toLowerCase() FUNCTION

toLowerCase() Function

The toLowerCase() Function is used to convert all the characters/letters of the String in lower case.

Example :

fun main() {

    var x = "HeLLo"
    var y = x.toLowerCase()
        
    println("The String in lower case is : "+y)
}

Output :

The String in lower case is : hello

In the above code, we have declared a String 'HeLLo', in which the letters 'H' and two 'L's are in upper case.

var x = "HeLLo"

So, we have used the 'toLowerCase()' Function to convert them to lower case and assign to a variable 'y'.

var y = x.toLowerCase()
