Kotlin Basics (function (fun max(a: Int, b: Int) : Int{} (statement x…

- - - - expression has its own value
        
        e.g: fun max(a: Int, b: Int) : Int = if (a > b) a else b
        
        with braces has block body
        
        without braces has expression body
        
        without return-type
        
        e.g fun max(a: Int, b: Int) = if (a>b) a else b
        
        because of type inference
        
        compile can analyze
      - statement doesnt have its own value
- - - - implicitily is Int
  - - - error type mismatch
  - - - println("The name is: ${ args[0] }")
      - double quotes within an expression
        
        println("The name is: ${ if(args.size > 0) args[0] else "someone"}")
- - - - getter and setter is created
      - val is read-only
        
        only created get
      - calling getter in Kotlin
        
        person.name
        
        it call property directily
      - calling setter in Kotlin
        
        person.isMarried = false
      - creating object
        
        Person("Juliano", true)
- - - - when(color) { Color.RED -> "Richard"}
        
        e.g using when with enum
- - - - its not changed after is check
      - property class has to be val and cannot has custom accessor
- - - - .. defines a range
