暴力解法 将输入转化成字符串数组，然后将每个字符串再转换成char数组，然后通过判断和switch完成解答

public class Main {
    public static void main(String[] args) {
        //字符串问题
        Scanner sc = new Scanner(System.in);
        //根据输入，创建[以；分隔]的一个字符串数组
        String[] s = sc.next().split(";");
        int[] ans = new int[2];
        for (int i = 0; i < s.length; i++) {
            char[] c = s[i].toCharArray();
            if (c.length==2&&(c[0]=='W'||c[0]=='A'||c[0]=='S'||c[0]=='D')&&c[1]>='1'&&c[1]<='9') {
                int num = c[1]-'0';
                switch (c[0]){
                    case 'W':
                        ans[1]+=num;
                        break;
                    case 'A':
                        ans[0]-=num;
                        break;
                    case 'S':
                        ans[1]-=num;
                        break;
                    case 'D':
                        ans[0]+=num;
                        break;
                }
            } else if (c.length==3&&(c[0]=='W'||c[0]=='A'||c[0]=='S'||c[0]=='D')&&c[1]>='1'&&c[1]<='9'&&c[2]>='0'&&c[2]<='9') {
                int num = (c[1]-'0')*10 + (c[2]-'0');
                switch (c[0]){
                    case 'W':
                        ans[1]+=num;
                        break;
                    case 'A':
                        ans[0]-=num;
                        break;
                    case 'S':
                        ans[1]-=num;
                        break;
                    case 'D':
                        ans[0]+=num;
                        break;
                }
            }
        }
        System.out.println(ans[0]+","+ans[1]);
    }
