Swing Core Components

The Component Set

Swing covers everything AWT does and much more, all in javax.swing:

• JButton, JLabel - basic output and actions.
• JTextField, JTextArea - input.
• JPanel - grouping container.
• JComboBox, JList - selections.
• JTable, JTree - rich data views.

Demo

JButton save = new JButton("Save");
JLabel msg = new JLabel("Ready");
JTextField name = new JTextField(12);
JTextArea body = new JTextArea(5, 20);
JComboBox<String> city = new JComboBox<>(new String[]{"Delhi","Mumbai","Pune"});
JList<String> skills = new JList<>(new String[]{"Java","Spring","SQL"});

Key Points

• All Swing controls start with J and live in javax.swing.
• JTable and JTree take a model (data) and render it automatically.
• JPanel with its own layout groups complex forms.
