如何才能让数组实现连续的输入和输出

解释见注释

public static void main(String[] args) {

    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 = 0; i < n; i++)//定义数组长度为n,则i从0到n-1；不然数组不够放
    {      
        a[i] = ww.next();          
    }        
    //ttt();  //这个函数要传递数值，如ttt(5);
}       
public static void ttt(int man) {   

    for (int i = 0; i <= man; i++)//这里可以判断i<=Math.sqrt(man);减小运算量
    {      
        if (man == Math.pow(i, 2))    
        {       
            System.out.println("对");     
            break;      
            }           
        if(man == i){  
            System.out.println("错");   
            }
        }   
    }
