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 dropWhile() method

BitSet dropWhile() method is used to delete the first element that satisfies the given condition and return the remaining BitSet.

Syntax

bitset_name.dropWhile(condition)

Parameters

It accepts a single parameter which is the condition to delete the element.

Return Type

Returns a BitSet which contains elements after deleting.

Example 1

Example to delete element from BitSet using dropWhile() method

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

import scala.collection.immutable.BitSet

object MyObject {
    def main(args: Array[String]): Unit = {
        val myBitset = BitSet(8, 3, 6, 2, 9)
    
        println("myBitset : " + myBitset)    
    
        val newBitset = myBitset.dropWhile(x => {x % 2 == 0} )
    
        println("myBitset after deleting elements using dropWhile : " + newBitset)    
    }
}

Output

myBitset : BitSet(2, 3, 6, 8, 9)
myBitset after deleting elements using dropWhile : BitSet(3, 6, 8, 9)

Explanation

In the above code, we have created a BitSet named myBitset in Scala. Then dropped the first element which is even, then print the resulting BitSet.
