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
      
    
Output:
BitSet(7)
