Legacy Document

Important: The Java API for Cocoa is deprecated in Mac OS X version 10.4 and later. You should use the Objective-C API instead. For a tutorial on using Cocoa with Objective-C, see Cocoa Application Tutorial.

Communicating With Other Applications

Cocoa gives an application several ways to exchange information with other applications:

Pasteboards. Pasteboards are a global facility for sharing information among applications. Applications can use the pasteboards to hold data that the user has cut or copied and may paste into another application.
Services. Any application can access the services provided by another application, based on the type of selected data (such as text). An application can also provide services to other applications such as encryption, language translation, or record fetching.
Drag and drop. If your application implements the proper protocol, users can drag objects to and from the interfaces of other applications.
