Scala TreeSet toString() method with example

The toString() method is utilized to return a string representation of the TreeSet object.

Method Definition: def toString(): String

Return Type: It returns a string representation of the TreeSet object.

Example #1:

// Scala program of toString()
// 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 toString method
        val result = t1.toString

        // Display output
        print("String representation of the TreeSet object: " + result)

    }
}

Output:

TreeSet(1, 2, 3, 4, 5, 6)
String representation of the TreeSet object: TreeSet(1, 2, 3, 4, 5, 6)

Example #2:

// Scala program of toString()
// 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 toString method
        val result = t1.toString

        // Display output
        print("String representation of the TreeSet object: " + result)

    }
}

Output:

TreeSet(a, e, i, o, u)
String representation of the TreeSet object: TreeSet(a, e, i, o, u)
