scala string to lower case

To convert a string to lowercase in Scala, you can use the toLowerCase method provided by the String class. Here's an example:

val str = "Hello World"
val lowercaseStr = str.toLowerCase

In this code, the toLowerCase method is called on the str variable, which contains the string "Hello World". The result is assigned to the lowercaseStr variable, which will contain the lowercase version of the string.

That's all you need to do to convert a string to lowercase in Scala.
