How to set tooltip text for JCheckBox in Java?

For JCheckBox, use the following to set tooltip text:

checkBox1.setToolTipText("Sports Football"); checkBox2.setToolTipText("Sports Tennis");

Tooltip text is visible whenever you will place cursor on that particular text.

The following is an example. Here, we have set the tooltip text for both the sports:

Example

import java.awt.*; import java.awt.event.*; import javax.swing.*; public class SwingDemo {    private JFrame mainFrame;    private JLabel headerLabel;    private JLabel statusLabel;    private JPanel controlPanel;    public SwingDemo(){       prepareGUI();    }    public static void main(String[] args){       SwingDemo swingControlDemo = new SwingDemo();       swingControlDemo.showCheckBoxDemo();    }    private void prepareGUI(){       mainFrame = new JFrame("Java Swing");       mainFrame.setSize(600,400);       mainFrame.setLayout(new GridLayout(3, 1));       mainFrame.addWindowListener(new WindowAdapter() {          public void windowClosing(WindowEvent windowEvent){             System.exit(0);          }       });       headerLabel = new JLabel("", JLabel.CENTER);       statusLabel = new JLabel("",JLabel.CENTER);       statusLabel.setSize(350,100);       controlPanel = new JPanel();       controlPanel.setLayout(new FlowLayout());       mainFrame.add(headerLabel);       mainFrame.add(controlPanel);       mainFrame.add(statusLabel);       mainFrame.setVisible(true);    }    private void showCheckBoxDemo(){       headerLabel.setText("Favourite Sports");       final JCheckBox checkBox1 = new JCheckBox("Football");       final JCheckBox checkBox2 = new JCheckBox("Tennis");       checkBox1.setToolTipText("Sports Football");       checkBox2.setToolTipText("Sports Tennis");       checkBox1.setMnemonic(KeyEvent.VK_F);       checkBox2.setMnemonic(KeyEvent.VK_T);       checkBox1.addItemListener(new ItemListener() {          public void itemStateChanged(ItemEvent e) {             statusLabel.setText("Football Checkbox: " + (e.getStateChange()==1?"checked":"unchecked"));          }       });       checkBox2.addItemListener(new ItemListener() {          public void itemStateChanged(ItemEvent e) {             statusLabel.setText("Tennis Checkbox: "+ (e.getStateChange()==1?"checked":"unchecked"));          }       });       controlPanel.add(checkBox1);       controlPanel.add(checkBox2);       mainFrame.setVisible(true);    } }

The output is as follows. Here, you can see on mouse hover the tooltip is visible:
