用Java剪切/分割字符串

Question

我有一个字符串如下:

2012/02/01,13:27:20,872226816,-1174749184,2136678400,2138578944,-17809408,2147352576

我想提取数字:872226816,所以在这种情况下我假设在第二个逗号开始读取数据之后,然后以下逗号结束读取数据.

示例输出:

872226816

Answer 1

s = "2012/02/01,13:27:20,872226816,-1174749184,2136678400,2138578944,-17809408,2147352576";
s.split(",")[2];
