• Inside the findMaxElement method, we iterate through the array elements and update the max variable if we
encounter a larger element.
• The maximum element is returned and stored in the max variable in the main method.

• Finally, we print the maximum element to the console.

TASK 3: Calculating the Sum of Array Elements
public class SumArrayDemo {
public static void main(String[] args) {
double[] values = {2.5, 3.0, 4.5, 1.5, 2.0};

// Calling the method to calculate the sum of array elements
double sum = calculateSum(values);
System.out.println(“Sum of array elements: “ + sum);
}

// Method to calculate the sum of array elements
public static double calculateSum(double[] arr) {
double sum = 0;
for (double value : arr) {
sum += value;
}

return sum;
}
}
Output:

Explanation:
• In this program, we define a method calculateSum that takes an array of doubles as a parameter and returns
the sum of the array elements.
• We declare an array values containing double values in the main method.
• We call the calculateSum method and pass the values array as an argument.
• Inside the calculateSum method, we iterate through the array elements and accumulate their sum in the sum
variable.
