Constructor Detail

Point2D

public Point2D(double x,
       double y)

Creates a new instance of Point2D.

Parameters:

x - the x coordinate of the point

y - the y coordinate of the point

Method Detail

getX

public final double getX()

The x coordinate.

Returns:

the x coordinate

getY

public final double getY()

The y coordinate.

Returns:

the y coordinate

distance

public double distance(double x1,
              double y1)

Computes the distance between this point and point (x1, y1).

Parameters:

x1 - the x coordinate of other point

y1 - the y coordinate of other point

Returns:

the distance between this point and point (x1, y1).

distance

public double distance(Point2D p)

Computes the distance between this point and point p.

Parameters:

p - the other point

Returns:

the distance between this point and point p.

equals

public boolean equals(java.lang.Object obj)

Indicates whether some other object is "equal to" this one.

Overrides:

equals in class java.lang.Object

Parameters:

obj - the reference object with which to compare

Returns:

true if this point is the same as the obj argument; false otherwise

hashCode

public int hashCode()

Returns a hash code value for the point.

Overrides:

hashCode in class java.lang.Object

Returns:

a hash code value for the point.

toString

public java.lang.String toString()

Returns a string representation of this Point2D. This method is intended to be used only for informational purposes. The content and format of the returned string might vary between implementations. The returned string might be empty but cannot be null.

Overrides:

toString in class java.lang.Object
