Solution

For a simple example, it uses mouselistener and mosueadapter to monitor mouseexited() and mouseentered() events on jlabel. When any of these methods is called (that is, when the mouse hovers over the label), the picture will change:

import java.awt.BorderLayout;
import java.awt.Container;
import java.awt.event.MouseAdapter;
import javax.swing.*;

public class LabelHoverTest extends JFrame {

    Icon pic1;
    Icon pic2;
    JLabel label;

    public LabelHoverTest(String title) {
        super(title);
        pic1 = UIManager.getIcon("OptionPane.informationIcon");
        pic2 = UIManager.getIcon("OptionPane.questionIcon");
        createAndShowUI();
    }

    public static void main(String[] args) {
        SwingUtilities.invokelater(new Runnable() {

            @Override
            public void run() {
                new LabelHoverTest("Label Hover Test").setVisible(true);
            }
        });
    }

    private void createAndShowUI() {
        setDefaultCloSEOperation(JFrame.EXIT_ON_CLOSE);
        setResizable(false);
        addComponentsToPane(getContentPane());
        setSize(300,300);
        setLocationRelativeTo(null);
        setVisible(true);
    }

    private void addComponentsToPane(Container contentPane) {
        label = new JLabel(pic1);

        contentPane.add(label,BorderLayout.CENTER);

        label.addMouseListener(new MouseAdapter() {

            @Override
            public void mouseEntered(java.awt.event.MouseEvent evt) {
                label.setIcon(pic2);
            }

            @Override
            public void mouseExited(java.awt.event.MouseEvent evt) {
                label.setIcon(pic1);
            }
        });
    }
}
