1、精品资料java实验报告.信息工程学院Java语言课内实习报告 （20132014学年第 二学期） 实习题目：Swing 姓 名： 学 号： 专 业： 年级班级：一、实习目的 使用Java做图形界面啦，了解图形用户界面基本组件的使用，布局管理器如何对组件进行管理以及事件处理机制的应用。二、实习设计过程任务一：小小界面设计请设计一个界面，包括：菜单，文本框，按钮，标签，文本区，选择框，单选按钮和下拉列表。 任务二: 计算器（1） 编写一个计算器的程序，主界面由多个按钮组建、文本框组建构成。运行结果如图所示： 任务三:算数测试编写一个算术测试小软件，用来训练小学生的算术能力。程序由3个类组成，其中
2、Teacher类对象负责给出算术题目，并判断回答者的答案是否正确：ComputerFrame类对象提供的GUI界面看到题目并通过该GUI界面给出题目的答案；MailClass是主类。 任务四: 日历该窗口为BorderLayout布局。窗口的中心添加一个Panel容器：pCenter，pCenter的布局是7行7列的GridLayout布局，pCenter的中放置49个标签，用来显示日历。窗口北面添加一个Panel容器pNorth，其布局是FlowLayout布局，pNorth放置两个按钮：nextMonth和previousMonth按钮，单击nextMonth,可以显示当前月的下一个月的日
3、历；单击previousMonth按钮，可以显示当前月的上一个月的日历。窗口的南面添加一个Panel容器pSouth，其布局是FlowLayout布局，pSouth中请完成界面设计和相关功能。 三、调试过程中存在问题分析 布局过程中运行出来的图片效果不是自己设计的那样，有的文字被隐藏，重新调整文本框大小就弄好了。四、心得、体会与建议 这次实习过程中，感觉最有难度的是算数测试题目的设计，要判定结果是否正确。总体做起来还是很简单的。附录：题目1代码：import javax.swing.*;import java.awt.*;public class MyTu private JFrame fra
