Here, we will learn about the BitSet ++() method in Scala along with syntax and examples.

BitSet in Scala is a special collection of positive integers. Scala programming language has a huge library containing a lot of utility functions to help working with data structure easy.
BitSet ++() Method
The ++() method in Scala is used to add two collections in scala. The addition is saved to a new BitSet.
One of the two collections to be added must be a BitSet otherwise the method will return a type mismatch error.
Syntax:
BitSet = BitSet_Name ++ collection_Name
Return type:
The method returns a new BitSet with all elements from the two collections passed to the method.
Program 1: Program to illustrate the working of ++ method in Scala by adding two BitSets in Scala.
// Scala program to illustrate the working of ++ method
import scala.collection.immutable.BitSet
object MyObject{
def main(args: Array[String]) {
val BitSet1 = BitSet(4, 1 ,7, 9, 3)
val BitSet2 = BitSet(18, 100, 91, 66)
println("BitSet1 : " + BitSet1)
println("BitSet2 : " + BitSet2)
// Adding new elements using + method
val newBitSet = BitSet1 ++ BitSet2
println("Addition BitSet : " + newBitSet)
}
}
Output:
BitSet1 : BitSet(1, 3, 4, 7, 9)
BitSet2 : BitSet(18, 66, 91, 100)
Addition BitSet : BitSet(1, 3, 4, 7, 9, 18, 66, 91, 100)
Program 2: Program to illustrate the working of ++ method in Scala by adding one bitSet and one collection.
// Scala program to illustrate the working of ++ method
import scala.collection.immutable.BitSet
object MyObject{
def main(args: Array[String]) {
val BitSet1 = BitSet(4, 1 ,7, 9, 3)
val collection1 = Vector(18, 100, 91, 66)
println("BitSet1 : " + BitSet1)
println("collection1 : " + collection1)
// Adding new elements using + method
val newBitSet: BitSet = BitSet1 ++ collection1
println("Addition BitSet : " + newBitSet)
}
}
Output:
BitSet1 : BitSet(1, 3, 4, 7, 9)
collection1 : Vector(18, 100, 91, 66)
Addition BitSet : BitSet(1, 3, 4, 7, 9, 18, 66, 91, 100)
