1.Bug:DM_BOXED_PRIMITIVE_FOR_PARSING
"Boxing/unboxing to parse a primitive", A boxed primitive is created from a String, just to extract the unboxed primitive value. It is more efficient to just call the static parseXXX method
原因：裝箱和拆箱的問題，把一個字符串裝箱，解析獲取箱子中原始值。更有效率就是使用靜態方法，parseXXX 方法。
原始代碼：Integer.valueOf(okNums) == 0
修改后的代碼：Integer.parseInt(okNums) == 0
