我把表格的值存在一个字段里，逗号隔开，现在要做统计。怎么把第一个值相加，第二个值相加，以此类推

比如如下数组，怎么算呢，求大神算法：
String[] str = {
"8,6,8,3,2,02,1,1,6,07,08,09,01,11,13,86,7,3,4,1,3,1,1,1,4,1,2,3,4,5,18,58,1,3,4,2,-1,1,0,0,2,6,6,6,-3,6,-5,28,",
"8,0,5,0,0,0,0,0,0,0,0,0,0,0,0,13,2,0,4,0,0,0,0,0,0,0,0,0,0,0,0,6,6,0,1,0,0,0,0,0,0,0,0,0,0,0,0,7,",
"55,1,0,0,0,0,0,0,0,0,0,0,0,0,0,56,22,44,0,0,0,0,0,0,0,0,0,0,0,0,0,66,33,-43,0,0,0,0,0,0,0,0,0,0,0,0,0,-10,",
"77,066,55,0,0,0,0,0,0,0,0,0,0,0,0,198,33,33,33,0,0,0,0,0,0,0,0,0,0,0,0,99,44,33,22,0,0,0,0,0,0,0,0,0,0,0,0,99,"
};

例如对Str[0]进行处理 str[0].at(0)表示str[0]里面的第一个字符 也就是'8' 以此类推 str[0].at(1)=',' str[0].at(2)='6'

你可以

char ch=str[0].at(0);
int num=(int)ch;

这样num=8;
要计算str[0]中所以值相加 你就把str[0]中的所有数字取出来 然后相加就行了 然后计算str[1] str[2]...

谢谢楼上 我自己想了个办法 已经解决了
