Scala immutable TreeSet toArray() method

In Scala immutable TreeSet class the toArray() is utilised to return an array consisting of all the elements of the TreeSet.

Method Definition: def toArray: Array[A]

Return Type: It returns an array consisting of all the elements of the TreeSet.

Example #1:

// Scala program of toArray()
// method

// Import TreeSet
import scala.collection.immutable._

// Creating object
object GfG
{

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

        // Creating TreeSet
        val t1 = TreeSet(3, 1, 5, 2, 4)

        // Print the TreeSet
        println(t1)

        // Applying toArray method
        val result = t1.toArray

        // Display output
        print("Elements in the array: ")

        for(elem <- result)
            print(elem + " ")

    }
}

Output:

TreeSet(1, 2, 3, 4, 5)
Elements in the array: 1 2 3 4 5

Example #2:

// Scala program of toArray()
// method

// Import TreeSet
import scala.collection.immutable._

// Creating object
object GfG
{

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

        // Creating TreeSet
        val t1 = TreeSet("u", "a", "i", "o", "e")

        // Print the TreeSet
        println(t1)

        // Applying toArray method
        val result = t1.toArray

        // Display output
        print("Elements in the array: ")

        for(elem <- result)
            print(elem + " ")

    }
}

Output:

TreeSet(a, e, i, o, u)
Elements in the array: a e i o u
