Scala BitSet addString() 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 addString() method is utilised to append all elements of this traversable or iterator to a string builder.

Method Definition: def addString()

Return Type: It returns the string builder b to which elements were appended.

Example #1:

// Scala program of Bitset addString
// method
import scala.collection.immutable.BitSet

// Creating object
object GfG
{

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

        val bitSet: BitSet = BitSet(0, 1, 2, 3)
        val b = new StringBuilder()


        // Applying BitSet addString() function
        val  bs1 = bitSet.addString(b)

        // Displays output
        println(bs1)

    }
}

Output:

0123

Example #2:

// Scala program of Bitset addString
// method
import scala.collection.immutable.BitSet

// Creating object
object GfG
{

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

        val bitSet: BitSet = BitSet(11, 22, 33)
        val b = new StringBuilder()


        // Applying BitSet addString() function
        val  bs1 = bitSet.addString(b)

        // Displays output
        println(bs1)

    }
}

Output:
