What is trim() in Scala?

The trim() method is used to remove all the leading and trailing spaces that are present in the string. For example, if the string looks like, " Hello World " then there is a lot of empty space before the term “Hello” and after the term “World”.

The method trim() is used to remove these spaces.

Syntax

Code

Let’s understand it better with a coding example.

object Main extends App {
  // apply trim on a string
   val data = "     Hello World ".trim()     
  // Display resultant data
  println(data)
  val data1 = "Lord of the rings   ".trim()     
  // Display resultant data
  println(data1)
}
