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 create a new set by adding all elements contained in another collection to this set, omitting duplicates.
Method Definition: def ++() Return Type: It returns a new set with the given elements added,
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) 
        val b2: BitSet = BitSet(4, 5, 6, 7) 

        // Applying BitSet ++() function 
        val bs1: BitSet = b1 ++ b2
        
        // Displays output 
        println(bs1) 
    
    } 
}
Output: 
BitSet(0, 1, 2, 3, 4, 5, 6, 7)
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 ) 
        val b2: BitSet = BitSet(15, 16, 17 ) 

        // Applying BitSet ++() function 
        val bs1: BitSet = b1 ++ b2
        
        // Displays output 
        println(bs1) 
    
    } 
}
Output: 
BitSet(0, 1, 2, 3, 15, 16, 17)
