Class Coord

java.lang.Object
  pzapplet.Coord

public class Coord

extends java.lang.Object

This class represents a coordinate in a cartesian plane. The coordinate has an x value and y value, which is normally written as (x, y). This class provides a method for finding if Coord's are within a specified range of each other and finding the reflected point over the X axis.

Constructor Detail

Coord

public Coord(int x,
             int y)

Parameters:

x - - x value of the new Coord

y - - y value of the new Coord Creates a Coord object that represents a coordinate in a cartesian plane (x, y).

Method Detail

getX

public int getX()

Returns:

int x - The x value of this

getY

public int getY()

Returns:

int y - The y value of this

withinRangeOf

public boolean withinRangeOf(Coord arg,
                             int range)

Parameters:

arg - - The coord to compare to this

range - - The distance allowed between the two Coords

Returns:

true if the x and y values of each Coord are independently within the value of range

equals

public boolean equals(Coord arg)

Parameters:

arg - - the Coord to compare to this

Returns:

true if the two Coord's refer to the same point

getOpp

public Coord getOpp(int height)

Parameters:

height - - the offset from the measurement of the x-axis to the 0 of the drawing plane.

Returns:

a new Coord that has the same x value, but a y-value that is the opposite of this

toString

public java.lang.String toString()
