public class Rectangle
extends Shape

Content originated from Kushagra Tiwary, 10/30/2016 Modified by garethhalladay on 9/12/17 Use point1.distance(point2) to find the distance between two Point objects. You can assume that the distance between a and d is the same as the distance between b and c and that the distance between a and b is the same as the distance between c and d. The length is defined as the distance between a and d or the distance between b and c.
The width is defined as the distance between a and b or the distance between c and d.

Constructor Detail

Rectangle

public Rectangle(Point a,
                 Point b,
                 Point c,
                 Point d)

Initializes a newly created Rectangle object. The class description goes into further details about preconditions for the points.

Parameters:

a - initial value for Point a

b - initial value for Point b

c - initial value for Point c

d - initial value for Point d

Method Detail

getWidth

public double getWidth()

Calculates the width of the rectangle. Read the description about the class to determine which points to use for this calculation

Returns:

the width of the rectangle

getLength

public double getLength()

Calculates the length of the rectangle. Read the description about the class to determine which points to use for this calculation

Returns:

the length of the rectangle

calculateArea

public double calculateArea()

Calculates the area of the rectangle.

Specified by:

calculateArea in class Shape

Returns:

the area of the rectangle.

calculatePerimeter

public double calculatePerimeter()

Calculates the perimeter of the rectangle.

Specified by:

calculatePerimeter in class Shape

Returns:

the perimeter of the rectangle.

equals

public boolean equals(java.lang.Object o)

Compares this rectangle to a specified object. The result is true if and only if the argument is not null and is a Rectangle object that represents the same sequence of Points as this object.

Overrides:

equals in class java.lang.Object

Parameters:

o - the object to compare the rectangle against

Returns:

true if the given object represents a rectangle equivalent to this rectangle, false otherwise

hashCode

public int hashCode()

hashCode auto-generated using intelliJ. Note the use of a prime number.

Overrides:

hashCode in class java.lang.Object

Returns:

hashCode for the Rectangle class.
