# Java Views

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

## Package Explorer View

The Package Explorer view shows a Java-specific view of resources inside Java projects in your workbench. The Java element hierarchy is defined by the project's build class paths and consists of elements like

- source folders and libraries
- packages
- source and class files
- types, methods, fields and initialzers

## Hierarchy View

The Hierarchy view allows you to look at the complete hierarchy for a type, only its subtypes, or only its supertypes. You can also open the hierarchy on a project, source folder or package.

## 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.
