here is the code which worked for me. Hope it works for you as well...

import java.util.*;

public class Solution {

public static void main(String[] args) {

    Scanner scan = new Scanner(System.in);
    int n = scan.nextInt();
    int[] a = new int[n];
    for(int i = 0; i < n; i++){
        a[i]=scan.nextInt();
    }

    scan.close();

    // Prints each sequential element in array a
    for (int i = 0; i < a.length; i++) {
        System.out.println(a[i]);
    }
}

}

The Sample Output is wrong: it shows that you should also print n, but you mustn't do it because you'll not pass the tests. Please edit it.

Solution:

int[] a = new int[n];
        
for(int i = 0; i < a.length; i++) {
			a[i] = scan.nextInt();
}

Simple one

int a[]=new int[n]; for(int x=0;x<n;x++){ a[x]=scan.nextInt(); }
