使用的方法比较粗糙，先利用字符串分割，再使用正则匹配，将结果循环字符串处理，分为上下两轴。

import java.util.*;
import java.util.stream.Collectors;

public class Main {

    public static void main(String[] args) {
        Scanner s = new Scanner(System.in);
        String line = s.nextLine();
        String[] split = line.split("\\W");
        List<String> strings = Arrays.asList(split);
        List<String> resultList = strings.stream().filter(str -> str.matches("^[A|W|S|D][0-9]+$")).collect(Collectors.toList());
        int l =0;
        int r = 0;
        for (String move : resultList) {
            if (move.charAt(0) == 'A'){
                l -= Integer.parseInt(move.substring(1));
            }
            if (move.charAt(0) == 'D'){
                l += Integer.parseInt(move.substring(1));
            }
            if (move.charAt(0) == 'S'){
                r -= Integer.parseInt(move.substring(1));
            }
            if (move.charAt(0) == 'W'){
                r += Integer.parseInt(move.substring(1));
            }
        }
        System.out.println(l+","+r);
    }
}
