實現Java單選框的代碼是什么？動力節點小編來告訴大家。

public class JButtonDemo02 extends JFrame {
    public JButtonDemo02() {
        Container container = this.getContentPane();
        //將一個圖片變為圖標
        URL resource = JButtonDemo01.class.getResource("tx.jpg");
        Icon icon = new ImageIcon(resource);
        //單選框
        JRadioButton RadioButton1 = new JRadioButton("JRadioButton");
        JRadioButton RadioButton2 = new JRadioButton("JRadioButton");
        JRadioButton RadioButton3 = new JRadioButton("JRadioButton");
        //由于單選框只能選擇一個，分組
        ButtonGroup group = new ButtonGroup();
        group.add(RadioButton1);
        group.add(RadioButton2);
        group.add(RadioButton3);
        container.add(RadioButton1,BorderLayout.CENTER);
        container.add(RadioButton2,BorderLayout.NORTH);
        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 JButtonDemo01();
        new JButtonDemo02();
    }
}
