Scala BitSet ++() 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 +() method is utilised create a new set by adding all elements contained in another collection to this set, omitting duplicates.

Method Definition: def ++()

Return Type: It returns a new set with the given elements added,

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: BitSet = BitSet(4, 5, 6, 7)

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

        // Displays output
        println(bs1)

    }
}

Output:

BitSet(0, 1, 2, 3, 4, 5, 6, 7)

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: BitSet = BitSet(15, 16, 17 )

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

        // Displays output
        println(bs1)

    }
}

Output:

BitSet(0, 1, 2, 3, 15, 16, 17)
