Constructor Detail

Circle

public Circle(Point a,
              Point b)

Initializes a newly created Circle object whose location and size are determined by Point a and and Point b

Parameters:

a - center point of the circle

b - point on the diameter of the circle

Method Detail

getRadius

public double getRadius()

Calculates the radius of the circle.

Returns:

the radius

calculateArea

public double calculateArea()

Calculates the area of a circle.

Specified by:

calculateArea in class Shape

Returns:

the area of a circle.

calculatePerimeter

public double calculatePerimeter()

Calculates the perimeter of a circle.

Specified by:

calculatePerimeter in class Shape

Returns:

the perimeter of a circle

equals

public boolean equals(java.lang.Object o)

Compares this circle to a specified object. The result is true if and only if the argument is not null and is a Circle 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 circle against

Returns:

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

hashCode

public int hashCode()

Auto-generated hashcode using intelliJ. Note the use of a prime number.

Overrides:

hashCode in class java.lang.Object

Returns:

hashcode for the Circle class
