TreeSet class, the count() method is utilized to count the number of elements in the TreeSet that satisfies a given predicate.
Method Definition: def count(p: (A) => Boolean): Int Return Type: It returns the count the number of elements in the TreeSet that satisfies a given predicate.Example #1:
// Scala program of count()
// method
// Import TreeSet
import scala.collection.immutable._
// Creating object
object GfG
{
// Main method
def main(args:Array[String])
{
// Creating TreeSet
val t1 = TreeSet(2, 1, 3, 4, 5)
// Print the TreeSet
println(t1)
// Applying count() method
val result = t1.count(x => {x % 2 == 0})
// Display output
print("Number of even element in the TreeSet: " + result)
}
}
Output:
Example #2:
TreeSet(1, 2, 3, 4, 5) Number of even element in the TreeSet: 2
// Scala program of count()
// method
// Import TreeSet
import scala.collection.immutable._
// Creating object
object GfG
{
// Main method
def main(args:Array[String])
{
// Creating TreeSet
val t1 = TreeSet(2, 1, 3, 4, 5)
// Print the TreeSet
println(t1)
// Applying count() method
val result = t1.count(x => {x % 2 != 0})
// Display output
print("Number of odd element in the TreeSet: " + result)
}
}
Output:
TreeSet(1, 2, 3, 4, 5) Number of odd element in the TreeSet: 3
