private Point p2

Point representing the second endpoint for the line segment

Constructor Detail

LineSegment

public LineSegment(Point p1,
                   Point p2)

Constructor that accepts the two endpoints of the line segment. Since the LineSegment class extends the Line class, you must have a call to the super constructor at the beginning of this constructor.

Parameters:

p1 - Point representing one endpoint of the line segment

p2 - Point representing the other endpoint of the line segment

Method Detail

getP1

public Point getP1()

Getter for the first endpoint

Returns:

A Point representing the first endpoint of the line segment

setP1

public void setP1(Point p1)

Setter to change the first endpoint

Parameters:

p1 - A Point representing the new first enpoint of the line segment

getP2

public Point getP2()

Getter for the second endpoint

Returns:

A Point representing the second endpoint of the line segment

setP2

public void setP2(Point p2)

Setter to change the first endpoint

Parameters:

p1 - A Point representing the new first enpoint of the line segment

equals

public boolean equals(java.lang.Object object)

Method to compare 'this' line segment for equality with the 'object' specified as a parameter.

Overrides:

equals in class Line

Parameters:

An - Object to be tested for equality with 'this' line segment

Returns:

Returns true if the specified 'object' is a LineSegment with the same endpoints as 'this' LineSegment. Returns false otherwise.
