Explanation of Solution

setRotate method:

• The method “setRotate” rotates a node about its center.
• Any node present in scene graph can be rotated using the method.
• The parameter “ANGLE” is passed to it as an argument.
• It denotes rotation angle in degrees.

Example:

The example for “setRotate” method is given below:

Rectangle bx = new Rectangle(X, Y, W, H);

bx.setRotate(ANGLE);

Here, “bx” denotes an object of “Rectangle” class. The values “X” and “Y” denotes coordinates of rectangle and “W” and “H” denotes width as well as height of rectangle respectively...
