Rentable Assignment

For this assignment we will define an interface for items that can be rented. And then define a pair of classes that implement that interface.

Requirements

Create a new Java project called “Rentable”. Inside the project, create five classes:

  1. Define an interface called Rentable the requires the following methods
    • getDescription(); returns the description of the item (return type String)
    • getDailyRate(); returns the daily rate for renting the item (return type double or Double)
    • getPrice(double days); returns the amount due for renting the item for the a given number of days (return type double or Double)

  2. Define a Room class that implements the interface and has a dailyRate variable of type double or Double.

  3. Define a Condo class the implements the interface and has a weeklyRate variable of type double or Double.

  4. Define a Tool class the implements the interface and has an hourlyRate variable of type double or Double.

  5. Create a RentableProgram class that will contain your main method and act as a “driver” for your program. Your main method should:
    • Instantiate a few instances of each of the classes (Room, Condo, Tool), and add them to an array of Rentable objects.
    • Loop through the array, and print out the description and the daily rate for each item.
    • Ask the user for a number of days to generate the final price for each of the items in the array.
