Text areas:

A text area is very similar to a text field. The main difference is that a text area is capable of containing a number of lines of text, rather than the single line found in a text field. Both the class JTextArea and the class JTextField inherit from a class known as  JTextComponent, which provides many of the methods that are used for manipulating objects described by these classes. Hence you will find quite a lot of commonality between the methods used for accessing and manipulating JTextArea and JTextField objects.

The code below creates a JTextArea object:

JTextArea ta = new JTextArea (4, 20);

It creates an empty text area that has 4 rows and 20 columns into which text is typed. The following code:

JTextArea ta = new
JTextArea ("This is some text to start off with. \n" + "Do you like it fi yes or no fi", 4, 20);

creates a text area that is already initialized with some text.

Useful methods include getText, setText(String) and, for JTextArea, append (String). As a default, text areas have 'word wrap' switched off. It is important to point out that as with lists, text areas do not automatically scroll. The JTextArea component has to be wrapped inside a JScrollPane to enable scrolling.
