Problem: Create a base class called Vehicle that has the manufacturer’s name (type String), number of cylinders in the engine (type int), and the owner (type Person). Use the Person class developed this semester. Create a class automobile that is derived from Vehicle and has additional properties: number of passengers (type int) and weight in tons (type double). Create a class Truck which is derived from Vehicle and has additional properties: the load capacity in tons (type double, since it may contain a fractional part) and towing capacity in tons (type double). The classes should have: Two constructors, a default and an overloaded constructor All appropriate accessor and mutator methods (getters and setters). An ‘equals’ method (must conform to the Person example and the Object class ). A ‘toString’ method A ‘copy’ constructor A ‘clone’ method A ‘finalize’ method Write a driver (client/test) class that tests ALL the methods. Be sure to invoke each of the constructors, and ALL methods. Demonstrate polymorphism by creating an array of various types of vehicles with varying property values.
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:
Problem: Create a base class called Vehicle that has the manufacturer’s name (type
String), number of cylinders in the engine (type int), and the owner (type Person). Use the
Person class developed this semester. Create a class automobile that is derived from
Vehicle and has additional properties: number of passengers (type int) and weight in tons
(type double). Create a class Truck which is derived from Vehicle and has additional
properties: the load capacity in tons (type double, since it may contain a fractional part)
and towing capacity in tons (type double). The classes should have:
- Two constructors, a default and an overloaded constructor
- All appropriate accessor and mutator methods (getters and setters).
- An ‘equals’ method (must conform to the Person example and the Object class ).
- A ‘toString’ method
- A ‘copy’ constructor
- A ‘clone’ method
- A ‘finalize’ method
Write a driver (client/test) class that tests ALL the methods. Be sure to invoke each of the
constructors, and ALL methods. Demonstrate polymorphism by creating an array of
various types of vehicles with varying property values.
