What the Heck is Kotlin???

What the Heck is Kotlin ???


Programming is that type of Daily Soap on Indian TV, which can change/update at any time of the day or any day of the year !!!


So, you have to be super ready as a developer to adapt any new language introduced in your field. And this time its for Android Developers and the freshly baked language for them is, none other than Kotlin.
Lets go through some of the things that you as a developer needs to keep in mind while even moving towards trying this new stuff.

0) What is Kotlin?

The Super Important Question Right Now!!!
 

Kotlin is an Android-compatible language that is concise, expressive, and designed to be type- and null-safe. It works with the Java language seamlessly, so it makes it easy for developers who love the Java language to keep using it but also incrementally add Kotlin code and leverage Kotlin libraries. Also, many Android developers have already found that Kotlin makes development faster and more fun, so we want to better support these Kotlin users.


1) Why prefer Kotlin over Java?



You should prefer Kotlin over Java!!! No, its not like that. But you should be clear and precised about WHY. This bold thing “WHY” can make your life easier if you continue to raise it before doing or implementing anything.
Q. Why Kotlin?
A. Basically Kotlin offers something which Java does not provide you from years of its existence. But I think this is the Job of new and different languages to come up with something that the previous or current languages does not offer.
Here Kotlin offers or you can say fixes some of the issues of Java, like
  • - Null references are controlled by the type system.
  • - No raw types
  •  - Arrays in Kotlin are invariant
  •  - Kotlin has proper function types, as opposed to Java’s SAM-conversions
  • - Use-site variance without wildcards
  • - Kotlin does not have checked exceptions

  • 2) What I have to do to get a sneak peek into Kotlin?



So the pivot of all the discussion comes to this basic point, that HOW can i get some of the Kotlin in my Environment and have some basic knowledge of it.
The Easiest way I know is this:
Step 1: Open Android Studio, Go to File -> Settings -> Plugins.
Step 2: In Plugin Section, look at the bottom section and click that “Install JetBrains plugin…” button.



Step 3: Now Search “Kotlin” or Scroll down to the letter ‘k’ and find “Kotlin” there and hit that Green Install button and let Studio do the downloading part.
Step 4: Wait…Wait…till it finishes.
Step 5: Now create a New Activity in your Android Studio and open MainActivity.java File.
Step 6: With the help of some keys of your keyboard, press Ctrl+Alt+Shift+K and it will show one dialog which says — “Convert Java Files into Kotlin” and hit OK.
Step 7: Kaboom!!! Welcome to the Kotlin and its MainActivity.kt File.

Let’s keep it short….again

Let’s keep it short….again The world is full of people who are full of Fear of Failure which doesn’t allow them to move steadily and think positively. But many of them don’t know that Fear is a Big Liar. Because Fear shows you fake reality about your own self that — ”You can’t do this thing”. Instead people should fake their fear by repeatedly saying this — ”At least I can try!!!” Because there is no sense at all to not do the particular thing just because you have never done it earlier. Try Again…Fail Again…Fail Better!!!😎 Kudossss To Fearless You…
