1、Java面向对象程序设计实验报告实验成绩：批阅教师：实验5图形用户界面实验学时： 2 实验地点： 本部 实验日期： 一、 实验目的浏览简单的GUI组件描述Java GUI的API层次结构使用框架，面板和简单的GUI组件创建用户界面理解布局管理器的作用使用FlowLayout，GridLayout和BorderLayout管理器在容器中布局组件使用JPane类作为子容器对swing组件应用边界，工具提示，字体和颜色等常用特性使用边界可视化地将用户界面组件分组使用ImageTcon类创建图形图标二、 实验内容1.分别使用FlowLayout和BorderLayout管理器编写程序（p34612.1

2、 12.2）2.（使用JPanel对按钮分组）改写前面的程序，创建同样的用户界面（p347 12.4）。三、 实验方法1）算法import java.awt.FlowLayout;public UseOfFlow() setLayout(new FlowLayout(FlowLayout.LEFT,10,20); JPanel pa = new JPanel(); pa.add(new JButton(white); pa.add(new JButton(blue); add(pa); 2）算法import java.awt.BorderLayout; public UseOfBorder()

3、 setLayout(new BorderLayout(10,20); JPanel pa = new JPanel(); pa.add(new JButton(white),BorderLayout.WEST); add(pa,BorderLayout.CENTER); 3）算法import java.awt.*;import javax.swing.*;public UseOfJPanel() setLayout(new BorderLayout(10,20); JPanel pa = new JPanel(); pa.add(new JButton(white); add(pa); 四、

8、args) UseOfFlow flow = new UseOfFlow(); flow.setTitle(Hello); flow.setLocationRelativeTo(null); flow.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); flow.setSize(350,250); flow.setVisible(true); 三import java.awt.*;import javax.swing.*;public class UseOfJPanel extends JFrame public UseOfJPanel() setL

9、ayout(new BorderLayout(10,20); JPanel pa = new JPanel(); JPanel pb = new JPanel(); pa.add(new JButton(white); pa.add(new JButton(blue); pa.add(new JButton(green); pb.add(new JButton(black); pb.add(new JButton(red); pb.add(new JButton(purple); pa.add(pb); add(pa); public static void main(String args) UseOfJPanel flow = new UseOfJPanel(); flow.setTitle(Hello); flow.setLocationRelativeTo(null); flow.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); flow.setSize(350,250); flow.setVisible(true); 五、 实验结果一二三六、 实验结论1）2）3）七、实验小结学好基础，多翻书，注意细节
