1.图片按钮代码示例

package com.yundait.lesson05;import javax.swing.*;
import java.awt.*;
import java.net.URL;public class JButtonDemo01 extends JFrame {public JButtonDemo01(){Container container = this.getContentPane();//将一个图片变为一个图标URL resource = JButtonDemo01.class.getResource("VCG211239251300.jpg");ImageIcon icon = new ImageIcon(resource);//将这个图标放在按钮上JButton jButton = new JButton();jButton.setIcon(icon);jButton.setSize(50,50);jButton.setToolTipText("这是一个图片按钮");//在容器上添加按钮container.add(jButton);this.setVisible(true);this.setSize(600,700);this.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);}public static void main(String[] args) {new JButtonDemo01();}
}

运行结果：

2.单选框代码示例：

package com.yundait.lesson05;import javax.swing.*;
import java.awt.*;
import java.net.URL;public class JButtonDemo02 extends JFrame {public JButtonDemo02(){Container container = this.getContentPane();//单选框JRadioButton jRadioButton1 = new JRadioButton("JRadioButton1");JRadioButton jRadioButton2 = new JRadioButton("JRadioButton2");JRadioButton jRadioButton3 = new JRadioButton("JRadioButton3");//创建一个按钮组，把按钮放在组中，组中的按钮只能选择一个ButtonGroup buttonGroup = new ButtonGroup();buttonGroup.add(jRadioButton1);buttonGroup.add(jRadioButton2);buttonGroup.add(jRadioButton3);//在容器上添加按钮container.add(jRadioButton1,BorderLayout.NORTH);container.add(jRadioButton2,BorderLayout.CENTER);container.add(jRadioButton3,BorderLayout.SOUTH);this.setVisible(true);this.setSize(600,700);this.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);}public static void main(String[] args) {new JButtonDemo02();}
}

运行结果：

2.多选框代码示例

package com.yundait.lesson05;import javax.swing.*;
import java.awt.*;public class JButtonDemo03 extends JFrame {public JButtonDemo03(){Container container = this.getContentPane();//创建多选框JCheckBox jCheckBox1 = new JCheckBox("jCheckBox1");JCheckBox jCheckBox2 = new JCheckBox("jCheckBox2");//将多选框添加到容器中container.add(jCheckBox1,BorderLayout.NORTH);container.add(jCheckBox2,BorderLayout.CENTER);this.setVisible(true);this.setSize(600,700);this.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);}public static void main(String[] args) {new JButtonDemo03();}
}

运行结果：
