[精品論文]JAVA萬年歷

畢業(yè)設(shè)計課程定做 QQ1714879127Java萬年歷一 項目概述：這個項目是一個簡單的Java萬年歷，可以實現(xiàn)所有年份的公歷日期的查詢，并且在相應(yīng)的日期做備忘錄，以及可以顯示當(dāng)前的日期以及時間。使用的是Oracle數(shù)據(jù)庫進(jìn)行連接。 二 具體功能介紹：（1）萬年歷查詢：點擊圖形界面中的上年、下年鍵用來調(diào)整要查詢的年份，或者可以直接在上年下年按鈕直接的文本框中輸入年份（負(fù)數(shù)表示公元前），以回車結(jié)束；點擊上月或者下月來調(diào)整要查詢的月份，然后可以看到這個月的每一天所對應(yīng)的星期。（2）Clock功能：在萬年歷下面顯示當(dāng)前的年月日時分秒，相當(dāng)于一個時鐘的功能。（3）記事本功能：可以任選某年某月的某一天，單擊，在右側(cè)會出現(xiàn)這一天的備忘錄，如果存在，則顯示某年某月某日有日志記載，是否想看，否則，則在文本框中顯示無記錄；然后可以編輯這一天的備忘錄，編輯好了之后，點擊保存日志，彈出對話框某年某月某日保存日志嗎，點擊保存，則日志被保存，反之未被保存；若想刪除某日的日志，則單擊這一天，然后點擊右側(cè)的刪除日志，顯示刪除某年某月某日的日志嗎，點擊是，則日志被刪除。從文件中讀取備忘錄的內(nèi)容，用數(shù)據(jù)庫進(jìn)行存儲和刪除操作。三 設(shè)計與實現(xiàn)（需要附全部代碼，GUI自動生成代碼除外）：1 類的設(shè)計（繼承、多態(tài)、數(shù)據(jù)結(jié)構(gòu)）：核心類是Month,Year,NotePad,Clock,DBAccess,CalendarPad.（其中繼承用粗體，接口用粗斜體，數(shù)據(jù)結(jié)構(gòu)是哈希表，用粗下劃線，多態(tài)用斜體+點點短線式下劃線）2 Java IO （文件訪問）：用的是粗體+浪線3 JDBC （數(shù)據(jù)庫訪問）：使用Oracle數(shù)據(jù)庫連接，是直連（雙下劃線）數(shù)據(jù)庫是：create table mynotes( mydate varchar2(50) primary key, note varchar2(100) not null);4 Socket + Multi-Thread：斜體（定義在Clock中的Thread t） 5 GUI （用戶界面）：點下劃線來表示GUI用戶界面6 其他功能：（無）以下是全部代碼（共六個.Java文件）/對月份的選擇package javaapplication13;import javax.swing.*;import java.awt.*;import java.awt.event.*;public class Month extends Box implements ActionListener/ActionListener接口 int month;
