Scala BitSet apply() 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 +() method is utilised to test if some element is contained in this set.

Method Definition: def apply()

Return Type: true if elem is contained in this set, false otherwise.

Example #1:

// Scala program of apply()
// 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 apply method
        val result = s1.apply(3)

        // Displays output
        println(result)

    }
}

Output:

true

Example #2:

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

// Creating object
object GfG
{

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

        // Creating BitSet
        val s1 = BitSet(10, 20, 30, 40, 50, 70)

        // Applying apply method
        val result = s1.apply(60)

        // Displays output
        println(result)

    }
}

Output:

false
