getLocation()
,move(int, int)
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.
 Since:
 1.1
Point
public Point(Point p)
Constructs and initializes a point with the same location as the specified Point
object.
 Parameters:

p
 a point  Since:
 1.1
Point
public Point(int x, int y)
Constructs and initializes a point at the specified (x,y)
location in the coordinate space.
 Parameters:

x
 the X coordinate of the newly constructedPoint

y
 the Y coordinate of the newly constructedPoint
 Since:
 1.0
Method Detail
getX
public double getX()
Returns the X coordinate of this Point2D
in double
precision.
getY
public double getY()
Returns the Y coordinate of this Point2D
in double
precision.
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
 Since:
 1.1
 See Also:

Component.getLocation()
,setLocation(java.awt.Point)
,setLocation(int, int)
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  Since:
 1.1
 See Also:

Component.setLocation(java.awt.Point)
,getLocation()
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  Since:
 1.1
 See Also:

Component.setLocation(int, int)
,getLocation()
,move(int, int)
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
.
 Specified by:

setLocation
in classPoint2D
 Parameters:

x
 the X coordinate of the new location 
y
 the Y coordinate of the new location  See Also:
getLocation()
move
public void move(int x, int y)
Moves this point to the specified location in the (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  See Also:
Component.setLocation(int, int)
translate
public 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)
.
 Parameters:

dx
 the distance to move this point along the X axis 
dy
 the distance to move this point along the Y axis
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 classPoint2D
 Parameters:

obj
 an object to be compared with thisPoint2D
 Returns:

true
if the object to be compared is an instance ofPoint2D
and has the same values;false
otherwise.  See Also:

Object.hashCode()
,HashMap
toString
public String toString()
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
.
