Answer 2

have a look at this code: its a simple example of how to describe in code a real life scenario using OOP. Have a look att the constructor function (like a jar class).
From the constructor are instantiate the small and the big jar. everything happens in the draw function and on touch events. https://code.sololearn.com/W6WmRd8cd5KT/?ref=app
