Scala immutable TreeSet toMap() method

In Scala immutable TreeSet class the toMap() method is utilised to return a map consisting of all the elements of the TreeSet.

Method Definition: def toMap[T, U]: Map[T, U]

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

Example #1:

// Scala program of toMap()
// method

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

// 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 toMap method
        val result = t1.toMap

        // Display output
        print("Elements in the Map: " + result)

    }
}

Output:

TreeSet((1, 2), (3, 4), (5, 6))
Elements in the Map: Map(1 -> 2, 3 -> 4, 5 -> 6)

Example #2:

// Scala program of toMap()
// 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", "f"))

        // Print the TreeSet
        println(t1)

        // Applying toMap method
        val result = t1.toMap

        // Display output
        print("Elements in the Map: " + result)

    }
}

Output:

TreeSet((e, f), (i, o), (u, a))
Elements in the Map: Map(e -> f, i -> o, u -> a)
