Scala ListSet filter() method with example

In Scala ListSet, filter() method is utilized to select all elements of the listSet which satisfies a stated predicate.

Method Definition: def filter(p: (A) => Boolean): ListSet[A]

Return Type: It returns a new listset consisting all the elements of the listset which satisfies the given predicate.

Example 1:

// Scala program of filter()
// method
import scala.collection.immutable._
// Creating object
object GfG
{

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

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

        // Applying filter method
        val result = m1.filter(_>2)

        // Displays output
        println(result)

    }
}

Output:

ListSet(3, 4, 5, 7)

Example 2:

// Scala program of filter()
// method
import scala.collection.immutable._
// Creating object
object GfG
{

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

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

        // Applying filter method
        val result = m1.filter(_<1)

        // Displays output
        println(result)

    }
}

Output:

ListSet()
