Java JSONArray for循環 remove成員的一個好算法

 很久沒寫日誌了，今天來寫一個，JSONArry fro循環判斷value，移除不須要的，不需再將JSONArry再次轉換成 map或list。

 

JSONArray移除成員只能經過for遍歷取成員，判斷後remove(index)，這樣很明顯是不行的，除非移除的成員只有1個，不然再你移除後for循環的遍歷次數就被打亂了。你就會移除到不須要移除的成員。處理這個問題的方式其實不少的，好比建立list範型map將json遍歷後一個一個弄到他們裏面去......

    我這裏說的方式不須要建立LIST,MAP 直接就是用 remove和本來的JSONArry實現，而且效率應該是最高的。
