这个组合怎么生成？

[水木夕阳]

string s = "86,87|57|47,69";//接收一个字符串，进行|分割成数组，这个是动态的，数组不知道有多少个 ,也可能是86,87|57|47,69|98,78
//打印出组合，如
//86,57,47
//86,57,69
//87,57,47
//87,57,69
//如果是86,87|57|47,69|98,78
//打印出组合，如
//86,57,47,98
//86,57,47,78
//86,57,69,98
//86,57,69,78
//87,57,47,98
//87,57,47,78
//87,57,69,98
//87,57,69,78

1.字符串分割
2.排列组合

哦，1L算法完全正确，不过好像看错题目了，第一步是按照“|”分割，第二步是“，”分割

public class Test{
    public static void main(String[] args) {
        String s = "86,87|57|47,69";
        String data = "";
        String[] dataStrArray = s.split("\\|");
        doSomthing(dataStrArray, 0, data);
    }

    public static void doSomthing(String[] dataStrArray, int index, String data) {
        String[] temp = dataStrArray[index].trim().split(",");
        for (String ss : temp) {
            if (index == dataStrArray.length - 1) {
                data += ss;
                System.out.println(data);
                data = data.replace(ss, "");
            } else {
                data += ss + ",";
                index += 1;
                doSomthing(dataStrArray, index, data);
                index -= 1;
                data = data.replace(ss + ",", "");
            }
        }
    }
}
