code

// Scala program of count()
// method
import scala.collection.SortedMap
  
// Creating object
object GfG
  
    // Main method
    def main(args:Array[String])
    {
      
        // Creating a SortedMap
        val m1 = SortedMap("geeks" -> 5, "for" -> 3, "cs" -> 5)
          
        // Applying count method
        val result = m1.count(z=>true)
          
        // Displays output
        println(result)
