Last Updated : 26 Mar, 2020

In Scala mutable collections, SortedSet head() method is utilized to display the first element of the SortedSet.

Method Definition: def head: A Return Type: It returns the first element of the SortedSet.

Example #1:

Scala

// Scala program of head() 
// method 
import scala.collection.mutable.SortedSet 

// Creating object 
object GfG 
{ 

    // Main method 
    def main(args:Array[String]) 
    { 
        // Creating a SortedSet 
        val s1 = SortedSet(12, 15, 14, 13) 
        
        // Applying head method 
        val result = s1.head
        
        // Display output
        println(result)
    } 
}

Output:

Example #2:

Scala

// Scala program of head() 
// method 
import scala.collection.mutable.SortedSet 

// Creating object 
object GfG 
{ 

    // Main method 
    def main(args:Array[String]) 
    { 
        // Creating a SortedSet 
        val s1 = SortedSet(6, 7, 5, 4, 1) 
        
        // Applying head method 
        val result = s1.head
        
        // Display output
        println(result)
    }
