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 collection from this collection by removing all elements of another collection.

Method Definition: def --() Return Type: It returns a new collection that contains all elements of the current collection except elems.

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(0, 1, 2, 3, 4, 5) 
        val b2: BitSet = BitSet(4, 5) 

        // Applying BitSet --() function 
        val bs1: BitSet = b1 -- b2
        
        // Displays output 
        println(bs1) 
    
    } 
}

Output:

BitSet(0, 1, 2, 3)

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(0, 1, 2, 3, 15, 16) 
        val b2: BitSet = BitSet(15, 16, 0 ) 

        // Applying BitSet --() function 
        val bs1: BitSet = b1 -- b2
        
        // Displays output 
        println(bs1) 
    
    } 
}

Output:

BitSet(1, 2, 3)
