BitSet drop() Method in Scala

By IncludeHelp Last updated : November 14, 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 drop() method

BitSet drop() method is used to delete first n elements from the BitSet.

Syntax

bitset_name.drop(n)

Parameters

It accepts a single parameter (n) which is the number of elements to be dropped.

Return Type

Returns a BitSet which contains the elements that remained after dropping.

Example 1

Program to illustrate the working of drop method in Scala

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

import scala.collection.immutable.BitSet

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

Output

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

Explanation

In the above code, we have created a BitSet named myBitset in Scala. Then dropped 3 elements using the drop method and printed the resulting BitSet.

Example 2

Program to illustrate the working of drop method in Scala

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

import scala.collection.immutable.BitSet

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

Output

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

Explanation

In the above code, we have created a BitSet named myBitset in Scala. Then dropped 6 elements using the drop method which is greater than the size of the array. Here, the method returns an empty BitSet. At last, we will print the resulting BitSet.
