    抱歉再度提問@@
    第五題的要求
    (3)如果此次總利潤超過 20000，則使用Exception 印出信息【This order exceeds 20000:xx】，將總利潤帶入xx。　直接用if 真的OK嗎@@ 雖然這有點太深 讓我不懂到底該怎寫

      謝謝您的提醒~當初考的時候還沒有這個勘誤~所以就用一般的方法帶過了~
      有更新在上方的程式碼了~
      如果有更新錯的話，在這附上原始碼：http://goo.gl/2GpwGi

      也謝謝您找出了許多的錯誤^^"
      筆者原本有想過要整個code翻新，但有兩個點卡了我~"~
      1.JAVA6出來也有段時間了(太舊)，TQC+也差不多要出JAVA8的考題了吧xD
      2.我現在主要在寫C/C++，沒有一個較長的時間回去寫JAVA QQ

      刪除
