Bicycle demo | PRG421 Java Programming II | University of Phoenix

 

Resources:

  • “Lesson: Object-Oriented Programming Concepts” on The Java™ Tutorials website
  • Downloadable starter code from the Oracle® website: Bicyle class and BicycleDemo class

For this assignment, you will modify existing code to create a single Java™ program named BicycleDemo.java that incorporates the following:

  • An abstract Bicycle class that contains private data relevant to all types of bicycles (cadence, speed, and gear) in addition to one new static variable: bicycleCount. The private data must be made visible via public getter and setter methods; the static variable must be set/manipulated in the Bicycle constructor and made visible via a public getter method.
  • Two concrete classes named MountainBike and RoadBike, both of which derive from the abstract Bicycle class and both of which add their own class-specific data and getter/setter methods.

Read through the “Lesson: Object-Oriented Programming Concepts” on The Java™ Tutorials website.

Download the linked Bicycle class, or cut-and-paste it at the top of a new Java™ project named BicycleDemo.

Download the linked BicycleDemo class, or cut-and-paste it beneath the Bicycle class in the BicycleDemo.java file.

Optionally, review this week’s Individual “Week One Analyze Assignment,” to refresh your understanding of how to code derived classes.

Adapt the Bicycle class by cutting and pasting the class into the NetBeans editor and completing the following:

  • Change the Bicycle class to be an abstract class.
  • Add a private variable of type integer named bicycleCount, and initialize this variable to 0.
  • Change the Bicycle constructor to add 1 to the bicycleCount each time a new object of type Bicycle is created.
  • Add a public getter method to return the current value of bicycleCount.
  • Derive two classes from Bicycle: MountainBike and RoadBike. To the MountainBike class, add the private variables tireTread (String) and mountainRating (int). To the RoadBike class, add the private variable maximumMPH (int).

Using the NetBeans editor, adapt the BicycleDemo class as follows:

  • Create two instances each of MountainBike and RoadBike.
  • Display the value of bicycleCount on the console.

Comment each line of code you add to explain what you added and why. Be sure to include a header comment that includes the name of the program, your name, PRG/421, and the date.
