Welcome to the Kotlin Tutorials for Beginners for Android. Kotlin has been announced as Official Android Language at Google I/O 2017. Does it means Java will die? No, Java wont die but Kotlin is more powerful than Java for making Android Apps. So lets begin the series of Kotlin Programming right from the next video. And install Java JDK for windows and Macosx and also install Intellij idea created by JetBrains.

Requirements
  • No previous knowledge on kotlin required. We will dive deep from very basics.
  • Just a computer running Microsoft Windows/Linux/Mac running OS.We will install JDK + IntelliJ with every steps explained and shown.
Description

>> Develop skills in Kotlin from scratch, the most beautiful modern programming language based on Java and now used for Android!

>> Expand your expertise as a Java/Android Developer and improve the quality of your code!

We begin with basics such that the beginners get a good grab over the language. There will be quizzes and coding challenges so that you test your learning.
Then we will get along with the intermediate level and create Android Apps and integrate Kotlin with Java.

The course goes on as:

  • Installation of the development environment 
  • Understanding how program flow works in Kotlin. 
  • Variables & Opertors. 
  • Logic and making decision.
  • Binary and hexadecimal numbers.
  • Loops. 
  • Working with files.
  • Functions.
  • OOPs in Kotlin.
  • Data Classes.
  • Collections and types of collections: List, Arrays, Map and Set
  • Lambdas and High Level Function
  • Predicates
  • Multi Processing.Information hiding principles and generics.

At last, get started with your first Kotlin Android App.

Give us the review and feedback to improve the course.

Once you understand the concept of OOPs explained here for Kotlin, this basic paradigm being same for all other languages, you can master others too!
    (Java, PHP, C#, C++)

This course will be shaped as you want it to be. There will be more contents based on your reviews and feedback. Help this start reach heights with your valuable opinions.

Get in now and be the part!

Who this course is for:
  • You should be eager to learn this awesome programming language!
  • You do not need programming skills, we will start from scratch, heading towards intermediate and then to advanced topics.
  • Anyone who wants to use kotlin for existing and new Android Apps, get this for yourself.

It was good for my first Kotlin course to go through. I think a couple topics were left unresolved but for the most part I got a very good overview of Kotlin. It seems for me that even though the instructors first language is not English may be the reason that his explanations are more simplistic and less complicated. I actually like that.
