实验五 基于Swing的图形用户界面开发实验
一 实验内容
（1）完成开发界面如图所示，实现如下功能
选中“查看已有名片”按钮，程序处于查看状态，可以在“名片列表”中选择要查看的名片，程序在“名片详实信息”栏显示该名片的详实信息，此状态中名片信息处于不可编辑状态
选中“添加新名片”按钮，程序处于添加状态，所有关于明天信息的项目都处于可编辑状态，设置完成相关信息后，单击“添加”按钮，在“名片列表”中出现新添加名片的名称。单击“清空”按钮可以清空还没提交的内容
在查看状态和添加状态下，都可以通过点击“爱好”、“学历”单选按钮以显示名片的不同附加信息
（备注：名片附加信息部分，当点击“爱好”按钮时显示的如图1所示，当点击“学历”按钮时显示如图2所示。）

（2）记事本设计与实现
如图所示（1）编程实现如图所示的界面（2）实现文件、编辑、格式、查看，帮助菜单（3）实现记事本的基本功能
二 实验目的
（1）理解组件的分类
（2）掌握容器、布局管理器、普通组件的使用
（3）理解事件处理机制的工作原理
（4）掌握事件的添加和功能代码的编写方法
三 实验过程
（1）问题分析
1.
名片的设计除了使用最基本的组件，如 JButton,Jlist,JCheckBox, JTextField, JRadioButton, CardLayout 以外，最主要的是逻辑事件的编写，在成功布局完见面后， 就需要编写事件处理。首先，由于是名片信息，保存着一个人的基本信息，所以可以 用一个类来表示，如 PersonInf 类，其次，由于是多个人的信息，可以通过 ArrayList 来存放类；其次就是当点击按钮的时候，正确添加和显示信息，此处用到 cardLayout 布局，可以减少界面的复杂度，在使用JList的时候，除了加滚动条意外，还需要listModel 获取数据等。
