Lab Report Questions
Is it possible to create an instance of an interface?
How many classes can any class inherit? How many interfaces can a class implement?
Objective:
Write a class that uses the shape interface to now draw a diamond
First download the driver and put it in your project
DO NOT ALTER THE DRIVER!
Also download the ShapeBasics and ShapeInterface to use in your code
Write an INTERFACE called DiamondInterface which inherits from ShapeInterface
Create the following method definitions
setWidth this method is used to set the width of the diamond
Write a class file called Diamond that DOES NOT HAVE a main method
This class implements the DiamondInterface and inherits from ShapeBasics
Some of the attributes of Diamond are
width that represents the width of the triangle that has to be odd
Create the following ConstructorsDefault sets everything to default values
width = 0
One that has the parameters
Offset used in the parent class
width
Accessors and Mutators for each variable
MAKE SURE THE MUTATORS CHECK FOR VALID VALUES!
Create the following Methods
setWidth this sets the width of the diamond. This must be implemented just like the interface. This number must be odd.
drawHere this draws the diamond and overrides the method in ShapeBasics
drawTopV this private method draws the top part of the diamond
drawBottomV this private method draws the bottom part of the diamond
Create the following static methods
skipSpaces this takes in a certain number of spaces to skip which means drawing .
Example Dialog:
Welcome to the diamond drawer
Enter the diamond size followed by the offset or 0 to quit
