.lowercase()

The .lowercase() method in Kotlin changes all characters in a string to lowercase. It does not modify the original string, rather it returns a new transformed string. This is useful when case-sensitive operations are performed.

Syntax

String.lowercase()

• String: The string to be converted to lowercase.

Example

The following example shows how to use the .lowercase() method on a string:

fun main() {
  val originalString = "Hello, World!"
  val newString = originalString.lowercase()
  println("Original String: $originalString")
  println("Lowercased String: $newString")
}

The above code will return the following output:

Original String: Hello, World!
Lowercased String: hello, world!
