In object-oriented programming, polymorphism is a concept where a function behaves differently, depending on the type of object that calls it. To understand the concept of polymorphism, we will continue with the Shape class example. Every shape has its own type and dimensions, but all shapes can be drawn on the screen. When the Circle class calls the draw function, it calculates the area and draws it. Similarly, if the Triangle class calls the draw function, it calculates the base and height and draws it. The same applies to the other classes. The idea behind polymorphism is that the draw function can display different shapes and the program can determine which shape of the function to call at the time of execution. There are different types of polymorphism used in Kotlin. In this section, we are discussing inheritance-based polymorphism. The idea behind this is that...

Overview of this book
Kotlin is an object-oriented programming language. The book is based on the latest version of Kotlin. The book provides you with a thorough understanding of programming concepts, object-oriented programming techniques, and design patterns. It includes numerous examples, explanation of concepts and keynotes. Where possible, examples and programming exercises are included.
The main purpose of the book is to provide a comprehensive coverage of Kotlin features such as classes, data classes, and inheritance. It also provides a good understanding of design pattern and how Kotlin syntax works with object-oriented techniques. You will also gain familiarity with syntax in this book by writing labeled for loop and when as an expression. An introduction to the advanced concepts such as sealed classes and package level functions and coroutines is provided and we will also learn how these concepts can make the software development easy. Supported libraries for serialization, regular expression and testing are also covered in this book. By the end of the book, you would have learnt building robust and maintainable software with object oriented design patterns in Kotlin.
