Overview
For this semester, you will be doing a number of labs and projects using the same class over and over again. You’ll be using it for labs/projects like a linked list of objects, stack of objects, queue of objects, tree of objects. Some of the projects will be like maintaining a database of objects where you will interact with the user to add, update, and delete from the database.
Instead of you being forced to do a specific class, you can create your own class as long as it isn’t a Rectangle, Cube, Car, Coin, or Circle (or Butt)
The class you create must have at least 2 attributes, you need at least 1 constructor that will receive at least 1 parameter, you need setters and getters for each of the fields where applicable *remember how the Car class had a getSpeed() but didn’t have a setSpeed() - it had brake() and accelerate() ]
If you can’t think of a good class and are lost as to what to do, here is an example:
Cheese class with attributes a String of cheeseType and a double of cheesePrice. The constructor would receive parameters newCheeseType and newCheesePrice. The methods would be getCheeseType(), getCheesePrice(), setCheeseType(), setCheesePrice()
Project Details
For this review project, you are to create a Class of your own choosing (other than Rectangle / Cube / Car / Coin / Circle / Butt) and use that class
You are to:
? prompt the user for the attributes (Scanner or JOptionPane)
? create the object in memory using the user’s input
? Display the attributes from the object using the getters.
A Sample Run (using Cheese class):
Enter the type of cheese: Cheddar
Enter the price of the cheese: 1.99
Cheese type: Cheddar
Cheese price: 1.99
Press any key to continue . . .
