Kotlin is a static typed general-purpose programming language that focuses on multi-platforms. The language is developed by the JetBrains company, and the Kotlin trademark is held by the Kotlin Foundation.
Kotlin – similarities to other programming languages
Kotlin, in terms of its ideas and goals, is very similar to Apple Swift language used to create applications for macOS and iOS. Above all, the similarities between the two languages will help developers transfer applications from iOS to Android while maintaining the code’s essential performance and sense.
Combining this fact with the restrictive policy of using Java free of charge has made the Android community much more likely to choose Kotlin to develop applications.
Kotlin and Java
Kotlin is designed to work with Java. Therefore, it is possible to combine these two languages in one project-based on JVM. Kotlin introduces many improvements and is a much more precise language than Java, but it may be a bit more complicated than Java. The code written in Kotlin is more concise, but at the same time, it better communicates the intentions of the programmer, who, with the help of convenient mechanisms, must declare what he/she wants to do. The language also has constructions that help to avoid logical mistakes and improve the readability of the code. Also, null safety is built into the Kotlin, so there will be less severe problems with NullPointerException and a few other conveniences, which will undoubtedly be missing in Java.
However, it is essential to remember that Java is still the most popular programming language. Most existing projects and libraries are written in Java, and it will take a long time to change that. Therefore, the best solution is to know Java before Kotlin. Changing the developer’s leading programming language is very smooth, relatively painless, and most importantly – the developer knows how the language works underneath, so solving problems is then much more effective.
