德明第二次上課就因為找錯停車場而遲到十分鐘......
進教室後大家依舊忙碌，
雖然我知道現在的大學生不見得喜歡上課，
但老師還是用心的要把上課像拍戲一樣，
早就把今天三小時的劇本寫好，
開始上課.....
我化身攝影師，把攝影裝置裝好，
開拍，我變成主播，開始把編劇寫好的劇本開始鋪成，
把醜小鴨變天鵝的童話故事，融入到JAVA與Android，
原來 JAVA因為 Android變成天鵝，
原來昇陽(SUN)把JAVA賣給 甲骨文(Oracle)，因為Android而翻身，
一夕變為當紅炸子雞，所以不學好JAVA要學好Android只是緣木求魚。
於是將拿自己最熟悉的JAVA證照題目，
用最好的開發環境 ECLIPSE開發JAVA變得很重要，
可惜目前要找到如何用 ECLIPSE開發 JAVA的書籍似乎闕如，
但要開發JAVA與Androdi就一定要學好ECLIPSE，
於是劇本流程：
1.ECLIPSE的環境建置。
2.新建JAVA專案，開始寫101題樂透彩模擬程式。
3.轉成視窗介面。
4.輸出程執行檔，可以在WINDOWS、MAC、LINUS等環境執行。
5.將專案改成APP。
上下來還蠻緊湊，因為也要繳交作業，學生開始變得更積極。
回家之後我就變成後製，又搖身一半為部落客，
寫文分享JAVA開發經驗。
01_環境設定與JAV101題解說
02_JAVA101解題
03_JAVA101改成DecimalFormat版
04_JAV101改為swing版
05_JAVA101輸出成可執行的JAR檔
06_JAVA101轉成APP
07_介面設計與程式設計(宣告與連結與事件)
08_介面設計與程式設計
