Should java developer in android worry with Introduction of Kotlin:
Before going to the answer of the question, I would like to list few parameters.
It combines OO and functional features and is focused on interoperability and seamless support for mixed Java+Kotlin projects, safety, clarity and tooling support.
Its primary development is from a team of JetBrains programmers .
A: Why Kotlin
Kotlin is built with experiences from Industry to handle the practical issues due to programming languages.
Nothing to adopt, Opensource.
Can use java libraries and vice versa.
Null pointer safety (This has been the biggest headache for the developer. Due to programming error, hw/ sw error, version incompatibility etc)..
Lean Syntax: Class, function defining made easier.
Unchecked Exception and many more…
Comparision of Java vs Kotlin from official link of kotlin:
I would say programmer shouldnt worry with introduction of Kotlin. Programming logic are always the same, Its just syntax to learn and they are easy. This increase the productivty and popularity of Android.
C: Will the java be phased out: Nope
D: Will the app look different: Nope
