In this task, you are being asked to write a loop in Java.

Write a program that uses while loops to perform the following steps:

a) Prompt the user to input two integers: startingNum and endingNum (startingNum must be

less than endingNum).

b) Output all even numbers between startingNum and endingNum.

c) Output the sum of all even numbers between startingNum and endingNum.

d) Output the numbers and their squares between startingNum and endingNum.

e) Output the sum of the square of the odd numbers between startingNum and endingNum.

1. Create a program called WhileLoops.java. All loops will be written in this file.

2. Create appropriate variables and assign values using a Scanner object.

3. Correctly display appropriate messages.
