Chapter 5, Problem 10AW
Write a method named quartersToDol1ars. The method should accept an int argument that is a number of quarters, and return the equivalent number of dollars as a double. For example, if you pass 4 as an argument, the method should return 1.0; and if you pass 7 as an argument, the method should return 1.75.

QUESTION 2
A prime number is a number that is evenly divisible only by itself and 1. For example, the
number 5 is prime because it can be evenly divided only by 1 and 5. The number 6, however,
is not prime because it can be divided evenly by 1, 2, 3, and 6.
Write a method named isPrime, which takes an integer as an argument and returns true if
the argument is a prime number, or false otherwise. Demonstrate the method in a complete
program.
Tip: Recall that the % operator divides one number by another, and returns the remainder
of the division. In an expression such as num1 % num2, the % operator will return 0 if
num1 is evenly divisible by num2.
QUESTION 3
Use the isPrime method that you wrote in previous question in a program that
stores a list of all the prime numbers from 1 through 100 in a file.

In java A Carpet Company has asked you to write an application that calculates the price of carpeting for rectangular rooms in a building.
To calculate the price, you multiply the area of the floor (width * length) by the price per square foot of carpet. For example, the area of floor that is 12 feet long and 10 feet wide is 120 square feet. To cover that floor with carpet that costs 300 per square foot would cost (12 * 10 * 300 = 36000.)
First, you should create a class named RoomDimension that has two attributes: one for the length of the room and one for the width.
Provide getters/setters, parameterized constructor and a toString method.
The RoomDimension class should also have a member function that returns the area of the room.
Once you have written the class, use in a test application that asks the user to enter the number of rooms in building create array of that size, then ask user to enter dimensions for each room, also ask user for price per square foot of the desired…
