toUpperCase() FUNCTION

toUpperCase() Function

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

Example :

fun main() {

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

Output :

The String in upper case is : HELLO

In the above code, we have declared a String 'HeLLo', in which the letters 'e' and 'o' are in lower case.

var x = "HeLLo"

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

var y = x.toUpperCase()
