It's an open-source language that can also compile code to bytecode and run on Java Virtual Machine (JVM), enabling it to work on almost any platform. Kotlin is much younger than Java, since it was first introduced in 2016. In fact, Java's syntax shares some similarities with C and C++ but provides fewer lower-level facilities.
Moreover, Java is statically typed, performing type checking during compile time. In addition, since it is compiled to bytecode, it can run on any Java Virtual Machine (JVM). As a multiplatform language, Java works on almost any device, operating system, and server. It is an open-source, general-purpose, object-oriented programming language. Java was launched in 1995 and developed by James Gosling at Sun Microsystems (which in 2009 was acquired by Oracle).
Functional Programming: Higher-Order Functions and Lambdas Afterward, we'll discuss whether Kotlin is or not better than Java and highlight the main reasons. Facebook Linkedin Image of Kotlin logo versus Java logo.ĭo you prefer Kotlin or Java for Android development? This article seeks to explain the 12 main differences between both programming languages. This helps illustrate how to write well structured, clear, idiomatic Kotlin to build real applications.Shape Created with Sketch. These examples are supported by a public GitHub repository that provides complete working code as well as sample solutions to the chapter exercises. The book concludes with an introduction to Android mobile application development using Kotlin.Ĭlear steps are provided explaining how to set up your environment and get started writing your own Kotlin programs.Īn important aspect of the book is teaching by example and there are many examples presented throughout the chapters. The third part presents container data types such as Arrays, and collections including Lists, Sets and Maps and the fourth part considers concurrency and parallelism using Kotlin coroutines. The second part focusses on object oriented programming techniques, these include classes, inheritance, abstraction and interfaces. Subsequent chapters explain how functions are implemented in Kotlin and introduce concepts from functional programming such as higher order functions and curried functions. The first part of the book introduces Kotlin program structures as well as conditional flow of control features such as if and when expressions as well as iteration loops such as for, while and do-while. This textbook assumes very little knowledge of programming so whether you have dabbled with a little JavaScript, played with a bit of Python, written Java or have virtually no programming experience at all you will find that it is for you.
