In Scala Stack class
, the count() method is utilized to count the number of elements in the stack 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 stack that satisfies a given predicate.
Example #1:
import scala.collection.mutable. _
object GfG
{
def main(args : Array[String])
{
val s 1 = Stack( 1 , 2 , 3 , 4 , 5 )
println(s 1 )
val result = s 1 .count(z => true )
print( "Number of element in stack: " + result)
}
}
|
Output:
Stack(1, 2, 3, 4, 5)
Number of element in stack: 5
Example #2:
import scala.collection.mutable. _
object GfG
{
def main(args : Array[String])
{
val s 1 = Stack( 1 , 2 , 3 , 4 , 5 )
println(s 1 )
val result = s 1 .count(z => {z % 2 == 0 })
print( "Number of element in stack divisible by 2: " + result)
}
}
|
Output:
Stack(1, 2, 3, 4, 5)
Number of element in stack divisible by 2: 2
