What is Kotlin: Its Features & Benefits

Kotlin Training

Kotlin is a modern programming language designed for JVM (Java Virtual Machine) and Android. In addition, it combines object-oriented and functional programming features and is totally focused on interoperability, safety, clarity, and tooling support. This language has a cleaner and more compact syntax as it does not require semicolons and allows return type for Unit functions. Furthermore, it is open source and provides a single-click tool using which, developers can convert existing Java code. This programming language supports full Java interoperability which attracts many Java developers as well as Android app developers.

Features of Kotlin

Kotlin allows developers to switch the programming language instead of changing the codes. Furthermore, it comes with lazy loading features that increase startup time and are very useful for Android development. These features allow developers to load only resources into the main memory which is necessary. Kotlin allows developers to write the equivalent of the same Java code in a simple manner, and with lesser code. Moreover, this language facilitates collection filtering and makes it easier to tell what your resulting list should contain. To further know about it, one can visit Kotlin Training in Gurgaon. Apart from these, given below are some of the features of Kotlin.

• Extension Functions- It has a very useful extension that allows developers to add methods to classes without changing source code. This language allows you to add methods on a per-user basis to classes.

• Reduces Crashes at Runtime- This is the most advanced feature, where it is easy to identify the Null Pointer Exception while compiling your Android app development project.

• Smart Cast Function- This feature results in effectively reduces the application’s speed and focuses on improving the performance of the app. Furthermore, it helps in performing all operations that are coded for a specific type.

• Low Cost- It provides a no or low cost of adoption that is associated with it its usage. Furthermore, it is open-source, so you do not have to spend over Kotlin for its license.

• Standard Library Functions- Kotlin offers standard library functions that help developers easily work on an Android mobile app development project. Moreover, it provides multiple utilities to work with char and string sequences.

Benefits of Using Kotlin

Kotlin is fully interoperable with Java and it allows you to freely call Java code and Java interfaces. In addition, it permits you to use Java frameworks, libraries, etc. Implementing it in an existing Java project doesn’t require any rework on any existing code. This language is simple and understandable and even developers that have never studied Kotlin can easily conduct a code review. An experienced developer can easily learn the syntax of this language takes several hours. Furthermore, this language provides Backend support and comes with ktor, http4k, and other native frameworks for backend developers. Kotlin ensures compatibility with all Android versions while other languages have some restrictions. Many institutes provide Kotlin Training in Delhi and one can enroll in them to start a career in it. Apart from these, given below are some of the benefits of using Kotlin.

• Kotlin allows writing less code- Kotlin facilitates less code writing and ensures high readability. Less code results in fewer bugs and allows you to focus on more important things. This language facilitates readability, simplicity, and the app development process.

• Solves developer challenges- It is a simple and effective tool that can be used together with Java and work everywhere. Thus, it solves challenges faced by programmers and helps you avoid null pointer exceptions.

• Easy to Adopt- This is an easy-to-adopt language that allows you to facilitate product maintenance or streamline custom Android app development. All you need to do is assign two or three engineers to move the project to Kotlin.

• Fully compatible with Java- This programming language is fully compatible with Java and it provides developers access to Java frameworks and libraries. Thus, permitting engineers to use both languages when building a mobile product.


Kotlin is a modern programming language useful for JVM (Java Virtual Machine) and Android. It combines object-oriented and functional programming features and has a cleaner and more compact syntax. It offers various features like extension functions, smart cast functions, library functions, and many more. Furthermore, it allows developers to switch the programming language instead of changing the codes. In conclusion, Kotlin ensures full compatibility with Java and provides developers with easy access to Java Frameworks and libraries.
