Kotlin Video Series – String (Part 2)

This is the fifth part of the video series on Kotlin language.
Read and watch the other parts here.

In this video, we discuss string comparison and string templates.

String comparison is a breeze in Kotlin. We can use == to compare two string literals.

fun main(args:Array<String>){
  var lang1 = "java"
  var lang2 = "Java"
  println(lang1 == lang2)
}

Strings can be compared using the .compareTo method too, which gives you an option to compare the values ignoring the case, like this.

  println(lang1.compareTo(lang2,true) == 0)

String templates allow you to embed values in a string using ${expression}

   var comments = "$lang1 is cool"
   println(comments)
   comments = "${lang2} is cool"
   println(comments)
