These days, many developers prefer Kotlin over Java for Android development. One of the reasons for this is Google’s announcement in 2019. In that announcement, Google declared Kotlin as its preferred language for android app development and endorsed complete support for it. Another reason is based on the fact that Kotlin is more concise and also interoperable with Java. Now, Kotlin is being perceived as an alternative to Java.

Some of the other advantages of Kotlin include:
Kotlin can be said as an all-rounder language since it provides support to multiple kinds of development. Here is an insight into Kotlin’s all-round development capabilities.
Some of the major features of Kotlin are the following:
Both Kotlin and Java are powerful languages with rich features. Java, being one of the oldest object-oriented programming languages, has an excellent feature in the form of concurrence, which allows the execution of multiple statements. Besides, Java is an independent programming language, which provides – write once, run anywhere. On the other hand, Kotlin is a modern day’s language, which has advantages including conciseness, interoperability, less error-prone, and less learning curve, etc.
If we look at the differences between these two, Kotlin has a slight edge over Java having features such as null safety and lambda expressions whereas Java doesn’t support these. On the other hand, Java is better than Kotlin in terms of compilation speed and code development speed. Besides, the community circle of Java is bigger than Kotlin. Though Kotlin looks more concise and also more streamlined, when compared to Java, both have their advantages and disadvantages. What is needed to be understood here is - they cannot replace each other but they exist on their own. However, they can be used hand-in-hand in Android development.
Does it mean Scala is better than Kotlin? Or Kotlin has an edge over Scala? Or both are equally capable? Now, let us see the differences between Kotlin and Scala.
Here is a comparative insight.

|Most preferred language in the Android community||Doesn’t have much support from Android|
|Ranked 11th among the best programming languages to learn first||Ranked 17th among the best programming languages to learn first|
|Expressible, concise, and efficient code||Supports Macros, Pattern Matching, and Higher-Kindred Types|
|Provides functional and object-oriented paradigm features||Operator overloading|
|Succeed Java efficiently because the codes of Kotlin and Java are inter-convertible||Large community support|
|Looks similar to Java and endures object-oriented features|
|Works well Java programming tools including Maven, Eclipse, and Gradle, etc.|
|No support to pattern matching||Lacks speed in the compilation|
|Absence of raw types||Lacks efficiency in null safety management|
|Absence of invariant arrays||Challenge in the binary compilation|
|Absence of SAM Conversions||-|
From the above comparison table, we can conclude that Kotlin is a better programming language than Scala.
Let us first see Kotlin’s interoperability with Java
Since Kotlin is designed and developed to be interoperable with Java, you can call the existing Java code from Kotlin in a natural manner. Similarly, you can use Kotlin code from Java smoothly. In the Kotlin programming language, Java declaration types are treated specially and called platform types. These platform types are safe because null checks are relaxed for them. Kotlin treats getters and setters as properties using the same name in case they exist in a Java class. Similarly, Boolean accessor methods are treated as properties in Kotlin.
Coroutines are light-weight threads, which help in improving application performance. In an Android-based app, they help in managing long-running tasks and providing safety. Using the Coroutines, you can write asynchronous code, which is readable and maintainable perfectly. When compared with default Java threads, the Coroutines in Kotlin Programming language consumes less memory and time as well. Coroutines also make computation easier without blocking the other threads.
As discussed earlier in this article, Android has complete support for Kotlin. It has been announced by Google in 2019 that Kotlin is its preferred language for Android development. Several applications have already developed using Kotlin and Android combination.
Here are some of the benefits, which can be achieved using the potential combination of Kotlin and Android.
Now let us see the career scope in Kotlin.
Since Kotlin is the preferred language for android, many companies are moving towards Kotlin overlooking Java. In just eight months the usage of Kotlin has doubled jumping from 7% to 14%. This phenomenal increase is attributed to Google’s announcement of making Kotlin its preferred language. Besides, there are indications that most of Google’s projects will be done in Kotlin as it increases its investments in Kotlin. Major organizations such as Amazon Web Services, Pinterest, Coursera, Prezi, Basecamp, Netflix, and Uber, etc. have already adopted Kotlin. Given all these positives, you can expect an excellent scope in Kotlin.
Joining the Kotlin course at Mindmajix will certainly enable you to learn all the nuances of Kotlin and makes you an expert in building Android applications. Once the course is completed, you will be eligible for the Kotlin certification, which provides you with an edge in the job market.
