A package is Java language construct that groups classes. You can add a package to any project in the workspace.
To create a new package:
The new package will appear in the Projects and Packages pages of the Workbench. To add a descriptive comment for the new package, select it, and fill in a description in the Comment pane.
Once you have created a package you can add classes and interfaces to it.
