Scala BitSet exists() method with example

Scala Bitsets are sets of non-negative integers which are represented as variable-size arrays of bits packed into 64-bit words. The exists() method tests whether a predicate holds for at least one element of this iterable collection.

Method Definition: def exists()

Return Type: It returns false if this iterable collection is empty, otherwise true.

Example #1:

// Scala program of exists()
// method
import scala.collection.immutable.BitSet

// Creating object
object GfG
{

    // Main method
    def main(args:Array[String])
    {

        // Creating BitSet
        val s1 = BitSet(1, 2, 3, 4, 5)


        // Applying exists method
        val result = s1.exists(y => {y % 3 == 0})

        // Displays output
        println(result)

    }
}

Output:

true

Example #2:

// Scala program of exists()
// method
import scala.collection.immutable.BitSet

// Creating object
object GfG
{

    // Main method
    def main(args:Array[String])
    {

        // Creating BitSet
        val s1 = BitSet(1, 2, 3, 4, 5)


        // Applying exists method
        val result = s1.exists(y => {y % 7 == 0})

        // Displays output
        println(result)

    }
}

Output:

false
