    public static void main(String[] args){
        test_3_1 dis = new test_3_1();

        Scanner in = new Scanner(System.in );
        for (int i = 0;true;i++){
            dis.add(in.next());
            if(dis.getNote(i).equals("###")){
                break;
            }
        }
        int index = dis.getSize() - 1;
//        System.out.println(index);
        int[][] array = new int[index][index];
        for(int i = 0;i

后面实现的是同样的功能，但是代码优化。

改进： 尽可能多用库中自带的函数而不是自己去尝试定义。
