Scala BitSet &~() method with example

Last Updated : 4 May, 2020
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 
// 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 
// 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)
