Explanation of Solution

setScaleX method:

• The “setScaleX” method scales a node in its X dimension.
• It can be used to scale any node in scene graph.
• A “double” argument is passed to the method that denotes scaling factor.
• To retain node into original manner, both X and Y dimensions should be scaled same.
• If different values are used for X and Y dimensions then node will seem stretched.

Example:

The example for “setScaleX” method is given below:

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

bx.setScaleX(0.5);

Here, “bx” denotes an object of “Rectangle” class...
