Java編寫(xiě)-萬(wàn)年歷

1、22陜西師范大學(xué)遠(yuǎn)程教育學(xué)院考查課科目java程序設(shè)計(jì)姓 名霍娟學(xué) 號(hào)61861610310002專 業(yè)計(jì)算機(jī)科學(xué)與技術(shù)批 次 161層 次專升本學(xué)習(xí)中心銅川職業(yè)技術(shù)學(xué)院Java萬(wàn)年歷一 項(xiàng)目概述：這個(gè)項(xiàng)目是一個(gè)簡(jiǎn)單的Java萬(wàn)年歷，可以實(shí)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(shí)間。使用的是Oracle數(shù)據(jù)庫(kù)進(jìn)行連接。 二 具體功能介紹：（1）萬(wàn)年歷查詢：點(diǎn)擊圖形界面中的上年、下年鍵用來(lái)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(diǎn)擊上月或者下月來(lái)調(diào)整要查詢的月份，然后可以看到這個(gè)月的每一天所對(duì)應(yīng)的

2、星期。（2）Clock功能：在萬(wàn)年歷下面顯示當(dāng)前的年月日時(shí)分秒，相當(dāng)于一個(gè)時(shí)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(huì)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(wú)記錄；然后可以編輯這一天的備忘錄，編輯好了之后，點(diǎn)擊保存日志，彈出對(duì)話框某年某月某日保存日志嗎，點(diǎn)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(diǎn)擊右側(cè)的刪除日志，顯示刪除某年某月某日的日志嗎，點(diǎn)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(kù)進(jìn)行存儲(chǔ)和刪除操作。三 設(shè)計(jì)與實(shí)現(xiàn)（需要附全部代碼，GUI自動(dòng)生成代碼除外）：1 類
