## 图片按钮 ##

**示例代码：**

public class JButtonDemo01 extends JFrame {
        
        public JButtonDemo01() {
        
            Container container = this.getContentPane();
            //将图片变成图标
            URL resource = JButtonDemo01.class.getResource("tx.jpg");
            Icon icon = new ImageIcon(resource);
            //图标放在按钮上
            JButton button = new JButton();
            button.setIcon(icon);
            button.setToolTipText("图片按钮");
            //add
            container.add(button);
    
            this.setVisible(true);
            this.setSize(500,300);
            this.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
        }
        public static void main(String[] args) {
        
            new JButtonDemo01();
        }
    }

## 单选框 ##

**示例代码：**

public class JButtonDemo02 extends JFrame {
        
        public JButtonDemo02() {
        
            Container container = this.getContentPane();
            //将图片变为图标
            URL resource = JButtonDemo02.class.getResource("tx.jpg");
            Icon icon = new ImageIcon(resource);
    
            //单选框
            JRadioButton radioButton1 = new JRadioButton("JB1");
            JRadioButton radioButton2 = new JRadioButton("JB2");
            JRadioButton radioButton3 = new JRadioButton("JB3");
    
            //由于单选框只能选一个，分组，一个组中只能选一个(单选即不分组)
            ButtonGroup g = new ButtonGroup();
            g.add(radioButton1);
            g.add(radioButton2);
            g.add(radioButton3);
    
            container.add(radioButton1,BorderLayout.NORTH);
            container.add(radioButton2,BorderLayout.CENTER);
            container.add(radioButton3,BorderLayout.SOUTH);
    
    
            this.setVisible(true);
            this.setSize(500,300);
            this.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
        }
        public static void main(String[] args) {
        
            new JButtonDemo02();
        }
    }

## 复选框 ##

**示例代码：**

public class JButtonDemo03 extends JFrame{
        
        public JButtonDemo03() {
        
            Container container = this.getContentPane();
            //将图片变为图标
            URL resource = JButtonDemo03.class.getResource("tx.jpg");
            Icon icon = new ImageIcon(resource);
    
            //多选框，即不分组
            JRadioButton radioButton1 = new JRadioButton("radioButton1");
            JRadioButton radioButton2 = new JRadioButton("radioButton2");
            JRadioButton radioButton3 = new JRadioButton("radioButton3");
            container.add(radioButton1,BorderLayout.NORTH);
            container.add(radioButton2,BorderLayout.CENTER);
            container.add(radioButton3,BorderLayout.SOUTH);
    
    
            this.setVisible(true);
            this.setSize(500,300);
            this.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
        }
        public static void main(String[] args) {
        
            new JButtonDemo03();
        }
    }
