Round Rectangles in Java Swing Example

The RoundRectangle2D class lets you draw a rectangle with corners rounded. The construction of the box is identical to that made ​​with the class Rectangle2D, the only difference in this case are two additional parameters to end of the constructor, which indicate the width and length of the curve defining each corner. The larger these values ​​will have higher level of rounding the corners.
