Why is kotlin awesome?

Because unlike java it doesn’t sucks.

For example kotlin have properties:

var test = "hello"
  get(){
    return field + " world"
  }
  set(value){
    field = value
  }

Does this look like the classical Java shit with getters and setters?

Yes it does, but…

You can use it like this

test = "what a shitty"
println(test)

OUTPUT:

what a shitty world

This is the most awesome thing ever, as it makes everything more simple, no more:

dog.getOwner().getDad().setName("Patrick")

This just becomes:

dog.owner.dad.name = "Patrick"

That’s way more synthetic and clear.

Plus it keeps its interoperability with Java since on compile-time it get translated to a private field with public getter and setter.

Another super nice thing is that kotlin automatically turn Java getters and setters into Kotlin properties.

So from Kotlin you can reference a Java class and if it has the correct naming convention you can use its properties without the need to call getters and setters.

Protip:

If the get or the set are single lines you can make it shorter by writing it like this:

var test = "hello"
  get() = field + " world"
  set(value){ field = value }
