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 dropRight() method

BitSet dropRight() method is used to select all elements from the BitSet except last n elements i.e. deletes n elements from right.

Syntax:

BitSet_Name.DropRight(n)

Parameters:

The method accepts a single parameter which is the number of elements to be deleted.

Return Type:

Returns a BitSet which is the contains all the selected elements.

Program 1: Program to illustrate the working of dropRight() method

// Program to illustrate the working of dropRight() method

import scala.collection.immutable.BitSet

object MyObject {
    def main(args: Array[String]) {
        val myBitset = BitSet(6, 1, 2, 9, 4, 8, 3)
        
        println("myBitset : " + myBitset)    
        
        val newBitset = myBitset.dropRight(3)
        
        println("myBitset after deleting 3 elements: " + newBitset)    
    }
}

Output:

myBitset : BitSet(1, 2, 3, 4, 6, 8, 9)
myBitset after deleting 3 elements: BitSet(1, 2, 3, 4)

Program 2: Program to illustrate the working of dropRight() method when n is greater than the size of BitSet.

// Program to illustrate the working of dropRight() method

import scala.collection.immutable.BitSet

object MyObject {
    def main(args: Array[String]) {
        val myBitset = BitSet(6, 1, 2, 9, 4, 8, 3)
    
        println("myBitset : " + myBitset)    
    
        val newBitset = myBitset.dropRight(10)
    
        println("myBitset after deleting 10 elements: " + newBitset)    
    }
}

Output:

myBitset : BitSet(1, 2, 3, 4, 6, 8, 9)
myBitset after deleting 10 elements: BitSet()
