public class TestButton extends JFrame {

        Container contentPane = getContentPane();
        //获取资源
        URL resource = TestButton.class.getResource("4.jpg");
        //做成图标
        ImageIcon icon = new ImageIcon(resource);
        JButton jButton = new JButton();
        //按钮设置图标
        jButton.setIcon(icon);
        //设置按钮提示
        jButton.setToolTipText("这是一个图片按钮");
        contentPane.add(jButton);
        setVisible(true);
        setBounds(200,200,600,600);
        setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
    }

    public static void main(String[] args) {
        new TestButton();
    }
}

• 单选框按钮

public class TestButton02 extends JFrame{
    public TestButton02(){
        Container contentPane = getContentPane();
       /* //获取资源
        URL resource = TestButton.class.getResource("4.jpg");
        //做成图标
        ImageIcon icon = new ImageIcon(resource);*/
        //单选框
        JRadioButton jRadioButton01 = new JRadioButton("jRadioButton01");
        JRadioButton jRadioButton02 = new JRadioButton("jRadioButton02");
        JRadioButton jRadioButton03 = new JRadioButton("jRadioButton03");

        //因为单选框，只能选其中一个，所有要分组，分到一个组中
        //且按钮组只是一个组，不能添加到容器中
        ButtonGroup buttonGroup = new ButtonGroup();
        buttonGroup.add(jRadioButton01);
        buttonGroup.add(jRadioButton02);
        buttonGroup.add(jRadioButton03);

        contentPane.add(jRadioButton01,BorderLayout.NORTH);
        contentPane.add(jRadioButton02,BorderLayout.CENTER);
        contentPane.add(jRadioButton03,BorderLayout.SOUTH);
        setVisible(true);
        setBounds(200,200,600,600);
        setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);

    public static void main(String[] args) {
