实验五：GUI图形界面设计1实验目的掌握Awt与Swing的区别与联系；掌握Swing常用图像组件的使用；掌握主要的布局管理器的使用方法；了解事件处理机制；掌握Swing常用图像组件的使用；掌握固定菜单和弹出式菜单的创建和使用；2实验内容3. 实验结果1) 编写一个程序，它包括一个文本框和三个按钮，单击每个按钮时，在文本框中显示不同的文字。package button;import javax.swing.JPanel;import javax.swing.JFrame;import javax.swing.JButton;import javax.swing.JTextField;import java.awt.FlowLayout;import java.awt.event.ActionEvent;import java.awt.event.ActionListener;import java.awt.event.WindowAdapter;import java.awt.event.WindowEvent;public class Test extends JFrame implements ActionListenerprivate static final long serialVersionUID = 1L;private JPanel jPanel;private JButton jButton1,jButton2,jButton3;private JTextField tf1;public Test(String title) super(title); init();private void init()jPanel=new JPanel();jPanel.setLayout(new FlowLayout();tf1=new JTextField(20);jButton1=new JButton(按钮1);jButton2=new JButton(按钮2);jButton3=new JButton(按钮3);jButton1.addActionListener(this);jButton2.addActionListener(this);jButton3.addActionListener(this);jPanel.add(tf1);jPanel.add(jButton1);jPanel.add(jButton2);jPanel.add(jButton3);this.add(jPanel);this.setSize(300,100);this.setResizable(false);this.setVisible(true);this.addWindowListener(new WindowAdapter()public void windowClosing(final WindowEvent e) System.exit(0);); public void actionPerformed(ActionEvent e) if(e.getSource().equals(jButton1) tf1.setText(我爱我家); if(e.getSource().equals(jButton2) tf1.setText(我爱合师); if(e.getSource().equals(jButton3) tf1.setText(我爱JAVA); public static void main(String args) new Test(按钮显示不同文字); 2）设计一个窗体，上面有一个安宁。当鼠标移到按钮上时，立即隐藏该按钮，当鼠标离开该按钮时，显示该按钮。package org.awt;import java.awt.*;import java.awt.event.*;import javax.swing.*;public class TestEvent static JButton bt=new JButton(隐藏按钮);public static void main (Stringargs)Frame f =new Frame();f.setLocation(300,200);f.setSize(200,200);f.setLayout(null);/取消布局管理器；bt.addMouseListener(new MouseMove();/注册鼠标事件监听器；bt.setBackground(Color.cyan);bt.setBounds(new Rectangle(45,100,90,30);f.add(bt);f.pack();f.addWindowListener(new WindowAdapter()/关闭窗口public void windowClosing(WindowEvent e)System.exit(0););f.setVisible(true);/设置窗口可见；class MouseMove extends MouseAdapterpublic void mouseClicked(MouseEvent e)TestEvent.bt.setVisible(false);/鼠标单击Button按钮，按钮不可见；public void mouseExi
