      Specified by:
        `getX` in class `Point2D`

        1.2

    - #### getY

          public double getY()

      Returns the Y coordinate of this `Point2D` in `double` precision.
      Specified by:
        `getY` in class `Point2D`
      Returns:

      Since:
        1.2

    - #### 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

                                  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:

    - #### 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 class `Point2D`
      Parameters:
        `x` - the X coordinate of the new location

    - #### 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 class `Point2D`
      Parameters:
        `obj` - an object to be compared with this `Point2D`
      Returns:
        `true` if the object to be compared is an instance of `Point2D` 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`.
      Overrides:
        `toString` in class `Object`
      Returns:
        a string representation of this point
