The y coordinate. |
Constructor Summary | |
---|---|
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. |
Method Summary | |
---|---|
boolean |
equals(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 the point in double precision. |
double |
getY()
Returns the Y coordinate of the point 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. |
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 ). |
