In Scala mutable collections, +() method is utilized to create a new SortedSet with an additional element unless the element is already present.
Method Definition: def +(elem: A): SortedSet[A]
Return Type: It returns a new SortedSet with an additional element unless the element is already present.
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( 4 , 8 , 9 , 1 , 7 )
// Applying +() method
val result = s 1 .+( 5 )
// Display output
print(result)
}
} |
Output:
TreeSet(1, 4, 5, 7, 8, 9)
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 )
// Applying +() method
val result = s 1 .+( 100 )
// Display output
print(result)
}
} |
Output:
TreeSet(1, 12, 23, 41, 43, 72, 100)
