Constructor Details

Triangle

public Triangle(Vector2D p1,
 Vector2D p2,
 Vector2D p3)

Creates an instance of a Triangle record class.

Parameters:

p1 - the value for the p1 record component

p2 - the value for the p2 record component

p3 - the value for the p3 record component

Method Details

contains

public boolean contains(Vector2D point)

Description copied from interface: Shape

Checks if this Shape contains a point.

Specified by:

contains in interface Shape

Parameters:

point - the point to check

Returns:

true if this shape contains the point

getPoints

public Vector2D[] getPoints()

Specified by:

getPoints in interface Shape

Returns:

the array of points making up this shape

getArea

public float getArea()

Description copied from interface: Shape

Calculates the area of this shape and return it.

Specified by:

getArea in interface Shape

Returns:

the area of this shape

toString

public final String toString()

Returns a string representation of this record class. The representation contains the name of the class, followed by the name and value of each of the record components.

Specified by:

toString in class Record

Returns:

a string representation of this object

hashCode

public final int hashCode()

Returns a hash code value for this object. The value is derived from the hash code of each of the record components.

Specified by:

hashCode in class Record

Returns:

a hash code value for this object

equals

public final boolean equals(Object o)

Indicates whether some other object is "equal to" this one. The objects are equal if the other object is of the same class and if all the record components are equal. All components in this record class are compared with Objects::equals(Object,Object).

Specified by:

equals in class Record

Parameters:

o - the object with which to compare

Returns:

true if this object is the same as the o argument; false otherwise.

p1

public Vector2D p1()

Returns the value of the p1 record component.

Returns:

the value of the p1 record component

p2

public Vector2D p2()

Returns the value of the p2 record component.

Returns:

the value of the p2 record component

p3

public Vector2D p3()

Returns the value of the p3 record component.

Returns:

the value of the p3 record component
