# Java: Calculate the average value of array elements

## Java Array: Exercise-4 with Solution

Write a Java program to calculate the average value of array elements.

Pictorial Presentation:

Sample Solution:

Java Code:

// Define a class named Exercise4.
public class Exercise4 {
// The main method where the program execution starts.
public static void main(String[] args) {
// Declare an integer array 'numbers' and initialize it with values.
int[] numbers = new int[]{20, 30, 25, 35, -16, 60, -100};

// Initialize a variable 'sum' to store the sum of array elements.
int sum = 0;

// Use a for loop to iterate over the elements of the 'numbers' array.
for (int i = 0; i < numbers.length; i++) {
// Add the current element to the sum.
sum = sum + numbers[i];
}

// Calculate the average value by dividing the sum by the number of elements.
double average = sum / numbers.length;

// Print the calculated average value to the console.
System.out.println("Average value of the array elements is : " + average);
}
}

Sample Output:

Average value of the array elements is : 7.0
