when condition with ignore case in kotlin

Question

I know we can write if, else if, else if with a ignore case.

if (someString.equals("otherString", ignoreCase = true)) {
}

I am very curious about this, how to write a when(in Java it is a switch) condition with ignoring the case.

Answer 1

There are a couple of options:

1. Translate strings to lower (or upper) case:

   when (someString.toLowerCase()) {
       "otherString1".toLowerCase() -> { /*...*/ }
       "otherString2".toLowerCase() -> { /*...*/ }
   }
   

2. Directly use equals method:

    when {
        someString.equals("otherString1", ignoreCase = true) -> { /*...*/ }
        someString.equals("otherString2", ignoreCase = true) -> { /*...*/ }
    }
