java - 如何提取3个键之间的数值？

Question

我有这个字符串:页面:4，响应:5，alt:99

我想将值提取到数组中:

[4,5,99]

这是我的代码，有没有办法改进它？

pattern = "page: d+?,response: d+?, alt: d+?";

    String first = origianlString.replaceAll(pattern, "$0"); 
    String second = origianlString.replaceAll(pattern, "$1"); 
    String third = origianlString.replaceAll(pattern, "$2"); 

Answer 1

你可以试试这个:

String regex = "\\D+?(\\d+)\\D+?(\\d+)\\D+?(\\d+)";
String input = "page: 4, response: 5, alt: 99";
Pattern p = Pattern.compile(regex);
Matcher m = p.matcher(input);
if (m.find()) {
    String first = m.group(1);
    String second = m.group(2);
    String third = m.group(3);
    System.out.println("[" + first + "," + second + "," + third+ "]");
}

输出:

[4,5,99]
