In Scala ListSet, takeWhile() method is utilized to find the elements from the list as long as the stated condition is satisfied.

Method Definition: def takeWhile(p: (A) => Boolean): ListSet[A] Return Type: It returns the elements from the list as long as the stated condition is satisfied.

Example 1:

Scala

// method
import scala.collection.immutable._

// Creating object
object GfG
{

    // Main method
    def main(args:Array[String])
    {

        // Creating a listset
        val m1 = ListSet(1, 2, 3, 4, 5, 7)


        // Applying takeWhile method
        val result = m1.takeWhile(_ > 3)

        // Displays output
        println(result)

    }
}

Output:

ListSet(4, 5, 7)

Example 2:
