JLabel

is a component used to display decorative text on the screen to label some other component. The user cannot ever modify the text, unlike JTextfields. In AWT you use Label, in Swing JLabel. JLabel.setHorizonalAlignment( JLabel. LEFT ) or JLabel. setHorizontalAlignment( JLabel. RIGHT ) lets you control the justification. You control positioning of the text within the JLabel with setHorizonalAlignment and setVerticalAlignment and with setBorder. You control the positioning of the entire JLabel with your layout.

Gotchas

The background colour is ignored unless you do a setOpaque( true ).
Unlike a JTextField, you don’t need setContentType( "text/html" ) to embed HTML in the text.
