Kotlin, which is Android’s new official programming language, is the quickest developing programming language. Such is the ubiquity of this programming language that Google as of late made Kotlin an official programming language for Android.
While Java is still most generally utilized, it is an old and blunders inclined programming language. Kotlin is currently rising as a commendable elective for Android application advancement.
What’s wrong with Java?
1. Old Programming Language
Some may accept that Java being an old Android app development programming language it would be increasingly reliable, yet the inverse is valid. Java on Android doesn’t support lambdas, method references, streams.
Despite everything, you need to utilize Java. Time APIs to compose applications. There are third-party tools like Retro Lambda; Streams backport that you can consider yet it is as, however, an issue.
2. Inclined to errors
The most significant blemish in Java is how it handles the ‘null’ exception. The error-prone nature of Java is the most common reason why Android applications crash.
Today it is practically difficult to have a production application that doesn’t have a solitary NullPointerException. Java makes it progressively hard for designers to deal with null exceptions.
Engineers with access to modern tools favour composing perfect and brief code. Less code sets aside less effort to formulate, read, and execute.
With Java, you have to arrange enormous pieces of code to complete the necessary things. Java with Android forces developers to experience several strides to perform simple tasks like getting to a database or dealing with fragment translations.
Why is Kotlin Better?
1. Interoperability with Java
The principal thing you would adore about Kotlin is that it is 100% interoperable with Java. You can flawlessly call Java code from Kotlin and the other way around.
Utilizing Kotlin in your current Android app development venture is particularly conceivable. You can begin using Kotlin for little pieces of your project, while the rest of the venture can, in any case, be in Java. The blend of Java and Kotlin code functions admirably in Android ventures.
2. IDE and tooling support
You don’t need to stress over proceeding with help while utilizing Kotlin. All the Android Studio’s IDE highlights work flawlessly in Kotlin.
You should introduce the Kotlin module in Android Studio to make it work. There is a module to change over Java documents to Kotlin also.
3. Moderate code
If you change to Kotlin, one of the main things that you will notice is the measure of code that you compose. The fewer lines of code lessen the document sizes for Kotlin when contrasted with Java reciprocals.
Indeed, even the code is increasingly coherent and easy to understand when compared with Kotlin. When you comprehend the Syntax, reading Kotlin code turns out to be very simple.
Kotlin vs Java – Which is Better for App Development
1. Countering NullPointerExceptions
Android App Development Companies coding with Java has continually been managing the NullPointerExceptions. If a null value is relegated to any of the object references, this particular case is tossed. Be that as it may, Kotlin avoids this issue – all gratitude to its natural null safety feature.
Unless specially marked as “nullable,” no factor in the Kotlin code can hold an invalid worth. Along these lines, regardless of whether you do misallocate a null value, the code will fail through the compilation procedure.

2. Interoperability – An Added Advantage
Java and Kotlin work flawlessly in tandem, sans danger of any error within the same project. This interoperability is a help for the coders as both Java and Kotlin classes can live simultaneously in the venture.
This gets rid of the requirement for full venture transformation (to Kotlin) or starting a project from scratch. This permits Kotlin libraries to be utilized in Java ventures while maintaining the legacy Java codes unblemished.
3. Higher-Order Functions and Data Classes
The entry of Java 8 has made life simpler for Android app development company developers as support was at last reached out for lambdas.
However, there are still impediments with regards to features. Kotlin, then again is much more developer-friendly as it enables variables to have the option to store functions for later use.
4. Checked Exceptions – Not any longer!
Checked exceptional cases are synonymous with Java, as Android application developers are known to ‘catch and declare’ the exceptions, while it is not a prerogative with regards to Kotlin application development.
Java 8 (being predominantly procedural) brags of features like type annotations, lambda articulations, and strategy references on Android. Kotlin’s development brings the best of procedural and functional programming for developers.
Kotlin to put it plainly, is unassumingly an upgrade on Java, as opposed to a substitute. If you are a specialist Android application developer with tremendous experience in Java, taking a shot at Kotlin will be a cakewalk. It is an increasingly dynamic, lightweight, and knowledgeable language.
