{ // Main method
def main(args:Array[String])
{
// Creating sets
val s1 = Set(1, 2, 3, 4, 5)
// Applying count method
val result = s1.count(z=>true)
// Displays output
println(result)
}
} |
Output:
5
Example #2:
// Scala program of count() // method // Creating object object GfG
{ // Main method
def main(args:Array[String])
{
// Creating sets
val s1 = Set()
// Applying count method
val result = s1.count(z=>true)
// Displays output
println(result)
