How to use ToolTip in Java Swing

To create a ToolTip in Java Swing, you can use the setToolTipText() method of a Swing component such as a JButton or a JLabel. Here is an example:

import javax.swing.*;

public class TooltipExample {
    public static void main(String[] args) {
        JFrame frame = new JFrame("Tooltip Example");
        JPanel panel = new JPanel();

        JButton button = new JButton("Hover over me");
        button.setToolTipText("This is a tooltip");

        panel.add(button);
        frame.add(panel);
        frame.pack();
        frame.setVisible(true);
    }
}

In this example, we create a JButton and set its tooltip text using the setToolTipText() method. When the user hovers the mouse over the button, the tooltip “This is a tooltip” will be displayed.

You can also set a tooltip for other Swing components like JLabel, JCheckBox, JRadioButton, etc. by calling the setToolTipText() method on the component instance.

Note that the tooltip will only be displayed if the component is enabled and visible.

Simple ToolTip Example:

Here’s a simple ToolTip example in Java Swing:

import javax.swing.*;

public class SimpleTooltipExample {
    public static void main(String[] args) {
        JFrame frame = new JFrame("Simple ToolTip Example");

        JButton button = new JButton("Hover over me");
        button.setToolTipText("This is a tooltip");

        frame.add(button);
        frame.pack();
        frame.setVisible(true);
    }
}

In this example, we create a JFrame and add a JButton to it. We set the text of the button to “Hover over me” and set the tooltip text to “This is a tooltip” using the setToolTipText() method. When the user hovers the mouse over the button, the tooltip will be displayed.

Note that you can also set the tooltip text for other Swing components such as JLabel, JCheckBox, JRadioButton, etc. using the same setToolTipText() method.
