0x00: about kotlin

  • kotlin it's a programming language that support both functional programming and oriented-object paradigms and runs at JVM
  • i've been learning this language because this is useful to develop mobile applications in android studio and i don't like java so much. so, this notes are focused on android development

0x01: kotlin basics

  • before we start, is necessary to know how to implement the basic structures on programming on kotlin.

  • variable declaration:

    val mutable   : String = "ghupasselongo"
var unmutable : Strng  = "ghu0xf"
var guessType          = "aero"
    - strings:

    val mutable   : String = "ghupasselongo"
var unmutable : Strng  = "ghu0xf"
var guessType          = "aero"

  • numbers

    val mutable   : String = "ghupasselongo"
var unmutable : Strng  = "ghu0xf"
var guessType          = "aero"

  • bools

    val mutable   : String = "ghupasselongo"
var unmutable : Strng  = "ghu0xf"
var guessType          = "aero"

  • static fields

    val mutable   : String = "ghupasselongo"
var unmutable : Strng  = "ghu0xf"
var guessType          = "aero"

  • collections

    val mutable   : String = "ghupasselongo"
var unmutable : Strng  = "ghu0xf"
var guessType          = "aero"
