Clipboard (New)

Name

Clipboard (New)

[Graphic: Figure from the text]

Description

The Clipboard class is a repository for a Transferable object and can be used for cut, copy, and paste operations. The system clipboard can be accessed by calling Toolkit.getDefaultToolkit().getSystemClipboard(). You can use this technique if you are interested in exchanging data between your application and other applications (  Java or non-Java) running on the system. In addition, Clipboard can be instantiated directly, if "private" clipboards are needed.
