Method Details- 
getXpublic double getX()Returns the X coordinate of the upper-left corner of the framing rectangle indoubleprecision.- Specified by:
- getXin class- RectangularShape
- Returns:
- the X coordinate of the upper-left corner of the framing rectangle.
- Since:
- 1.2
 
- 
getYpublic double getY()Returns the Y coordinate of the upper-left corner of the framing rectangle indoubleprecision.- Specified by:
- getYin class- RectangularShape
- Returns:
- the Y coordinate of the upper-left corner of the framing rectangle.
- Since:
- 1.2
 
- 
getWidthpublic double getWidth()Returns the width of the framing rectangle indoubleprecision.- Specified by:
- getWidthin class- RectangularShape
- Returns:
- the width of the framing rectangle.
- Since:
- 1.2
 
- 
getHeightpublic double getHeight()Returns the height of the framing rectangle indoubleprecision.- Specified by:
- getHeightin class- RectangularShape
- Returns:
- the height of the framing rectangle.
- Since:
- 1.2
 
- 
isEmptypublic boolean isEmpty()Determines whether theRectangularShapeis empty. When theRectangularShapeis empty, it encloses no area.- Specified by:
- isEmptyin class- RectangularShape
- Returns:
- trueif the- RectangularShapeis empty;- falseotherwise.
- Since:
- 1.2
 
- 
setFramepublic void setFrame(double x, double y, double w, double h) Sets the location and size of the framing rectangle of thisShapeto the specified rectangular values.- Specified by:
- setFramein class- RectangularShape
- Parameters:
- x- the X coordinate of the upper-left corner of the specified rectangular shape
- y- the Y coordinate of the upper-left corner of the specified rectangular shape
- w- the width of the specified rectangular shape
- h- the height of the specified rectangular shape
- Since:
- 1.2

getBounds2DReturns a high precision and more accurate bounding box of theShapethan thegetBoundsmethod. Note that there is no guarantee that the returnedRectangle2Dis the smallest bounding box that encloses theShape, only that theShapelies entirely within the indicatedRectangle2D. The bounding box returned by this method is usually tighter than that returned by thegetBoundsmethod and never fails due to overflow problems since the return value can be an instance of theRectangle2Dthat uses double precision values to store the dimensions.Note that the definition of insideness can lead to situations where points on the defining outline of the shapemay not be considered contained in the returnedboundsobject, but only in cases where those points are also not considered contained in the originalshape.If a pointis inside theshapeaccording to thecontains(point)method, then it must be inside the returnedRectangle2Dbounds object according to thecontains(point)method of thebounds. Specifically:shape.contains(p)requiresbounds.contains(p)If a pointis not inside theshape, then it might still be contained in theboundsobject:bounds.contains(p)does not implyshape.contains(p)- Specified by:
- getBounds2Din interface- Shape
- Returns:
- an instance of Rectangle2Dthat is a high-precision bounding box of theShape.
