The X coordinate of this Point
.
If no X coordinate is set it will default to 0.@serial
The Y coordinate of this Point
.
If no Y coordinate is set it will default to 0.@serial
Constructs and initializes a point at the origin (0, 0) of the coordinate space.
Constructs and initializes a point with the same location as
the specified Point
object.
p | a point |
---|
Constructs and initializes a point at the specified
(x,y)
location in the coordinate space.
x | the X coordinate of the newly constructed Point |
---|---|
y | the Y coordinate of the newly constructed Point |
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.
obj | an object to be compared with this Point2D |
---|
true
if the object to be compared is
an instance of Point2D
and has
the same values; false
otherwise.
Returns the location of this point.
This method is included for completeness, to parallel the
getLocation
method of Component
.
Returns the X coordinate of this Point2D
in
double
precision.
Point2D
.Returns the Y coordinate of this Point2D
in
double
precision.
Point2D
.Moves this point to the specified location in the
(x,y)
coordinate plane. This method
is identical with setLocation(int, int)
.
x | the X coordinate of the new location |
---|---|
y | the Y coordinate of the new location |
Sets the location of the point to the specified location.
This method is included for completeness, to parallel the
setLocation
method of Component
.
p | a point, the new location for this point |
---|
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)
.
x | the X coordinate of the new location |
---|---|
y | the Y coordinate of the new location |
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
.
x | the X coordinate of the new location |
---|---|
y | the Y coordinate of the new location |
Returns a string representation of this point and its location
in the (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
.
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)
.
dx | the distance to move this point along the X axis |
---|---|
dy | the distance to move this point along the Y axis |
