Java JSONArray for循环 remove成员的一个好算法

好久没写日志了，今天来写一个，JSONArry fro循环判断value，移除不需要的，不需再将JSONArry再次转换成 map或list。

JSONArray移除成员只能通过for遍历取成员，判断后remove(index)，这样很明显是不行的，除非移除的成员只有1个，否则再你移除后for循环的遍历次数就被打乱了。你就会移除到不需要移除的成员。处理这个问题的方式其实很多的，比如创建list范型map将json遍历后一个一个弄到他们里面去......

我这里说的方式不需要创建LIST,MAP 直接就是用 remove和原本的JSONArry实现，并且效率应该是最高的。
