coordinate space,
specified in integer precision.Modifier and Type | Field and Description |
---|---|
int |
x
The X coordinate of this
Point . |
int |
y
The Y coordinate of this
Point . |
Constructor and Description |
---|
Point()
Constructs and initializes a point at the origin
(0, 0) of the coordinate space.
|
Point(int x,
int y)
Constructs and initializes a point at the specified
(x,y) location in the coordinate space. |
Point(Point p)
Constructs and initializes a point with the same location as
the specified
Point object. |
Modifier and Type | Method and Description |
---|---|
boolean |
equals(java.lang.Object obj)
Determines whether or not two points are equal.
|
Point |
getLocation()
Returns the location of this point.
|
double |
getX()
Returns the X coordinate of this
Point2D in
double precision. |
double |
getY()
Returns the Y coordinate of this
Point2D in
double precision. |
void |
move(int x,
int y)
Moves this point to the specified location in the
(x,y) coordinate plane. |
void |
setLocation(double x,
double y)
Sets the location of this point to the specified double coordinates.
|
void |
setLocation(int x,
int y)
Changes the point to have the specified location.
|
void |
setLocation(Point p)
Sets the location of the point to the specified location.
|
java.lang.String |
toString()
Returns a string representation of this point and its location
in the
(x,y) coordinate space. |
void |
translate(int dx,
int dy)
Translates this point, at location
(x,y) ,
by dx along the x axis and dy
along the y axis so that it now represents the point
(x+dx,y+dy) . |
