Scala TreeSet toMap() method with example

Last Updated : 11 Nov, 2019

The toMap() method is utilized 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

// Scala program of toMap() 
// 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 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

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