Which method to call in order to convert given string to UpperCase in Kotlin?-CodePudding

Given a String:

val myString: Any = "baa baa bLack shEEp"

I would like to have a new string (as myString is immutable of course) containing:

BAA BAA BLACK SHEEP

Checked in https://kotlinlang.org/api/latest/jvm/stdlib/kotlin.text/to-upper-case.html But it says it is deprecated. I must say - it works, but probably there's a reason for that. Any idea?

CodePudding user response：

the method toUpperCase() is indeed deprecated. here's an example how to achieve upper case:

val myString: Any = "baa baa bLack shEEp"
if (myString is String){
    println(myString.uppercase())
}

CodePudding user response：

simple you just need to do this:

val myString = "baa baa bLack shEEp" 
println(myString.uppercase())
