    Solution in java

    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<a.length;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]);
        }
    }
}

    Use stream and lambdas

    import java.util.List;
import java.util.Scanner;
import java.util.stream.Collectors;
import java.util.stream.Stream;

public class Solution {

    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        int n = scanner.nextInt();

        List<Integer> list = Stream.generate(scanner::nextInt).limit(n).collect(Collectors.toList());

        list.forEach(System.out::println);
    }
}

    Practicing mapping:

            //java8
        ArrayList<Integer> A = new ArrayList<>();
        while (scan.hasNextInt())A.add(scan.nextInt());
        int[] a = A.stream().mapToInt(i -> i).toArray();
