SWING TEXTFIELDS

A text field is a basic text control that lets the user enter a small amount of text. The class JtextField is used when creating a textfield. There are many other methods associated with textfields. When the user indicates that text entry is complete (usually by pressing Enter), the text field fires an action event. If you need to obtain more than one line of input from the user, you should use a text area instead.
textField = new JTextField(20);
textField.addActionListener(this);
