从键盘输入数组时出错

Question

package array; 

import java.util.Scanner; 

public class Array { 

    public static void main(String[] args) { 
     int n; 
     Scanner input = new Scanner(System.in); 
     n = input.nextInt(); 
     int[] a = new int[n]; 
     for (int i = 0; i < n; i++) { 
      a[i] = input.nextInt(); 
     } 

     System.out.println(a); 

    } 

} 

Answer 1

您不能直接打印数组，您必须遍历它的值。

for (int j=0;j<a.length;j++){ 
    System.out.println(a[j]); 
}
