Scala TreeSet toSeq() method with example

The toSeq() method is utilized to return a seq consisting of all the elements of the TreeSet.

Method Definition: def toSeq: Seq[A]

Return Type: It returns a seq consisting of all the elements of the TreeSet.

Example #1:

// Scala program of toSeq()
// method

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

// Creating object
object GfG
{

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

        // Creating TreeSet
        val t1 = TreeSet(1, 2, 3, 4, 5, 6)

        // Print the TreeSet
        println(t1)

        // Applying toSeq method
        val result = t1.toSeq

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

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

    }
}

Output:

TreeSet(1, 2, 3, 4, 5, 6)
Elements in the Seq: 1 2 3 4 5 6

Example #2:

// Scala program of toSeq()
// method

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

// 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 toSeq method
        val result = t1.toSeq

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

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

    }
}

Output:

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