Scala ListSet count() method with Example

In Scala ListSet, count() method is utilized to count the number of elements of the listSet which satisfy a stated predicate.

Method Definition: def count(p: (A) => Boolean): ListSet[A] Return Type: It returns the count of number of elements of the listset which satisfy the given predicate. 

Example 1:

Scala

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

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

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

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

        // Displays output
        println(result)

    }
}

Output:

4

Example 2:

Scala

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

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

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

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

        // Displays output
        println(result)

    }
