In Scala mutable collection, ++() method is utilized to add elements of one SortedSet to another SortedSet.
Method Definition: def ++(elems: A): SortedSet[A]
Return Type: It returns a new TreeSet containing elements of both the SortedSets.
Example #1:
// Scala program of ++() method import scala.collection.mutable.SortedSet
// Creating object object GfG
{ // Main method
def main(args : Array[String])
{
// Creating a SortedSet
val s 1 = SortedSet( 1 , 3 , 5 )
val s 2 = SortedSet( 2 , 4 , 6 )
// Applying ++() method
val result = s 1 ++ s 2
// Display output
print(result)
}
} |
Output:
TreeSet(1, 2, 3, 4, 5, 6)
Example #2:
// Scala program of ++() method import scala.collection.mutable.SortedSet
// Creating object object GfG
{ // Main method
def main(args : Array[String])
{
// Creating a SortedSet
val s 1 = SortedSet( 41 , 12 , 23 , 43 , 1 , 72 )
val s 2 = SortedSet( 1 , 100 , 5 , 12 , 23 )
// Applying ++() method
val result = s 1 ++ s 2
// Display output
print(result)
}
} |
Output:
TreeSet(1, 5, 12, 23, 41, 43, 72, 100)
