Why Should You Prefer Kotlin for App Development?

Thousands of Android applications are powered by strong programming languages like Java, which has been the de facto face for web development for the past two decades. The newest entrant in the world of JVM (Java Virtual Machine) software programming languages is Kotlin. And soon after its initiation, Kotlin has garnered the attention of Android developers because of faster and safer performance of writing Android applications. Productivity is highly boosted by this language.

Kotlin language is Android-friendly. It is as an open-source language which has the compatibility for cross-platforms working. This general-purpose, modern, statically typed programming language is ideal for mobile application development on Android. It enjoys the official nod from Google as one of the most preferred JVM languages for the development of mobile applications on Android. So, what makes Kotlin count on its ever-increasing popularity? The reasons are -

  • Kotlin Language Is Modern and Expressive

    As a language, Kotlin is hassle-free because it involves lesser writing of boilerplate code. Fewer codes have a couple of advantages – time to test and maintain is reduced. Hence, developers can focus more on innovative ideas of Android applications.

  • Safe Coding Feature

    The app quality can be enhanced by avoiding NullPointerExceptions with @Nullable and @NonNull type features of Kotlin. This language helps to minimize commonly occurring programming mistakes.

  • Interoperability with Java

    Kotlin gels well with Java. Kotlin codes can be called from a Java-based program and vice-versa. The best of both can be achieved by co-working with the codes of Java and Kotlin. Hence, developers who have knowledge in both are highly appreciated, just like the app development experts at Flatworld Solutions.

  • Highly Scalable

    Building up highly scalable server-end applications with ease gives Kotlin language the edge. Such applications we build can easily handle a large number of clients with a slight upgrade in hardware.

  • Tool-friendly Language

    Java IDE can be chosen and application program can be built up from the command line. Kotlin also supports tooling specific to frameworks like Spring, Vert.x, Ktor, and Kotlinx.Html.

  • Less Redundancy, Fewer Errors

    Developers working on the Java platform will agree that writing a program with Java codes require a lot of coding for the simplest of task or action. But Kotlin solves this problem because code redundancy is reduced. Concise codes take less time to write, read and are least likely to be affected by bugs. Kotlin calls for seamless integration of Java APIs (Application Programming Interfaces). Kotlin minimizes the complicated and complex processes involved with Java codes.

  • Migration feature

    Kotlin programing language allows migration of large Java codebases to Kotlin in a simple, step-by-step manner. Developers can start writing newer codes with Kotlin while keeping intact the older codes of the system in Java language.

  • Easy to learn

    Just as migration is easy, learning Kotlin with complete knowledge in Java is easier. Moreover, the presence of automated convertor, included in the Kotlin plugin, helps to change Java codes to Kotlin in the initial phases of learning.

  • Great Alternative to Java

    Kotlin is ideal for server-side developmental purposes. The inherent features make the language easy-to-use for developers. It is indeed a good alternative for Java fit for Android, browsers, JVM and native solutions.

    Down the years there have been many programming languages eying the top spot among JVM supported programming languages like Java, Groovy and Scala. But Kotlin is the best of the lot among JVM languages and is here to stay.
