Position2D

public Position2D(double x,
                  double y)

Creates a new Position object.

Method Detail

getX

public double getX()

Returns the x coordinate of this position.

getY

public double getY()

Returns the y coordinate of this position.

setX

public void setX(double newx)

Sets the x coordinate of this position.

setY

public void setY(double newy)

Sets the y coordinate of this position.

distanceTo

public double distanceTo(Position position)

Returns the distance from this position to position (i.e. the L2-Norm of the positions). The argument is expected to be another instance of Position2D.

Specified by:

distanceTo in class Position
