第四天，本來想進一步去改進《猜猜看》游戲的。可是非常多問題都不理解。也不熟悉怎么去弄到連接數(shù)據(jù)庫。統(tǒng)計猜對次數(shù)，所以并沒有進行再多的改動。

基本上就是這種執(zhí)行結(jié)果了

課程實訓(xùn)的過程是艱辛的，本來就不是非常熟悉JAVA代碼編程，僅僅能靠網(wǎng)絡(luò)上的知識還有老師發(fā)的提示代碼進行改動還有修飾。完畢《猜猜看》游戲。

基本上已經(jīng)完畢。盡管執(zhí)行了起來。可是僅僅是非常主要的。沒有統(tǒng)計次數(shù)。沒有弄到連接數(shù)據(jù)庫或者保存文件。

總結(jié)

以上是生活随笔為你收集整理的《JAVA课程设计》实训第四天——《猜猜看》游戏的全部內(nèi)容，希望文章能夠幫你解決所遇到的問題。
