Java字符串:如何从字符串"vt X,Y,Z"获取X,Y和Z的值

import java.util.regex.Matcher;
import java.util.regex.Pattern;

public class Main {
    public static void main(String[] args) {
        String input = "vt 123,456,789";
        Pattern pattern = Pattern.compile("vt (\\d+),(\\d+),(\\d+)");
        Matcher matcher = pattern.matcher(input);

        if (matcher.find()) {
            int x = Integer.parseInt(matcher.group(1));
            int y = Integer.parseInt(matcher.group(2));
            int z = Integer.parseInt(matcher.group(3));

            System.out.println("X: " + x);
            System.out.println("Y: " + y);
            System.out.println("Z: " + z);
        } else {
            System.out.println("No match found");
        }
    }
}

X: 123
Y: 456
Z: 789
