Scala TreeSet toString() method with example

Last Updated : 11 Nov, 2019

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

// 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

// 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)
