i. Create an array to hold 15 double values.
double arr[] = new double[15];
ii. Assign the value 10.5 to the last element in the array.
arr[14] = 10.5;
iii. Display the sum of the first and the last element.
double r = arr[0] + arr[14];
System.out.println("Result = " + r);
iv. Write a loop that computes the sum of all elements in the array.
double sum = 0;
for (int i = 0; i < 15; i++) {
sum += arr[i];
}
System.out.println("Sum = " + sum);
