Constructor Detail

Triangle

public Triangle(Point a,
                Point b,
                Point c)

Initializes a newly created Triangle object. The class description goes into more detail about the Points.

Parameters:

a - the initial value of Point a

b - the initial value of Point b

c - the initial value of Point c

Method Detail

getSide1

public double getSide1()

The length of the first side of the triangle. Use the class description to determine which points to use.

Returns:

the length of side1

getSide2

public double getSide2()

The length of the second side of the triangle. Use the class description to determine which points to use.

Returns:

the length of side2

getSide3

public double getSide3()

The length of the third side of the triangle. Use the class description to determine which points to use.

Returns:

the length of side3

calculateArea

public double calculateArea()

Calculate the area of the triangle.

Specified by:

calculateArea in class Shape

Returns:

the area of the triangle

calculatePerimeter

public double calculatePerimeter()

Calculate the perimeter of the triangle.

Specified by:

calculatePerimeter in class Shape

Returns:

the perimeter of the triangle

equals

public boolean equals(java.lang.Object o)

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

Returns:

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

hashCode

public int hashCode()

hashCode autogenerated using IntelliJ. Note the use of a prime number.

Overrides:

hashCode in class java.lang.Object

Returns:

hashcode for the Triangle class.
