## 18.57 java.awt.TextArea (JDK 1.0)

###

This class is a GUI component that displays and optionally edits multi-line text. The `appendText()`, `insertText()`, and `replaceText()` provide various techniques for specifying text to appear in the `TextArea`. Many important `TextArea` methods are defined by the `TextComponent` superclass.

See also `TextComponent` and `TextField`.
