接收数组

数组长度未知

输入用例：2,3,4,5,1

public static void main(String[] args) {
           Scanner in = new Scanner(System.in);
           while (in.hasNext()){
               String s = in.nextLine();

               String[] str = s.split(","); //按照逗号分隔
               int[] a = new int[str.length];
               for (int i = 0; i < str.length; i++) {
                   a[i] = Integer.parseInt(str[i]);
                   System.out.println(a[i]);
               }
           }
       }
