货币值字符串用逗号分隔

您需要一个正则表达式“向后看”

(?<=regex)

String regEx = "(?<=\.[0-9]{2}),";

这是您现在可以使用的测试用例：

public static void main(String[] args) {    String currencyValues = "45,890.00,12,345.00,23,765.34,56,908.50";    String regEx = "(?<=\.[0-9]{2}),"; // Using the regex with the look-behind    String[] results = currencyValues.split(regEx);    for (String res : results) {        System.out.println(res);    }}

输出：

45,890.0012,345.0023,765.3456,908.50
