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

a. Prompt the user to input two integers: firstNum and secondNum.

(firstNum must be less than secondNum.)

b. Output all the odd numbers between firstNum and secondNum

inclusive.

c. Output the sum of all the even numbers between firstNum and

secondNum inclusive.

d. Output all the numbers and their squares between 1 and 10.

e. Output the sum of the squares of all the odd numbers between

firstNum and secondNum inclusive.

f. Output all the uppercase letters.

10. Redo Exercise 9 using for loops.

11. Redo Exercise 9 using do...while loops.

Problem description Caf´e Wafflelicious, as its very name signifies, is a cafe that sells waffles. When customers arrive at this cafe, they design the waffle they want according to the kinds of waffles, their ingredients and their prices. The waitress delivers these orders to the cook from the customer. The cook is responsible for making the waffle. You will prepare an order system in which you will check the company’s waffle orders.For example, there is a waffle order from the customer. You need to expand the functionality of the class in a transparent and dynamic way.Waffle Types (Concrete component): Normal Waffle - $13.0 Belgian Waffle - $16.0 Wrap Waffle - $13.0 Wheat Waffle - $15.0 1 Free Gluten Waffle - $17.0 Toppings (Concrete decorator): chocolate - $2.0 for each (white, milky, dark, nutella and caramel) fruits - $0.5 for each (strawberry, kiwi, pineapple and banana) sauces - $1.0 for each (chocolate, caramel and raspberry) nuts - $1.0 for each (pistachio, almond, hazelnut and walnut)

Using any loop of your choice create a program that will prompts the user for two numbers and do calculations as follows, starting from the smallest number add the next number if its even or subtract it if its odd, repeat this until you get to the last number. i.e. if you start at 2 to 4, then 2 – 3 + 4( - because 3 is odd and + because 4 is even)

. Write a Java program that calculates the multiplication table (up to 10) of the randomly generated number (between 1 and 100), and displays that on the screen.

Hint: Math function and For loop.
