How to Take Array Input in Java

Write a Java Program to take array input from the user. In this program, we are going to take only an integer array as input.

We are going to use the Scanner class to take integer inputs. The below are steps to take array input:

1. Take the size of the array as input.
2. Create the array of the above size.
3. Using for loop take integer elements from the user as input.
4. Print the array.

Java Program: 

import java.util.Scanner;

/**

public class Main {

    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
        System.out.println("Enter the size of array");
        int size = sc.nextInt();

        // create an array of given size
        int[] arr = new int[size];

        // take integer inputs using for loop
        System.out.println("Enter " + size + " elements");
        for (int i=0; i < size; i++) {
            arr[i] = sc.nextInt();
        }

        // print array
        System.out.println("The Array is: ");
        for (int i=0; i < size; i++) {
            System.out.print(arr[i] + " ");
        }
    }
}

Output: 

Enter the size of array
5
Enter 5 elements
1
2
3
4
5
The Array is: 
1 2 3 4 5
