What’s Kotlin? Why Should You Be Learning Kotlin?

With time, new and new technologies are being put on the display. These tech gears and equipment use their own algorithms and programming languages. To carry out the desired tasks by the programmers, by the stakeholders, and by the masses. Programming has never been such a vast field as it is now. New and different types of programmers are available, that work in their own fields. Such is the language Kotlin.

Kotlin Overview:

For the start, Kotlin is a Java-based language. Which can be seen by the fact, that it runs on the Java Virtual Machine. What it does for us is it lets our applications run on every Operating System (Which is also an advantage of Java). The advantage is, that every application we are going to code, is easily portable to every Operating System.
Another fact is, you can use the Kotlin, for coding Android Applications. Which means Java can work really well alongside the Kotlin. Which makes them both interoperable and specifically it can also be used write the web applications. It is an Object-Oriented Language same as the Java.

Why Should you be learning Kotlin:

“Why should you be learning the Kotlin?” is the question that might pop in your brain. You are right to think that. Kotlin has been recently released in its version 1 beta. Developed by the company named JetBrains which also creates IDE IntelliJ. The purpose of telling you this is to let you know that there are great tools to learn Kotlin also a big company is behind it development. Ensuring this language won’t fade away with time or lose its worth.
The major advantage of using Kotlin is you can use whole Java Library right inside your Kotlin code. Also, you can integrate Kotlin code into any existing Java projects you may have. In fact, the JetBrains even has a converter that converts your Java files to equivalent Kotlin files and also the other way around.
That is not just there, Kotlin also improves on some of the more annoying sides of Java. So first of all its more concise. In Java sometimes you have to write lots of code not really contributing to your application but just clutters your code. For example, you might have some classes which basically just hold some data and you have to define getters and setters, you have to define equal – code – string. Which is really just boilerplate code.
Another advantage of Kotlin is, it makes the code much safer. Most importantly it does a really good job at avoiding the null pointer exceptions completely, which if you have been programming Java before is a really big deal. Because that’s the most frequently occurring type of exception.
The most important advantage of Kotlin vs Java is the feature set. Kotlin inducts some important new capabilities for Android Development projects that you can’t or won’t find in Java.

Language for 2018:

People have been rating Kotlin very high, and since its available for Android Development now, you can get very good jobs in the software world learning Kotlin. Kotlin has been compared to the Java same as Swift has been compared to Objective C. Like Swift, Kotlin is simple, clean and removes a lot of codes bloat from Java. Kotlin also adds some needed features that Java doesn’t yet support in Android. The Learning Curve for using Kotlin is very low. Any experienced Java Developer can pick up Kotlin in a few hours.
You can also use Kotlin in Java files, and you will see them working together really fine.


Some among my favorite features of the Kotlin include are mentioned as follows:
  1.       Nully safety through nullable and non-nullable types, safe calls, and safe casts.
  2.       Extension Functions
  3.       Higher-order functions / lambda expressions.
  4.      ·Data Classes.
  5.      ·Immutability
  6.           Coroutines
  7.          Type aliases


While Kotlin improves in many ways over Java, developing with Kotlin for Android presents some challenges, though every new release is helping. An app built with Kotlin will likely result in a larger file package size than one built purely in Java. That is why Kotlin has its own library that’s added on top of Java’s standard library. Also, the build time for Kotlin is a little slower.
