JTextArea in Java Swing Example

The TextArea component in swing is similar to the TextArea component in AWT as it allows to display and edit multiple lines of plaintext. But unlike TextArea component in AWT, if all the text cannot be displayed in the available space in the component, scrollbars are not automatically added. In order to add scrollbars, you must insert it into a ScrollPane.

Commonly used methods of this latter component are:

This component is often used within a JScrollPane container. Thus when the number of lines is that the component is larger than the space allocated for distribution manager scroll bars appear.
