Introduction to Kotlin: a powerful programming language

Kotlin is a statically typed, cross-platform, general-purpose coding language that features type inference. It can interoperate with JVM and Java based on the Java class library. However, type inference also has a concise syntax. Let’s find out more about this programming language.

Basically, the main purpose of Kotlin is JVM, but it can also be compiled into JavaScript or native. JetBrains is responsible for language development costs. On the other hand, the Kotlin Foundation offers protection for the Kotlin brand.

Officially, Kotlin is supported by Google for mobile development on the mobile operating system giant Android. After the introduction of Android Studio 3.0 in 2017, the language has become a good alternative to the normal Java compiler. With this compiler, you can opt for Java 8 or Java 6 compatible bytecode.

Story

In 2011, JetBrains introduced Project Kotlin, which is a new encoding language for the popular JVM. According to Dmitry Jemerov, most of the languages ​​did not have the desired characteristics, except for Scala.

Also, he said that Scala has a flaw: it has a slow compile time. The goal of Kotlin is to allow faster compilation like Java. In 2012, the project was branded open source by JetBrains under the license called Apache 2.

JetBrains is hopeful that the language can drive IntelliJ IDEA sales. Kotlin v1.0 was released on February 15th. It is the first known stable release and also features backward compatibility.

During the 2017 Google I / O festival, the search engine giant introduced Kotlin support for Android. In 2017, Kotlin v1.2 came out. The next version came out on October 29, 2018 and brought coroutines for asynchronous encoding.

In 2019, the search engine giant Google announced that Kotlin is their preferred language for Android app developers.

Design

According to Andrey Breslav, Kotlin is a great object-oriented language, which has industrial strength. In addition, it is better than Java and can be interoperated with Java code, allowing many companies to gradually migrate to Java.

The semicolon is not required to end a statement. Usually a new line is enough to finish the declaration. Parameter lists and variable declarations allow you to put the data type after the variable name just like TypeScript and Pascal.

Variables can be immutable, mutable, or declared with the var or val keyword. By default, class members are open to the public and are also final. It means that you cannot create a derived class.

Apart from object-based programming classes and methods, this language supports the coding of procedures with functions. Kotlin functions offer support for overloads, named arguments, variable-length argument lists, and so on.

The functions of the members of the class are distributed based on the runtime type of the object on which they are called.

In short, if you are interested in the Kotlin programming language, we hope this article has provided you with a lot of useful information about the language. For more information, we suggest that you contact a good professional. I hope this helps.
