  • 第5题：

    请完成下列Java程序：用一个边框布局来安排一个工具栏和一个卡片布局。工具栏可浮动，包括2个按钮，一个向前一个向后控制卡片的显示；卡片布局包括3张卡片，分别标识为card1，card2，card3。

    注意；请勿改动main()主方法和其他已有语句内容，仅在下划线处填入适当的语句。

    程序运行结果如下：

    import java.awt.*;

    import java.awt.event.*;

    import javax.swing.*;

    import javax.swing.border. LineBorder;

    public class ex24_2{

    private static CardLayout cl=new CardLayout();

    private static JPanel cp=new JPanel();

    public static void main(String[] args){

    JFrame. if=new JFrame();

    jf.setTitle("ex24_2");

    Container c=jf.getContentPane();

    JToolBar jtb=new JToolBar();

    JButton btnNext=new JButton(new ImageIcon("next.gif"));

    JButton btnPre=new JButton(new ImageIcon("back.gif"));

    jtb.add(btnPre);

    jtb.add(btnNext);

    cp.setLayout(cl);

    Dimension dim=new Dimension(150,80);

    cp.setPreferredSize(dim);

    cp.setBorder(new LineBorder(Color. BLACK));

    cp.add(new JLabel("cardl",JLabel.CENTER),"card1");

    cp.add(new JLabel("card2",JLabel.CENTER),"card2");

    cp.add(new JLabel("card3",JLabel.CENTER),"card3");

    c.add(jtb,BorderLayout.NORTH);

    c.add(cp,BorderLayout.CENTER);

    ActionListener al=new ActionResponse();

    ____________________________________;

    ____________________________________;

    jf.addWindowListener(new WindowAdapter(){

    public void windowClosing(WindowEvent we){

    System.exit(0);

    }

    });

    jf.pack();

    jf.setVisible(true);

    }

    static class ActionResponse implements ActionListener{

    public void actionPerformed(ActionEvent ae){

    if(ae.getActionCommand().equals("next"))

    cl.next(cp);

    else

    cl.previous(cp);

    }

    }

    }


    正确答案：btnNext．addActionListener(al) btnPre．addActionListener(al)
    btnNext．addActionListener(al) btnPre．addActionListener(al) 解析：本题主要考查工具栏和卡片布局的基本使用。解题关键是熟悉工具栏的设计和卡片布局的管理，熟悉事件处理机制，会制作图像按钮，会制作自己的事件监听器类。本题中，第1个空和第2个空都是需要填入注册监听器的语句，这里向前和向后2个按钮共用一个监听器，此监听器对象负责判断和处理相应的操作。
