Instructions
The purpose of this exercise is to create an image like the example below:
You will need to do the following:
- Copy the code in the usage to your
Main.java
You'll define the logic for creating and working with shapes in the geometrical_shapes package. Create the following interfaces:
-
Drawable which contains the methods draw and getColor.
-
Displayable which contains the methods display and save.
Define them according to the way they are called in the Main.java function.
In order to compile and run Main.java
, you'll need to define some classes. You are free to implement all the shapes with whatever internal structure you see fit, but you must provide a constructor for all the shapes, which will be described below:
Point
: a new point should be created from two int values.Line
: a new line should be created from references to two different points.Triangle
: a new triangle should be created from references to three different points.Rectangle
: a new rectangle should be created from references to two different points.Circle
: a new circle should be created from a reference to a point representing the center, and an int value representing the circle's radius.
You'll also need to create the random
method for Line
, Point
, and Circle
. You should derive their signatures from the usage.
Bonus
You may optionally implement the following shapes, including the classes and interfaces needed to draw them:
- Pentagon
- Cube
Usage
interface Displayable {
void display(int x, int y, Color color);
void save(String string);
}
interface Drawable {
void draw(Displayable displayable);
Color getColor();
}
public class Main {
public static void main(String[] args) {
Image image = new Image(1000, 1000);
Rectangle rectangle = new Rectangle(new Point(50, 50), new Point(300, 200));
rectangle.draw(image);
Triangle triangle = new Triangle(new Point(100, 100), new Point(900, 900), new Point(100, 900));
triangle.draw(image);
for (int i = 0; i < 50; i++) {
Circle circle = Circle.random(image.getWidth(), image.getHeight());
circle.draw(image);
}
image.save("image.png");
}
}
