Array Average Calculation
This program calculates the average of array elements.
Problem Statement
Write a Java program to calculate the average of elements in an integer array.
Source Code
| 1 | public class ArrayAverage { |
| 2 | public static void main(String[] args) { |
| 3 | int[] arr = {10, 20, 30, 40, 50}; |
| 4 | int sum = 0; |
| 5 | for(int i=0; i<arr.length; i++) { |
| 6 | sum += arr[i]; |
| 7 | } |
| 8 | double avg = (double)sum / arr.length; |
| 9 | System.out.println("Average of array elements: " + avg); |
| 10 | } |
| 11 | } |
Program Output
Average of array elements: 30.0
Explanation
The variable sum accumulates all elements, and the average is calculated by dividing sum by arr.length with a type cast to double ensuring decimal precision, together demonstrating average calculation using arrays.
