Java is a famous, stable, strong programming language. From a long time use java for Android development. But why need kotlin? What is the benefit of kotlin?

Generally kotlin is more power full then Java for some extra additional feather. Basically Kotlin is a language that inherits from java. Java runs by JVM and Kotlin also runs by JVM. But Kotlin can run with JS and some other language. It is a biggest enhancement of Kotlin.

1. Kotlin syntax is 100 times easier then java. But it looks like mixed of java and python.
2. Kotlin use JVM and some anther language compiler. So that it is using in multi platform.
3. Kotlin Coroutine is a great enhancement of Kotlin. Coroutine is use lite bit asynchronous task.
4. Kotlin can save development time for easy syntax.
5. Kotlin can use for Android, web, ios and cross platform also.

Now days many library make by kotlin that use kotlin power. Some additional feather decrease developer pressure and increase productivity. So kotlin is declared by google as official language of Android.

As a beginner what is the best option choice Java or Kotlin?

Firstly you should learn Java properly. If you properly learned java you can move Java to Kotlin within 7 days. After learning Java your can move Java to Python less then 7 days(Basics Python to Advance Python syntax and concept but not everything ). But Python to move Java is very difficult.

Secondly when you will learn Android your should read different of projects. Most of old projects write in Java. So your must need to read Java. But most of new projects write in Kotlin so your should read Kotlin.

If your get job any software company, you must maintain there previous projects that’s probably write in Java. So Your must need to learn Java and Kotlin also.
