 In this post, we will write a Java program to print the sum of all the elements of the array.

Java Program to print the sum of all the elements of the array

Write a Java program to find the sum of all the elements of the given integer array.

Example 1:
Input: [1, 2, 3, 4, 5]
Output: 15
Explanation: Sum of all the elements is = 1 + 2 + 3 + 4 + 5 = 15

Approach 1

Using loop we can find the sum of array elements.

Java Program: 

// print sum of all the elements of the array java program

public class Main {
	
	public static int findSum(int[] nums) {
		int sum = 0;
		// Iterate using loop
		for(int i = 0; i < nums.length; i++) {
			sum = sum + nums[i];
		}
		return sum;
	}
	
	public static void main(String[] args) { 
		int[] arr = {1, 4, 7, 9, 10};
		int sum = findSum(arr);
		System.out.println("Sum of all the elements is: " + sum);
	}
}
