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 with an additional element, unless the element is already present.
Method Definition: def +() Return Type: It returns a new set that contains all elements of this set.
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 bitSet: BitSet = BitSet(0, 1, 2, 3) 
        println(s"Elements in Bitset are = $bitSet") 

        // Applying BitSet +() function 
        val bs1: BitSet = bitSet + 10 + 11
        
        // Displays output 
        println(bs1) 
    
    } 
} 
Output:
Elements in Bitset are = BitSet(0, 1, 2, 3)
BitSet(0, 1, 2, 3, 10, 11)
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 bitSet: BitSet = BitSet(0, 1, 2, 3 ) 
        println(s"Elements in Bitset are = $bitSet") 

        // Applying BitSet +() function 
        val bs1: BitSet = bitSet + 1 + 2 + 3
        
        // Displays output 
        println(bs1) 
    
    } 
} 
Output:
Elements in Bitset are = BitSet(0, 1, 2, 3)
BitSet(0, 1, 2, 3)
