Scala BitSet -(elems: Int*) 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 -(elems: Int*) method is utilised takes two or more elements to be removed.

Method Definition: def +()

Return Type: a new collection that contains all elements except one less occurrence of each of the given elements.

Example #1:

// Scala program of Bitset - 
// method  

import scala.collection.immutable.BitSet  

// Creating object  

object GfG  
{  

    // Main method  

    def main(args:Array[String])  

    {  

        val b2: Set[Int] = BitSet(5, 6, 7, 55, 56, 57) - 55 - 56 

        // Displays output  

        println(b2)  

    }  
}

Output:

BitSet(5, 6, 7, 57)

Example #2:

// Scala program of Bitset - 
// method  

import scala.collection.immutable.BitSet  

// Creating object  

object GfG  
{  

    // Main method  

    def main(args:Array[String])  

    {  

        val b2: Set[Int] = BitSet(5, 6, 7) - 5 - 6 - 0

        // Displays output  

        println(b2)  

    }
