Sammy's Seashore Supplies rents beach equipment such as kayaks, canoes, beach chairs, and umbrellas to tourists. In Chapter 3, you created a Rental class for the company. The Rental class contains two public final static fields that hold the number of minutes in an hour and the hourly rental rate ($40), and four private fields that hold a contract number, number of hours for the rental, number of minutes over an hour, and the price. It also contains two public set methods and four public get methods. Now, modify the Rental class to contain two overloaded constructors. One constructor accepts a contract number and number of minutes as parameters. Pass these values to the setContractNumber() and setHoursAndMinutes() methods, respectively. The setHoursAndMinutes() method will automatically calculate the hours, extra minutes, and price. The other constructor is a default constructor that passes "A000" and 0 to the two-parameter constructor. Save the file as Rental.java. b. In Chapter 3, you also created a RentalDemo class to demonstrate a Rental object. Now, modify that class to instantiate two Rental objects. Instantiate one object to retain the constructor default values. Accept user data for the contract number and minutes fields and use this data set to instantiate the second object. Display all the details for both objects.
OOPs
In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career.
Constructor
The easiest way to think of a constructor in object-oriented programming (OOP) languages is:

It also contains two public set methods and four public get methods.
Now, modify the Rental class to contain two overloaded constructors.
- One constructor accepts a contract number and number of minutes as parameters. Pass these values to the setContractNumber() and setHoursAndMinutes() methods, respectively. The setHoursAndMinutes() method will automatically calculate the hours, extra minutes, and price.
- The other constructor is a default constructor that passes "A000" and 0 to the two-parameter constructor.
Save the file as Rental.java.
b. In Chapter 3, you also created a RentalDemo class to demonstrate a Rental object. Now, modify that class to instantiate two Rental objects.
- Instantiate one object to retain the constructor default values.
- Accept user data for the contract number and minutes fields and use this data set to instantiate the second object. Display all the details for both objects.
Save the file as RentalDemo.java.
Create a zip file of the .java file(s) and submit the assignment.
