信息工程学院Java语言课内实习汇报（～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，理解图形顾客界面基本组件的使用，布局管理器怎样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种界面，包括：菜单，文本框，按钮，标签，文本区，选择框，单项选择按钮和下拉列表。任务二:计算器编写一种计算器的程序，主界面由多种按钮组建、文本框组建构成。运行成果如图所示：任务三:算数测试编写一种算术测试小软件，用来训练小学生的算术能力。程序由3个类构成，其中Teacher类对象负责给出算术题目，并判断回答者的答案与否对的：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。窗口的中心添加一种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。窗口北面添加一种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,可以显示目前月的下一种月的日历；单击previousMonth按钮，可以显示目前月的上一种月的日历。窗口的南面添加一种Panel容器pSouth，其布局是FlowLayout布局，pSouth中请完毕界面设计和有关功能。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、体会与提议这次实习过程中，感觉最有难度的是算数测试题目的设计，要鉴定成果与否对的。总体做起来还是很简朴的。附录：题目1代码：importjavax.swing.*;importjava.awt.*;publicclassMyTu{ privateJFrameframe;
