import javax.swing.*;
import java.awt.*;
import java.net.URL;

public class JButtonDemo01 extends JFrame {
         //圖片按鈕
    public JButtonDemo01(){
        Container container = this.getContentPane();
        //圖片變為圖示
        URL resource = JButtonDemo01.class.getResource("tx.jpg");
        Icon icon =new ImageIcon(resource);

        //把這個圖示放在按鈕上
        JButton button = new JButton();
        button.setIcon(icon);
        button.setToolTipText("圖片按鈕");

        //add
        container.add(button);
        this.setVisible(true);
        this.setSize(500,500);
        this.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);

    }
    public static void main(String[] args) {
        new JButtonDemo01();
    }
}
 

單選按鈕(單選框)

package com.deng.lesson05;

import javax.swing.*;
import java.awt.*;
import java.net.URL;
//單選按鈕（單選框）
public class JButtonDemo02 extends JFrame {
    public JButtonDemo02(){
        Container container = this.getContentPane();
        //圖片變為圖示
        URL resource = JButtonDemo01.class.getResource("tx.jpg");
        Icon icon =new ImageIcon(resource);
        //單選框
        JRadioButton radioButton1 = new JRadioButton("JRadioButton1");
        JRadioButton radioButton2 = new JRadioButton("JRadioButton2");
        JRadioButton radioButton3 = new JRadioButton("JRadioButton3");
        //由於單選框只能選擇一位，分組，一個組中能選擇一個
        ButtonGroup group =new ButtonGroup();
        group.add(radioButton1);
        group.add(radioButton2);
        group.add(radioButton3);

        container.add(radioButton1,BorderLayout.SOUTH);
        container.add(radioButton2,BorderLayout.NORTH);
        container.add(radioButton3,BorderLayout.CENTER);

        this.setVisible(true);
        this.setSize(500,500);
        this.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
    }
    public static void main(String[] args) {
        new JButtonDemo02();
    }
}
 

複選按鈕(多選框)

package com.deng.lesson05;

import javax.swing.*;
import java.awt.*;
import java.net.URL;
//複選按鈕（多選框）
public class JButtonDemo03 extends JFrame {
    public JButtonDemo03(){
