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 compute the difference of this bitset and another bitset by performing a bitwise “and-not”.

Method Definition: def &~()

Return Type: It returns a new bitset consisting of all elements that are not contained in given 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(41, 12, 23, 43, 1, 72)
        val b2: BitSet = BitSet(1, 100, 55, 32, 23)

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

        // Displays output
        println(bs1)

    }
}

Output:

BitSet(12, 41, 43, 72)

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(41, 12, 23, 43, 1, 72)

        // Applying BitSet &~() function
        val bs1: BitSet = b1 &~ BitSet(1, 100, 5, 12, 23)

        // Displays output
        println(bs1)

    }
}

Output:

BitSet(41, 43, 72)
