Swing Buttons
A Swing button is a type of button that allows a user to select an option from a list of choices. When the button is clicked, the selected option is automatically set as the new selected item in the component that contains the button.
Example:
java
// Create a button
JButton button = new JButton("Select an option");
// Add the button to a panel
JPanel panel = new JPanel();
panel.add(button);
// Set the action for when the button is clicked
button.addActionListener(new ActionListener() {
@Override
public void actionPerformed(ActionEvent e) {
// Get the selected option from the button
String selectedOption = button.getText();
// Set the selected option in a label
JLabel label = new JLabel("You selected: " + selectedOption);
// Add the label to the panel
panel.add(label);
}
});
Explanation:
We first create a JButton object and give it a text.
We then add the button to a JPanel and add a listener to it to handle the event when the button is clicked.
Inside the listener, we get the selected option from the button using the getText() method and store it in a variable.
We then set the selected option in a JLabel and add it to the panel.
When the button is clicked, the listener is triggered, and the selected option is set in the label.
Benefits of using Swing buttons:
They provide a convenient way for users to select an option from a list of choices.
They are easily added to any component in the Swing GUI.
They can be customized to look and behave according to the application's style
