room. Assume that the room has one door, two windows, and one bookshelf. Your program must do the following:
a. Prompts the user to enter, in feet, the length, width, and height of a
room. Read the dimensions of the room.
b. Prompts the user to enter the widths and heights, in feet, of the door,
each window, and the bookshelf. Read these quantities.
c. Prompts the user to enter the cost, per square foot, of painting the
walls. Read these quantities.
d. Prompts the user to enter of cost, per square foot, of installing carpet.

. To make a profit, a local store marks up the prices of its items by a certain
percentage. Write a Java program that reads the original price of the item

the sales tax, and the final price of the item. (The final price of the item is
the selling price plus the sales tax.)

A parking garage charges a $2.00 minimum fee to park for up to three hours. The garage charges an additional $0.50 per hour for each hour or part thereof in excess of three hours. The maximum charge for any given 24-hour period is $10.00. Assume that no car parks for longer than 24 hours at a time. Write an application that calculates and displays the parking charges for each customer who parked in the garage yesterday. You should enter the hours parked for each customer. The program should display the charge for the current customer and should calculate and display the running total of yesterday’s receipts. It should use the method calculateCharges to determine the charge for each customer.
