1、java課程設計報告題 目 ： JAVA簡易時間日歷程序?qū)W生姓名 ： 董兆軍 學 號 ： 專業(yè)班級 ： 信101 指導教師 ： 李紅強 課程設計題目 題目說明通過編寫一個基于JAVA的應用系統(tǒng)綜合實例，自定義一個日歷組件顯示日期和時間并進行適當?shù)墓δ軘U充，實踐Java語言編程技術。系統(tǒng)設計1 設計目標一個完整的程序應具有以下功能：1）顯示當月日歷、當前日期、當前時間；2）可查尋任意月以及任意年的日歷；3）使用圖形化界面能夠彈出對話框；5）正常退出程序。 2 設計思想設計一個類用來構成日歷系統(tǒng)的主窗口，然后編寫一個框架類顯示時間和提示信息。在設計中應用了多種容器和控件。系統(tǒng)模塊劃分public
