Field Detail

x

public int x
The X coordinate of this Point. If no X coordinate is set it will default to 0.

y

public int y
The Y coordinate of this Point. If no Y coordinate is set it will default to 0.
Constructor Detail

Point

public Point()
Constructs and initializes a point at the origin (0, 0) of the coordinate space.


Point

public Point(int x,
             int y)
Constructs and initializes a point at the specified {@code (x,y)} location in the coordinate space.

Parameters:
x - the X coordinate of the newly constructed Point
y - the Y coordinate of the newly constructed Point

Point

public Point(Point p)
Constructs and initializes a point with the same location as the specified Point object.

Parameters:
p - a point
Method Detail

equals

public boolean equals(Object obj)
Determines whether or not two points are equal. Two instances of Point2D 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 Point2D
Parameters:
obj - an object to be compared with this Point2D
Returns:
true if the object to be compared is an instance of Point2D and has the same values; false otherwise.

getLocation

public Point getLocation()
Returns the location of this point. This method is included for completeness, to parallel the getLocation method of Component.

Returns:
a copy of this point, at the same location

getX

public double getX()
{@inheritDoc}

Overrides:
getX in class Point2D

getY

public double getY()
{@inheritDoc}

Overrides:
getY in class Point2D

move

public void move(int x,
                 int y)
Moves this point to the specified location in the {@code (x,y)} coordinate plane. This method is identical with setLocation(int, int).

Parameters:
x - the X coordinate of the new location
y - the Y coordinate of the new location

setLocation

public void setLocation(double x,
                        double y)
Sets the location of this point to the specified double coordinates. The double values will be rounded to integer values. Any number smaller than Integer.MIN_VALUE will be reset to MIN_VALUE, and any number larger than Integer.MAX_VALUE will be reset to MAX_VALUE.

Overrides:
setLocation in class Point2D
Parameters:
x - the X coordinate of the new location
y - the Y coordinate of the new location

setLocation

public void setLocation(int x,
                        int y)
Changes the point to have the specified location.

This method is included for completeness, to parallel the setLocation method of Component. Its behavior is identical with move(int, int).

Parameters:
x - the X coordinate of the new location
y - the Y coordinate of the new location

setLocation

public void setLocation(Point p)
Sets the location of the point to the specified location. This method is included for completeness, to parallel the setLocation method of Component.

Parameters:
p - a point, the new location for this point

toString

public String toString()
Returns a string representation of this point and its location in the {@code (x,y)} coordinate space. This method is intended to be used only for debugging purposes, and the content and format of the returned string may vary between implementations. The returned string may be empty but may not be null.

Overrides:
toString in class Object
Returns:
a string representation of this point

translate

public void translate(int dx,
                      int dy)
Translates this point, at location {@code (x,y)}, by {@code dx} along the {@code x} axis and {@code dy} along the {@code y} axis so that it now represents the point {@code (x+dx,y+dy)}.

Parameters:
dx - the distance to move this point along the X axis
dy - the distance to move this point along the Y axis
