With its growing popularity as a functional and pragmatic programming language, many programmers are looking to explore its potential. Some refer to it as the 'Java alternative' (it is completely Java interoperable). Kotlin is a modern, statically typed, cross-platform programming language with type inference. To do this, we call the interface's draw() function, rather than asking the object 'What shape are you?', before trying to call the appropriate drawTriangle(), drawRectangle(), drawCircle(), or any of the other implementations. The strengths of polymorphism come to play when whoever is using the object doesn't really care about the final shape or rendering of said object - We just want the damn drawing to render its final shape. When I first learned object-oriented programming, the classical image of polymorphism portrayed the interface of a drawable object (a shape), where the various implementations would render e.g.In real life, one may think of a man implementing various behaviours as a father, a husband, a co-worker etc.

Polymorphism is the provision of a single interface to entities of various types, which means applying multiple meanings or behaviours (implementations) to a single object type depending on the context.
