Question

You have been assigned to a development team that is building software that will be used to control the operations of a bicycle rental store. A rental store has a limited number of vehicles that can be managed. A bicycle rental store must maintain information about how many vehicles are available for rental. The bicycle rental store must provide publicly available methods to allow vehicles to be added and removed from it. The rental store should also provide publicly available methods that reports its capacity. An attempt to add or remove the vehicle other than it’s capacity should print the message letting user know that he/she can’t add or delete the vehicle (Hint: use “if” condition to check the number of vehicles. They shouldn’t be more that 5/5 each to add and less than 1 to delete). At the moment there are two distinct types of vehicles: bicycle and quadricycle (four-wheel bicycle). Every vehicle has a company code, a fun name, number of wheels and a rental price. The bicycle has two wheels whereas quadricycle has four. Define the Java classes that are required to implement the functionality that is described above. Be sure to use object-oriented principles in your Java code. Hints • Vehicle class, Bicycle class, Quadricycle class, RentalStore class. • Bicycle class and Quadricycle class inherits extends from Vehicle class • RentalStore class will have methods to show the total number of vehicles, add/delete Bicycle and add/delete Quadricycle • Rental class should have ArrayList • In general every class should have attributes, constructor and it’s methods. • Besides RentalStore class, all other classes should have toString() method . • Create TestClass that have Main() method. Bicycles: company code 0001, a fun name ( your choice), number of wheels : 2 and a rental price 150 company code 0002, a fun name ( your choice), number of wheels : 2 and a rental price 110 company code 0003, a fun name ( your choice), number of wheels : 2 and a rental price 50 company code 0004, a fun name ( your choice), number of wheels : 2 and a rental price 250 company code 0005, a fun name ( your choice), number of wheels : 2 and a rental price 90 quadricycle : company code 0011, a fun name ( your choice), number of wheels : 4 and a rental price 250 company code 0012, a fun name ( your choice), number of wheels : 4 and a rental price 110 company code 0013, a fun name ( your choice), number of wheels : 4 and a rental price 210 company code 0014, a fun name ( your choice), number of wheels : 4 and a rental price 210 company code 0015, a fun name ( your choice), number of wheels : 4 and a rental price 190 For this scenario, we will have 5 bicycles and 5 quadricycles (total of 10 vehicles). Add all those vehicles to an ArrayList. Find bicycles with price less than $100 and delete all of them. Find quadricycles with price less than $200 and delete all of them. At last, show to total number of remaining vehicles with their details.
