这是我的代码，如何才能让数组实现连续的输入和输出

Question

public static void main(String[] args) {                // TODO Auto-generated method stub      Scanner sc = new Scanner(System.in);        System.out.println("请输入数字个数");        int n = sc.nextInt();       System.out.println("请输入数字");         Scanner ww = new Scanner(System.in);        String[] a = new String[n];         for (int i = 1; i <= n; i++) {          a[i] = ww.next();           }           ttt();   }           public static void ttt(int man) {        for (int i = 0; i <= man; i++) {               if (man == Math.pow(i, 2))              {                   System.out.println("对");                  break;                  }               if(man == i){                   System.out.println("错");              }   }   }     }

你全用nextline吧，要不然回车换行会折腾死你
