Kotlin programming language is the preferred language for android developer, since 07 May 2019, Google announced Kotlin programming language. Even though, there are many developer still using java. Many developer still they are not convinced about kotlin.
Lets discuss about pros and cons of kotlin and java in this article.

Java has been the only language for building Android apps for years. The Internet is flooded with resources to learn and execute Java codes and come up with innovative Android applications. However, it is not a modern language. In addition to this, the developers have to face various issues while performing coding using Java language. According to our Android app developers, various Java updates continued to hit the market, but none could satisfy the need of developers for creating something ‘out of the box’. Even with a workaround, back-ports, and tools to mitigate the associated hurdles, there are limitations with Java language as a whole that created issues with Android API design along with annoying risks and errors. Hence, there was a need for improvements.

Here some reason for why Kotlin is best for android development.



Advantages of using Kotlin over Java

Simplicity

Interchangeability

Easier to Maintain

Fewer Issues

Object-oriented as well as functional

Offers null-safety

Tailor-made to boost productivity

Data Serialization

Extension functions

Co-Routines



Co-Routines

Java async execution on Android is not fun to do. You have to juggle managing the UI thread and a network call at the same time. There are two main ways to do this:

Callbacks: These aren’t pretty, and they don’t allow a request to be canceled.

rxJava: If you can get over the steep learning curve, rxJava does enable a request to be canceled but it has no callbacks.


Kotlin’s co-routines help us write async code in a blocking fashion. This way we can just focus on the data rather than how to fetch it. Co-routines are lightweight threads. They don’t block the execution of the thread they work in, but they can suspend their own execution.

Seeing these features of Kotlin, it can be clearly said that the language has a bright future ahead. Opting for the language can enable you to get a better Android app within a shorter span of time.



Disadvantages of using Kotlin over Java

Using Kotlin means you have another dependency to take care of. By that we mean, there are at least three things to keep in sync, Kotlin language version, Kotlin plugin version for Android studio and Kotlin Gradle plugin version.

Kotlin introduces some cool ideas, like co-routines. But these are experimental and as a result, you may experience an occasional bug.
As you can see, there are significant reasons to use Kotlin. You’ll need to get set up to integrate Kotlin, but I think it’s worth the time commitment.
