Course Description
This course covers how to program using Kotlin starting from the basics to hands on exercises, then finalizing with a complete demo, all of which demonstrate the much less complexity of Kotlin than Java.
If you want to become a professional Kotlin developer, then this course is for you.
What you'll learn
After completing this course you will be able to:
kotlin basics:
Understand kotlin variables and datatypes.

Examine added features in For loops.
Remember while loops in java and recognize the similarity with kotlin.
Understand functions (basic with return type, three dots operator, new functions: default arguments and named arguments, extension).
Recall exceptions and examine why checked exceptions are not supported.
Functional programming:
Understand immutability as a new concept.
