public class Point

extends java.lang.Object

A point representing a location in (x, y) coordinate space, specified in integer precision.

Field Summary

int	x The x coordinate.
int	y The y coordinate.

Constructor Summary

Point()
Constructs a default Point with the location (0,0).

Point(int x, int y)
Constructs a new Point at the specified coordinates (x,y).

Point(Point p)
Constructs a Point with the same location as the specified Point p.

Method Summary

boolean	equals(java.lang.Object obj) Determines whether two points are equal.
void	move(int x, int y) Move this Point to the specified coordinates.
static Point	parsePoint(java.lang.String s) Parses a String representation of a Point object.
java.lang.String	toString() Returns a string representation of this point and its location in the (x, y) coordinate space.

Field Detail

x

public int x

The x coordinate.

y

public int y

The y coordinate.

Constructor Detail

Point

public Point()

Constructs a default Point with the location (0,0).

Point

public Point(Point p)

Constructs a Point with the same location as the specified Point p.

Parameters:

p - the Point to initialize the new Point with.

Point

public Point(int x,
             int y)

Constructs a new Point at the specified coordinates (x,y).

Parameters:

x - the x coordinate.

y - the y coordinate.

Method Detail

move

public void move(int x,
                 int y)

Move this Point to the specified coordinates.

Parameters:

x - the new x coordinate.

y - the new y coordinate.

translate

public void translate(int x,
                      int y)

Translate this Point by the specified values.

Parameters:

x - the amount to translate the x coordinate of the Point.

y - the amount to translate the y coordinate of the Point.

equals

public boolean equals(java.lang.Object obj)

Determines whether two points are equal. Two instances of Point are equal if the values of their x and y member fields, representing their position in the coordinate space, are the same.

Overrides:

equals in class java.lang.Object

Parameters:

obj - the object to compare with.

Returns:

true if obj is a Point and has the same coordinates as this Point, false otherwise.

toString

public java.lang.String toString()

Returns a string representation of this point and its location in the (x, y) coordinate space. The String is the x and y coordinates separated by a comma.

Overrides:

toString in class java.lang.Object

Returns:

a String representation of this object.

parsePoint

public static Point parsePoint(java.lang.String s)

Parses a String representation of a Point object. A valid string is a comma-separated pair of values representing the x and y elements of the object. E.G. "4,6".

Parameters:

s - the String to parse.

Returns:

the Point represented by the String s, or null if the String is invalid.
