Package javax.swing.text

package javax.swing.text

Provides classes and interfaces that deal with editable and noneditable text components. Examples of text components are text fields and text areas, of which password fields and document editors are special instantiations. Features that are supported by this package include selection/highlighting, editing, style, and key mapping.

Note: Most of the Swing API is not thread safe. For details, see Concurrency in Swing, a section in The Java Tutorial.
