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 with an additional element, unless the element is already present.

Method Definition: def +()

Return Type: It returns a new set that contains all elements of this set.

Example #1:

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

// Creating object
object GfG
{

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

        val bitSet: BitSet = BitSet(0, 1, 2, 3)
        println(s"Elements in Bitset are = $bitSet")

        // Applying BitSet +() function
        val bs1: BitSet = bitSet + 10 + 11

        // Displays output
        println(bs1)

    }
}

Output:

Elements in Bitset are = BitSet(0, 1, 2, 3)
BitSet(0, 1, 2, 3, 10, 11)

Example #2:

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

// Creating object
object GfG
{

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

        val bitSet: BitSet = BitSet(0, 1, 2, 3 )
        println(s"Elements in Bitset are = $bitSet")

        // Applying BitSet +() function
        val bs1: BitSet = bitSet + 1 + 2 + 3

        // Displays output
        println(bs1)

    }
}

Output:

Elements in Bitset are = BitSet(0, 1, 2, 3)
BitSet(0, 1, 2, 3)
