package com.jia.lesson;

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

public class JButton01 extends Jframe {
    public JButton01() {

        //使用Jframe第一步new容器
        Container container = this.getContentPane();

        //将一个图片变为图标
        URL url = JButton01.class.getResource("dsBuffer.jpg");
        ImageIcon imageIcon = new ImageIcon(url);

        //把这个图标放到按钮上
        JButton jButton = new JButton();
        jButton.setIcon(imageIcon);
        jButton.setToolTipText("图片按钮");

        container.add(jButton);

        this.setVisible(true);
        this.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
        this.setSize(500, 300);

    }


    public static void main(String[] args) {
        new JButton01();
    }
}

2.单选框

package com.jia.lesson;

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

public class JButton02 extends Jframe {
    public JButton02() {
        Container container = this.getContentPane();

        //将一个图片变为图标
        URL url = JButton01.class.getResource("dsBuffer.jpg");
        ImageIcon imageIcon = new ImageIcon(url);

        //单选框
        JRadioButton jRadioButton1 = new JRadioButton("button1");
        JRadioButton jRadioButton2 = new JRadioButton("button2");
        JRadioButton jRadioButton3 = new JRadioButton("button3");

        //由于单选框只能选择一个,所以分组,一个组中,只能选择一个
        ButtonGroup buttonGroup = new ButtonGroup();
        buttonGroup.add(jRadioButton1);
        buttonGroup.add(jRadioButton2);
        buttonGroup.add(jRadioButton3);

        container.add(jRadioButton1, BorderLayout.CENTER);
        container.add(jRadioButton2, BorderLayout.NORTH);
        container.add(jRadioButton3, BorderLayout.SOUTH);

        this.setVisible(true);
        this.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
        this.setSize(500, 300);


    }


    public static void main(String[] args) {
        new JButton02();
    }
}

3.复选框

package com.jia.lesson;

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

public class JButton03 extends Jframe {
    public JButton03() {
        //使用Jframe第一步new容器
        Container container = this.getContentPane();

        //将一个图片变为图标
        URL url = JButton01.class.getResource("dsBuffer.jpg");
        ImageIcon imageIcon = new ImageIcon(url);

        //多选框
        JCheckBox jCheckBox1 = new JCheckBox("checkbox1");
        JCheckBox jCheckBox2 = new JCheckBox("checkbox2");
        JCheckBox jCheckBox3 = new JCheckBox("checkbox3");

        container.add(jCheckBox1,BorderLayout.CENTER);
        container.add(jCheckBox2,BorderLayout.NORTH);
        container.add(jCheckBox3,BorderLayout.SOUTH);

        this.setVisible(true);
        this.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
        this.setSize(500, 300);
    }


    public static void main(String[] args) {
        new JButton03();
    }
}
