or CLASS file. Typically, the Types view is used to make this selection.
