# Sum of Two Arrays in Java

In this article, you will see the Sum of two arrays in Java. Here, we will take two integer arrays and store the sum of both arrays into a 3rd integer array.

## Example#1. Sum of two arrays in Java

```package com.javacodepoint.array;

public class SumOfTwoArray {

public static void main(String[] args) {

// 1st Array
int arr1[] = { 4, 5, 1, 6, 4, 15 };

// 2nd Array
int arr2[] = { 3, 5, 6, 1, 9, 6 };

// 3rd Array to store the Sum
int arr3[] = new int[arr1.length];

// Adding arr1 and arr2 and storing into arr3
for (int i = 0; i < arr1.length; i++) {
arr3[i] = arr1[i] + arr2[i];
}

// Print the arr3 elements
for (int i = 0; i < arr3.length; i++) {
System.out.print(arr3[i] + " ");
}

}

}

```

OUTPUT:

7 10 7 7 13 21

## Example#2. Addition of two arrays in Java using Scanner

In this example, we will read the array elements from the users using the Scanner java class. Let’s see the java code below:

```package com.javacodepoint.array;

import java.util.Scanner;

public class SumOfTwoArrayExample2 {

public static void main(String[] args) {

// Creating scanner object for reading user inputs
Scanner sc = new Scanner(System.in);

// Read the size of the Array
System.out.println("Enter the size of the Array: ");
int n = sc.nextInt();

// Declare the arr1 & arr2 of given size
int arr1[] = new int[n];
int arr2[] = new int[n];

System.out.println("Enter " + n + " element(s) of the Array1: ");
for (int i = 0; i < n; i++) {
arr1[i] = sc.nextInt();
}

System.out.println("Enter " + n + " element(s) of the Array2: ");
for (int i = 0; i < n; i++) {
arr2[i] = sc.nextInt();
}

// 3rd Array to store the Sum
int arr3[] = new int[arr1.length];

// Adding arr1 and arr2 and storing into arr3
for (int i = 0; i < arr1.length; i++) {
arr3[i] = arr1[i] + arr2[i];
}

// Print the arr3 elements
for (int i = 0; i < arr3.length; i++) {
System.out.print(arr3[i] + " ");
}

}

}

```

OUTPUT:

Enter the size of the Array:
5
Enter 5 element(s) of the Array1:
1
2
3
4
5
Enter 5 element(s) of the Array2:
1
2
3
4
5
2 4 6 8 10
