BitSet +() Method in Scala

By IncludeHelp Last updated : November 09, 2024

BitSet in Scala is a special collection of positive integers. Scala programming language has a huge library containing a lot of utility functions to help working with data structure easy.

BitSet +() Method

The +() method in Scala is used to add a new non-negative integer to an existing BitSet in Scala.

The new BitSet will contain all elements of the existing BitSet and element that is added to it by the method.

Syntax

BitSet_Name + (element)

Return Type

The function will return a new BitSet with elements of the previous bitSet plus new elements.

Example 1

Program to illustrate the working of our + method to add an element to a BitSet.

import scala.collection.immutable.BitSet

object MyObject {
    def main(args: Array[String]): Unit = {
        val BitSet1 = BitSet(3, 1, 5, 8, 0)
        println("BitSet initially : " + BitSet1)
        
        // Adding new element using + method     
        val newBitSet = BitSet1 + 32
        println("BitSet after adding new element : " + newBitSet)
    }
}

Output

BitSet initially : BitSet(0, 1, 3, 5, 8)
BitSet after adding new element : BitSet(0, 1, 3, 5, 8, 32)

Example 2

Program to illustrate the working of our + method to add multiple elements to a BitSet.

import scala.collection.immutable.BitSet

object MyObject {
    def main(args: Array[String]): Unit = {
        val oriBitSet = BitSet(6, 1, 9, 3, 0)
        println("BitSet initially : " + oriBitSet)
        
        // Adding new elements using + method     
        val newBitSet = oriBitSet + 2 + 5
        println("BitSet after adding new elements : " + newBitSet)
    }
}

Output

BitSet initially : BitSet(0, 1, 3, 6, 9)
BitSet after adding new element : BitSet(0, 1, 2, 3, 5, 6, 9)
