您需要一个正则表达式“向后看” (?<=regex)，它匹配但确实消耗：
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：
45,890.00
12,345.00
23,765.34
56,908.50
