Scala BitSet ++[B](that: GenTraversableOnce[B]) method with example

Scala Bitsets are sets of non-negative integers which are represented as variable-size arrays of bits packed into 64-bit words. The ++[B](that: GenTraversableOnce[B])
method is utilised create a bitset containing the elements from the left hand operand followed by the elements from the right hand operand.

Method Definition: def ++[B](that: GenTraversableOnce[B])

Return Type: It returns a new bitset which contains all elements of this bitset.

Example #1:

// Scala program of Bitset ++
// method
import scala.collection.immutable.BitSet

// Creating object
object GfG
{

    // Main method
    def main(args:Array[String])
    {

        val b1: BitSet = BitSet(0, 1, 2, 3)
        val b2 = List("a", "B")

        // Applying BitSet ++() function
        val bs1 = b1 ++ b2

        // Displays output
        println(bs1)

    }
}

Output:

Set(0, 1, a, 2, B, 3)

Example #2:

// Scala program of Bitset ++
// method
import scala.collection.immutable.BitSet

// Creating object
object GfG
{

    // Main method
    def main(args:Array[String])
    {

        val b1: BitSet = BitSet(0, 1, 2, 3 )
        val b2 = List("A" )

        // Applying BitSet ++() function
        val bs1 = b1 ++ b2

        // Displays output
        println(bs1)

    }
}

Output:

Set(0, 1, A, 2, 3)
