實驗五 基于Swing的圖形用戶界面開發實驗
一 實驗內容
（1）完成開發界面如圖所示，實作如下功能
選中“查看已有名片”按鈕，程式處于查看狀態，可以在“名片串列”中選擇要查看的名片，程式在“名片詳實資訊”欄顯示該名片的詳實資訊，此狀態中名片資訊處于不可編輯狀態
選中“添加新名片”按鈕，程式處于添加狀態，所有關于明天資訊的專案都處于可編輯狀態，設定完成相關資訊后，單擊“添加”按鈕，在“名片串列”中出現新添加名片的名稱，單擊“清空”按鈕可以清慷訓沒提交的內容
在查看狀態和添加狀態下，都可以通過點擊“愛好”、“學歷”單選按鈕以顯示名片的不同附加資訊
（備注：名片附加資訊部分，當點擊“愛好”按鈕時顯示的如圖1所示，當點擊“學歷”按鈕時顯示如圖2所示，）
圖1
圖2
（2）記事本設計與實作
如圖所示（1）編程實作如圖所示的界面（2）實作檔案、編輯、格式、查看，幫助選單（3）實作記事本的基本功能
二 實驗目的
（1）理解組件的分類
（2）掌握容器、布局管理器、普通組件的使用
（3）理解事件處理機制的作業原理
（4）掌握事件的添加和功能代碼的撰寫方法
三 實驗程序
（1）問題分析
1.
名片的設計除了使用最基本的組件，如 JButton,Jlist,JCheckBox, JTextField, JRadioButton, CardLayout 以外，最主要的是邏輯事件的撰寫，在成功布局完見面后， 就需要撰寫事件處理，首先，由于是名片資訊，保存著一個人的基本資訊，所以可以 用一個類來表示，如 PersonInf 類，其次，由于是多個人的資訊，可以通過 ArrayList 來存放類；其次就是當點擊按鈕的時候，正確添加和顯示資訊，此處用到 cardLayout 布局，可以減少界面的復雜度，在使用JList的時候，除了加滾動條意外，還需要listModel 獲取資料等，

編程實作如圖所示的界面，實作檔案、編輯、格式、查看，幫助選單，實作記事本的基本功能
（2）代碼撰寫
