 In this post, we will learn how to take input numbers into an Array using the scanner in Java.

Java Program to take input numbers into an Array

Write a Java Program that takes numbers as input and inserts those elements into an Array.

Example 1:
Input: number of elements = 5
         elements are = 1 2 3 4 5
Output: arr = [1, 2,3,4,5]

Java Program: 

// Java program to take input numbers into array

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 num = sc.nextInt();
		
		// declare array
		int[] arr = new int[num];
		
		System.out.println("Enter " + num + " numbers");
		for(int i = 0; i < num; i++) {
			arr[i] = sc.nextInt();
		}
		
		
		// print array
		System.out.print("Array elements are: ");
		for(int i = 0; i < arr.length; i++) {
			System.out.print(arr[i] + " ");
		}
		
		sc.close();
	}
}

Output: 

Enter the size of array
5
Enter 5 numbers
1
2
3
5
2
Array elements are: 1 2 3 5 2
