Scala Mutable SortedSet filter() method

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

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

Return Type: It returns a TreeSet containing all the elements of the SortedSet which satisfies the given predicate.

Example #1:

// Scala program of filter()
// method
import scala.collection.mutable.SortedSet

// Creating object
object GfG
{

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

        // Creating a SortedSet
        val s1 = SortedSet(5, 12, 3, 13)

        // Applying filter method
        val result = s1.filter(_ < 10)

        // Displays output
        println(result)

    }
}

Output:

TreeSet(3, 5)

Example #2:

// Scala program of filter()
// method
import scala.collection.mutable.SortedSet

// Creating object
object GfG
{

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

        // Creating a SortedSet
        val s1 = SortedSet(5, 12, 3, 13)

        // Applying filter method
        val result = s1.filter(_ < 3)

        // Displays output
        println(result)

    }
}

Output:

TreeSet()
