关于java图形设计（急求）

解决方案

    JRadioButton rdbtnNewRadioButton_2 = new JRadioButton("Chinese");
    rdbtnNewRadioButton_2.setFont(new Font("宋体", Font.PLAIN, 22));
    buttonGroup_1.add(rdbtnNewRadioButton_2);
    rdbtnNewRadioButton_2.setBounds(282, 360, 177, 29);
    contentPane.add(rdbtnNewRadioButton_2);

    JRadioButton rdbtnNewRadioButton_3 = new JRadioButton("English");
    rdbtnNewRadioButton_3.setFont(new Font("宋体", Font.PLAIN, 22));
    buttonGroup_1.add(rdbtnNewRadioButton_3);
    rdbtnNewRadioButton_3.setBounds(282, 397, 177, 29);
    contentPane.add(rdbtnNewRadioButton_3);

    final ButtonGroup group1 = new ButtonGroup();
    group1.add(rdbtnNewRadioButton_2);
    group1.add(rdbtnNewRadioButton_3);

    class FooterActionListener implements ActionListener {
        private int n;
        public void actionPerformed(ActionEvent ev) {
            if(ev.getSource().equals(rdbtnNewRadioButton_2))
                   //Middle m1=new HeaderOfChinese();
             if(ev.getSource().equals(rdbtnNewRadioButton_3))
                     n=2;
        }
        public int getN()
        {
            return n;
        }
      }

    ActionListener alisten1 = new FooterActionListener();
    /**
     * 为2个单选框添加事件
     */
    rdbtnNewRadioButton_2.addActionListener(alisten1);
    rdbtnNewRadioButton_3.addActionListener(alisten1);

解决方案二：

不知道你说的按钮信息是什么，你可以定义一个成员变量，每次按一个按钮，就设置它，这样它保存的就是最后一次按钮的信息了。

解决方案三：

JRadioButton rdbtnNewRadioButton_2 = new JRadioButton("Chinese");
rdbtnNewRadioButton_2.setFont(new Font("宋体", Font.PLAIN, 22));
buttonGroup_1.add(rdbtnNewRadioButton_2);
rdbtnNewRadioButton_2.setBounds(282, 360, 177, 29);
contentPane.add(rdbtnNewRadioButton_2);

JRadioButton rdbtnNewRadioButton_3 = new JRadioButton("English");
rdbtnNewRadioButton_3.setFont(new Font("宋体", Font.PLAIN, 22));
buttonGroup_1.add(rdbtnNewRadioButton_3);
rdbtnNewRadioButton_3.setBounds(282, 397, 177, 29);
contentPane.add(rdbtnNewRadioButton_3);

final ButtonGroup group1 = new ButtonGroup();
group1.add(rdbtnNewRadioButton_2);
group1.add(rdbtnNewRadioButton_3);

class FooterActionListener implements ActionListener {
    private int n;
    public void actionPerformed(ActionEvent ev) {
        if(ev.getSource().equals(rdbtnNewRadioButton_2))
               //Middle m1=new HeaderOfChinese();
         if(ev.getSource().equals(rdbtnNewRadioButton_3))
                 n=2;
    }
    public int getN()
    {
        return n;
    }
  }

ActionListener alisten1 = new FooterActionListener();
/**
 * 为2个单选框添加事件
 */
rdbtnNewRadioButton_2.addActionListener(alisten1);
rdbtnNewRadioButton_3.addActionListener(alisten1);
