Method Definition: def head: A
Return Type: It returns the first element of the SortedSet.
Example #1:
// Scala program of head() // method import scala.collection.mutable.SortedSet
// Creating object object GfG
{ // Main method
def main(args : Array[String])
{
// Creating a SortedSet
val s 1 = SortedSet( 12 , 15 , 14 , 13 )
// Applying head method
val result = s 1 .head
// Display output
println(result)
}
} |
Output:
12
Example #2:
// Scala program of head() // method import scala.collection.mutable.SortedSet
// Creating object object GfG
{ // Main method
def main(args : Array[String])
{
// Creating a SortedSet
val s 1 = SortedSet( 6 , 7 , 5 , 4 , 1 )
// Applying head method
val result = s 1 .head
// Display output
println(result)
}
} |
Output:
