But for now, to make the long story short, I’d like to say this – anyone working with Android must have a working knowledge of Java, even if you wish to specialize in Kotlin or any other language later. In the later part of this article, I will discuss the pros and cons of each language in detail, so you can decide for yourself which language you want to learn. So which language should you choose to learn? Jesica Thornsby of Tutsplus has some food for thought on the Kotlin vs. So definitely, Java has its place too, that is hard to compete with. What about the fact that Java has been around for about 20 years now, is the language Android itself is built on and has been hugely revered among Android developers for a really long time now? Unavailable, has declaration-site variance and type projects as an alternative Although, can have multiple constructors (constructor overloading)Ĭan have one or more secondary constructors Variables of a primitive type are objectsĬan’t have secondary constructors. Variables of a primitive type aren’t objects Lambdas expressions are introduced in the Java 8 Higher-order functions are implemented using Callables. Requires adding only the data keyword in the class definition Required to write a lot of boilerplate code But does that automatically make it the first choice for Android development? Feature It is robust, statically typed and much less verbose than Java.

Kotlin is a programming language that can be used for any kind of development – server-side, client-side or web. It’s developed by JetBrains. It is fully compatible and interoperable with Java. To quote the official documentation, Kotlin is an open-source statically typed programming language that targets the JVM, Android, JavaScript and Native. Kotlin filled that gap, and has been loved by developers ever since it was announced as the official language for Android. Despite the undisputable reputation of Java as a programming language, Android was long in need for a modern language.
