Shape

Motivation

Experience implementing interfaces.

Mistakes To Avoid

Warning: Do NOT Parallelize

Code to Investigate

Shape

package shape.core;

public interface Shape {
	double area();
}

Code to Implement

Rectangle

public class Rectangle implements Shape

class:	Rectangle.java
methods:	constructor area() getX() getY() getWidth() getHeight() area()
package:	shape.warmup
source folder:	student/src/main/java

constructor

method: public Rectangle(double x, double y, double width, double height) (sequential implementation only)

getX()

method: public double getX() (sequential implementation only)

getY()

method: public double getY() (sequential implementation only)

getWidth()

method: public double getWidth() (sequential implementation only)

getHeight()

method: public double getHeight() (sequential implementation only)

area()

method: public double area() (sequential implementation only)

Circle

public class Circle implements Shape

class:	Circle.java
methods:	constructor area() getX() getY() getRadius() area()
package:	shape.warmup
source folder:	student/src/main/java

constructor

method: public Circle(double x, double y, double radius) (sequential implementation only)

getX()

method: public double getX() (sequential implementation only)

getY()

method: public double getY() (sequential implementation only)

getRadius()

method: public double getRadius() (sequential implementation only)

area()

method: public double area() (sequential implementation only)
