What is Kotlin used for? Why Do Developers Choose Kotlin
Kotlin is an Object-Oriented, Functional-style programming language for the JVM, Android, and the browser. It is 100% interoperable with Java, which means you can use Kotlin together with Java in the same project. Kotlin is pragmatic: it has obvious, intuitive syntax, which allows you to be productive with it in a very short time. Kotlin is focused on interoperability with Java and other JVM languages. It’s designed to work in harmony with all of them, meaning you can use it together with Scala, Clojure, Groovy, etc. on the same project.
Kotlin is used by Google for Android app development. It is also used by the web development company on an array of interesting platforms like Android, JavaScript, Native, etc.
What are the Advantages of Kotlin?
Kotlin’s creation came after principal developer Dmitry Jemerov looked for features that could not be found in Java. Scala, another language that runs in Java Virtual Machine (JVM), was close to what I wanted, but it took too long to compile it.
Jemerov wanted a language that would have all the features of the most modern programming languages, that would run in the JVM and compile as fast as Java. Then he created his own language, Kotlin.
You can reuse Java on the Android operating system. In late 2019, Google made the final decision for Jemerov and the mayor of Android developers and named Kotlin the era of the preferred language for developing Android applications.

Reasons Why Developers Choose Kotlin Over Java
1. Shorter program for the same task Kotlin is a statically typed language that is very easy to read and write. It has much simpler and shorter code than Java code for the same problem. As this makes the language more human readable, it becomes easy to debug. Kotlin’s code is much smaller and speeds up the programming process compared to Java. This is due in part to Kotlin’s nifty IDE.
2. Simple code Kotlin programs do not need semicolons in their program. This makes the programs easy to read and understand. They also have smart castings and chain models. Java is not a terse language. Such a language code increases the probability of errors. Code in a concise language means less risk of runtime and compiler errors. Kotlin provides an easy way to use mutable and immutable declarations for various data structures.
3. Java Compatibility Kotlin can easily share and use information from Java in different ways. Java and Kotlin code can coexist in the same project. Additionally, various Java libraries can be used in Kotlin projects, making them even more compatible. Not only Java libraries, but also many Java frameworks are supported by Kotlin, including some advanced frameworks. You can use Kotlin from Java without major steps like converting an entire project to Kotlin. This is a huge advantage for developers because they don’t really have to drastically learn a new language. Anyone familiar with Java will know and be able to program in Kotlin. Translating Java to Kotlin is easy. In IntelliJ or Android Studio, the only thing needed as a Kotlin plugin is to translate Java to Kotlin.
4. Null Reference Removal: One of Kotlin’s biggest advantages over Java is null references. Sir Tony Hoare, a British computer scientist, calls this reference zero the trillion-dollar error. Accessing a member of a null reference results in a null reference exception. This is one of the main drawbacks of Java, known as NullPointerException or NPE. Kotlin’s type system is intended to remove NullPointerException from code. The only possible cause of NPE can be An explicit call to throw NullPointerException(); By using the !! the operator described below; Some data inconsistencies related to initialization, e.g. B if An uninitialized this, available in a constructor, is passed in and used somewhere (“filtering this”); A superclass constructor invokes an open member whose implementation in the derived class uses an uninitialized state; java-interaction: Generic types used for false-null Java interop, e.g. a piece of Java code can insert a null value into a Kotlin MutableList, which means that MutableList must be used to work; Other problems are caused by external Java code.
5. Fixed some Java vulnerabilities Plain-old Java has a number of flaws. Inhibits the well-known problem of a null pointer. Kotlin attempted to overcome these obstacles created by Java. He borrowed things from various languages like C# and mainly Scala to overcome the difficulties of Java. It contains instances of the Pascal language and is considered highly influential in the development of Kotlin. Things like parameter lists and variable declarations with the data type after a variable can also exist in Kotlin. Kotlin eliminates boilerplate code and greatly eliminates potential bugs. This would normally result in a runtime explosion as the compiler doesn’t recognize it.
What is Kotlin used for?
Kotlin is a general-purpose programming language that runs on the Java Virtual Machine and also can be compiled to JavaScript source code or uses the LLVM compiler infrastructure. Kotlin is a language that was developed to be an industrial strength object-oriented programming language with the help of the team leader Andrey Breslav, who is a well-known developer. Kotlin is fully interoperable with existing Java code and has been designed with a strong emphasis on interoperation with all Java frameworks. Kotlin can be used as a Java library in a mixed project.
Kotlin was developed to make writing code easier, safer, and more fun.

Why Kotlin is the Future of Android Development:
Kotlin is the new hot programming language in the Android development world. The main reason why it has gained so much popularity is that it is interoperable with Java and has been developed by JetBrains, the same people who have developed IntelliJ IDEA. This is a very important thing for developers. If you have used Android Studio, then you must have noticed that it is the same editor that JetBrains has developed for IntelliJ IDEA. Kotlin has made Android development tasks a lot easier.
If you are familiar with java and want to try out a new programming language then Kotlin is the best option. The syntax is quite simple and easy to understand. There are many new benefits of Kotlin over java. Not only is it easy to read and write, but it is also safer, it has null safety and type safety built into the language. Kotlin is also a very powerful tool for Android development. It has wonderful extensions to make android development a lot easier.
Android apps are getting bigger and bigger and more complex with every passing day. When I started with Android development, you could build a simple app with a few buttons and text fields. That was quite some time back. As the apps became more complex and had more features, the code base started getting bigger. And bigger. And bigger.
Now, it’s almost out of control. You see a lot of apps that have millions of lines of code. And it’s not just the number of lines of code but also the number of classes and packages. In large apps, you get the feeling that you’re lost, that you don’t know where you are or what you’re looking for. You also have the problem of multiple developers working on the same project, which means multiple sets of coding standards, multiple libraries, and multiple bugs. You could try and limit the number of packages and classes, but that’s not a long-term solution.
Conclusion:
Kotlin is a statically-typed programming language for general-purpose programming. It was developed by JetBrains from Russia. Kotlin is officially supported as a primary language for Android development. It is 100% interoperable with Java and can also be compiled to JavaScript source code or uses the LLVM compiler infrastructure.
