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

你不能直接打印数组，你必须遍历它的值。

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