Constructor Detail

Point2D

public Point2D()

Constructs and initializes a Point initialized with (0, 0, 0).

Point2D

public Point2D(Point2D p)

Constructs and initializes a Point with the same location as the specified Point2D.

Parameters:

p - a point in 2D space

Point2D

public Point2D(double x,
               double y)

Constructs and initializes a Point from the specified x, y, and z coordinates.

Parameters:

x - the x coordinate

y - the y coordinate

Method Detail

distance

public double distance(Point2D p)

Calculates the distance between this Point2D and the specified Point2D.

Parameters:

p - the specified Point2D

equals

public boolean equals(java.lang.Object obj)

Checks whether two pointers are equal.

Overrides:

equals in class java.lang.Object

getLocation

public Point2D getLocation()

hashCode

Returns the hashcode for this Point2D.

Overrides:

hashCode in class java.lang.Object

move

public void move(double x,
                 double y)

Changes the point to have the specified location.

Parameters:

x - the x coordinate of the new location

y - the y coordinate of the new location

setLocation

public void setLocation(Point2D p)

Changes the point to have the specificed location. This method is included for completeness, to parallel the setLocation method of Component.

Parameters:

Parameters:

x - the x coordinate of the new location

y - the y coordinate of the new location

toString

public java.lang.String toString()

Returns the String representation of this Point's coordinates.

Overrides:

toString in class java.lang.Object

translate

public void translate(int x,
                      int y)

Translates the 2D point.
