货币值字符串用逗号分隔
我有一个字符串,其中包含格式货币值(如)45,890.00
和多个值(以逗号分隔)45,890.00,12,345.00,23,765.34,56,908.50
。
我想提取并处理所有货币值,但无法为此找到正确的正则表达式,这是我尝试过的
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}[,]";
String[] results = currencyValues.split(regEx);
//System.out.println(Arrays.toString(results));
for(String res : results) {
System.out.println(res);
}
}
输出为:
45,890 //removing the decimals as the reg ex is exclusive12,345
23,765
56,908.50
有人可以帮我这个吗?
回答:
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:
45,890.0012,345.00
23,765.34
56,908.50
