coordinate space, specified in integer precision.Point2D.Double, Point2D.Float
Modifier and Type | Field | Description |
---|---|---|
int |
x |
The X coordinate of this Point . |
int |
y |
The Y coordinate of this Point . |
Constructor | Description |
---|---|
Point() |
Constructs and initializes a point at the origin (0, 0) of the coordinate space. |
Point |
Constructs and initializes a point at the specified (x,y) location in the coordinate space. |
Point |
Constructs and initializes a point with the same location as the specified Point object. |
Modifier and Type | Method | Description |
---|---|---|
boolean |
equals |
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 |
Moves this point to the specified location in the (x,y) coordinate plane. |
void |
setLocation |
Sets the location of this point to the specified double coordinates. |
void |
setLocation |
Changes the point to have the specified location. |
void |
setLocation |
Sets the location of the point to the specified location. |
String |
toString() |
Returns a string representation of this point and its location in the (x,y) coordinate space. |
void |
translate |
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) . |

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

, and any number larger than Integer.MAX_VALUE
will be reset to MAX_VALUE
