Developers around the globe are as yet thinking if Kotlin has any future or not. Be that as it may, with the presentation of Kotlin in Google I/O two years back, Kotlin has made its own place in the Android application development market.
To understand the comparison between Kotlin vs Java, first of all, we have to understand a little more about both the languages. We will begin with Kotlin and then for Java too.
What is Kotlin?
Kotlin arrived as an open-source and statically-typed programming language, in light of JVM (Java Virtual Machine) and made by JetBrains. Kotlin gave a modern touch to the area of Android Development and quickly filled in the weak zones that were prominent in Java.
The best part of Kotlin is that it enables developers to compose code that is interoperable with Java and can be arranged to utilize the JavaScript source code.
What is Java?
Java is a programming language made by James Gosling. In this, we can make any sort of program; it additionally supports any kind of machine. It is in Linux OS, Windows and furthermore for mobile in Android.
Right now, Java has one of the most significant and biggest communities in the world. This language, both on the Internet and in the computer field, is significant. Java can be utilized to do nearly anything.
It ought to be referenced that Java is totally free and can be utilized by anybody in the world. Along these lines, Java is a safe, amazing and a universal programming language.

Kotlin vs Java
1) Kotlin vs Java: Market
Kotlin for Android Development, although working in the background for quite a while, got a considerable amount of popularity in 2017, when Google declared that it would be the official programming language.
Soon, brands like Pinterest, Square, and so on moved their development tech stack to Kotlin.
In any case, the history that Java delivers in the Android application development world is verifiable. Furthermore, this history included with the way that Kotlin is still too new to even think about replacing Java as far as developer’s experience.
2) Kotlin vs Java: Null Safe
In Java, NullPointerException is a pain for the developers. It enables developers to assign null to any factor, nonetheless, while fetching an object reference that has a null value, it raises a null pointer exception which developers need to deal with.
On the other hand, Kotlin has attempted to fix this issue of Java by making all types of variable non-null able by default. That implies developers can’t assign null values to any variable/object. At the point when developers assign or return null values, Kotlin code will fizzle during order time. Be that as it may, we can declare a null value, as pursues:
“value num: Int? = null”

3) Kotlin vs Java: Extension Functions
Extension functions are not accessible in Java. To broaden the usefulness of existing class, developers need to take another class and acquire the parent class.
In Kotlin, developers can without much of a stretch broaden a current class with new usefulness. To broaden, a developer can create expand functions by prefixing the name of a class to name of the particular new function.
4) Kotlin vs Java: Performance
Since performance is one of the most significant viewpoints to think about when picking a programming language, we should initially figure out which one would make applications work better.
Kotlin’s byte code structure is practically indistinguishable from Java which makes applications run similarly as quick, along these lines, superficially, there is no reasonable leader in this class.
In any case, when we look closer, we see that Kotlin can support inline functions which empower the code that fuses lambdas to run quicker than the one composed by Java. Having said this, at last, the code composed by developers will decide how quick an application will run. This is just on the grounds that the byte code is so comparable.

5) Kotlin vs Java: Popularity
At the point when Google launched its first steady release in 2016, Kotlin market share grew to 4.28% by May 2017. That selection increment to 7.54% by September 2017.
A survey directed in 2018 demonstrates that 100,000 stack overflow clients found over 7.54% of respondents use Kotlin for Android development.
6) Kotlin vs Java: Handling Long Run Network I/O or CPU-intensive Tasks
Java lets multi-threading out of sight yet it’s unpredictable. A string including a long-running I/O or CPU-intensive tasks.
Though in the Kotlin, a developer can run various threads. It supports coroutines. These things nullify the execution at a specific level without blocking any thread.
Thus Kotlin has a guiding edge over Java regarding taking care of long-running system I/o or CPU-intensive tasks.

7) Kotlin vs Java: Development Cost
Kotlin was one of the most prominent and worthwhile aptitudes toward the finish of 2018. The normal pay of the Kotlin developers is around $140 per annum.
As the interest for the Android application development is growing, the requirement for the capable Kotlin developers is also upgrading. Henceforth, you should prepare yourself to plan for a more extended time and higher manpower.
In comparison, employing cost for the Java developers are moderate then Kotlin. Since there are sufficient developers you can deal with as indicated by your task necessities.
8) Kotlin vs Java: Functional programming
Java is limited to object-oriented programming whereas Kotlin combines both object-oriented and functional programming.
9) Kotlin vs Java: Inline Functions
Variables that are accessed to in the body of the function are known as closures. Utilizing a higher-order function can impose a few runtime penalties. Each function in Kotlin is an object and it catches a closure.
Unlike Kotlin, Java doesn’t offer help for inline functions. In any case, the Java compiler is fit for performing inlining utilizing the final method. This is so because that last method can’t be overridden by sub-classes. Likewise, call to a final method is resolved at compile time.
10) Kotlin vs Java: Type Inference
Kotlin takes type inference to another level. There is no compelling reason to indicate the variable as the compiler will figure its type on its own.
Whereas Java requires developers to specify the type of every variable explicitly during declaration.
kotlin vs java which is better
In view of our experience and the Kotlin vs Java analysis, we accept that Kotlin works impeccably & perfectly for startups and already settled organizations, and it remains proficient and reduces the number of boilerplate code. So let’s build your Android app with Kotlin.
