java課程設(shè)計簡單日歷程序

課程設(shè)計題目題目說明經(jīng)過編寫一個鑒于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合的功能擴大，實踐Java語言編程技術(shù)。系統(tǒng)設(shè)計2.1設(shè)計目標一個完好的程序應擁有以下功能：1）顯示當月日歷、目前日期、目前時間；2）可查尋隨意月以及隨意年的日歷；3）使用圖形化界面可以彈出對話框；5）正常退出程序。2.2設(shè)計思想設(shè)計一個類用來組成日歷系統(tǒng)的主窗口，而后編寫一個框架類顯示時間和提示信息。在設(shè)計中應用了多種容器和控件。2.3系統(tǒng)模塊區(qū)分publicstaticclassCalendarTable（日歷類）publicclassMyCalendarpublicstaticvoidmain(String[]extendsJAppletargs)（主日歷框架類）publicstaticclassRollbyJFrame（轉(zhuǎn)動時間類）圖1：簡略日歷的程序構(gòu)造圖初始化：publicvoidinit()達成界面初始化，形成一個以掛歷形式顯示目前日期的窗口。日歷描繪：（1）publicvoidupdateView()改變?nèi)掌诤筮_成更新界面；2）獲得系統(tǒng)日期并傳達日期數(shù)據(jù)并且在人工改變?nèi)掌诤蟮贸霎斎帐侵軒祝?）publicstaticvoidmain(String[]args)主函數(shù)達成系統(tǒng)各算法的調(diào)用并對主窗口的一些屬性進行設(shè)置；轉(zhuǎn)動時間：將時間以文本的形式在文本框中轉(zhuǎn)動播出，并能改變轉(zhuǎn)動的速度。使用類及接口只是簡單說明類的功能，詳盡資料請參看《JavaTM2PlatformStandardEd.6》的電子文檔，慣例的接口與包則省略不屑。以下是日歷程序塊中使用的類packagefancy;importjava.awt.*;importjava.util.*;//主要用此包中的日期和時間類importjavax.swing.*;以下是對轉(zhuǎn)動時間程序塊所使用的類和接口，用到準時器類Timer、用于監(jiān)聽鼠標單擊（焦點改變）事件用于響應鼠標單擊（焦點改變）事件、讓用戶從一個有序序列中選擇一個數(shù)字或許一個對象值的單行輸入字段。//在指準時間間隔觸發(fā)一個或多個
