The following article describes the Features of Kotlin that make it different from Java.

As can be seen, Kotlin has gained popularity among developers due to its modern language features and a high level of interoperability with Java. The following list shows some of the key features of Kotlin that make it popular.

Features of Kotlin to Make it Popular

  1. Null Safety. Since Kotlin has a built-in null safety feature, so it helps prevent null pointer exceptions, which are a common source of bugs in Java.
  2. Conciseness. Also, Kotlin is often considered more concise than Java. Because it requires lesser code to do the same tasks. Because, it supports functional programming constructs like lambdas, the programs are shorter. Actually, these constructs greatly simplify code.
  3. Interoperability. In fact, Kotlin and Java are interoperable. So, Kotlin and Java code can work together. In other words, Kotlin code can call Java functions. Also, the reverse is true. Moreover, it can integrate with Java libraries.
  4. Extension Functions. With Kotlin you can define extension functions, which are functions that can be called on an object as if they were part of the object’s own class. Therefore the code becomes more readable and expressive.
  5. Immutability. Also, Kotlin provides built-in support for immutability. Hence, it makes code safer and easier to reason about.
  6. Coroutines. Furthermore, Kotlin provides built-in support for coroutines. So, you can write asynchronous code that is easier to read and maintain than traditional callbacks or threads.
  7. Data Classes. Also, Kotlin provides built-in support for data classes. Actually, these are classes that specifically hold data but have some built-in functionality. For instance, these classes support features like equality and copy methods.

To summarize, Kotlin offers a modern and streamlined approach to programming. Moreover, it addresses many of the pain points of Java. While it maintains full interoperability with Java and the Java ecosystem.
