Java Program to Calculate the Average of an Array

You have given an integer array, Write a Java program to calculate the average of the given array.

Example 1:
Input: arr = {1,2,3,4,5}
Output: 3

Approach 1

First, find the sum of the given array using the loop, then divide the sum by the length of the array.

Java Program: 

// Java program to Calculate Average of an array

public class Main {
	
	public static void main(String[] args) { 
		
		int[] arr = {1,2,3,4,5};
		
		int sum = 0;
		for (int i = 0; i < arr.length; i++) {
			sum += arr[i];
		}
		
		float avg = sum / arr.length;
		System.out.println("The Average of the Array is: " + avg);
	}
}

Output: 

The Average of the Array is: 3.0
