Scala Bitsets are sets of non-negative integers which are represented as variable-size arrays of bits packed into 64-bit words. The ++:[B](that: TraversableOnce[B]) method is utilised create a collection containing the elements from the left hand operand followed by the elements from the right hand operand.
Method Definition: def ++:[B](that: TraversableOnce[B])
Return Type: It returns a new bitset which contains all elements of this bitset followed by all elements of that.
Example #1:
Scala
Scala
// Scala program of Bitset ++
// method
import scala.collection.immutable.BitSet
import scala.collection.mutable.LinkedList
// Creating object
object GfG
{
// Main method
def main(args:Array[String])
{
val b1 = BitSet(0, 1, 2, 3)
val b2 = LinkedList(100)
// Applying BitSet ++() function
val bs1 = b1 ++: b2
// Displays output
println(bs1)
}
}
Output:
Example #2:
LinkedList(0, 1, 2, 3, 100)
// Scala program of Bitset ++
// method
import scala.collection.immutable.BitSet
import scala.collection.mutable.LinkedList
// Creating object
object GfG
{
// Main method
def main(args:Array[String])
{
val b1 = BitSet(11, 22, 33)
val b2 = LinkedList("A", "B")
// Applying BitSet ++() function
val bs1 = b1 ++: b2
// Displays output
println(bs1)
}
}
Output:
LinkedList(0, 1, 2, 3, A, B)
