The count() method is utilized to count pair of keys in the SortedMap.
Method Definition: def count(p: ((A, B)) => Boolean): Int
Return Type: It returns the number of keys present in the SortedMap that satisfies the given predicate.
Example #1:

object GfG
{
def main(args : Array[String])
{
val m 1 = SortedMap( "geeks" - > 5 , "for" - > 3 , "cs" - > 5 )
val result = m 1 .count(z => true )
println(result)
}
}

Example #2:
import scala.collection.SortedMap
object GfG
{
def main(args : Array[String])
{
val m 1 = SortedMap( "geeks" - > 5 , "for" - > 3 , "geeks" - > 5 )
val result = m 1 .count(z => true )
println(result)
}
}
