Scala Mutable SortedSet init() method

In Scala mutable collections, SortedSet init() method is utilized to find all the elements of the SortedSet except the last one.

Method Definition: def init: SortedSet[A]

Return Type: It returns all the elements of the SortedSet except the last one.

Example #1:

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


// Creating object
object GfG
{

    // Main method
    def main(args:Array[String])
    {
        // Creating a SortedSet
        val s1 = SortedSet(1, 2, 3, 4, 5)

        // Applying init method
        val result = s1.init

        // Display output
        println(result)
    }
}

Output:

TreeSet(1, 2, 3, 4)

Example #2:

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

// Creating object
object GfG
{

    // Main method
    def main(args:Array[String])
    {
        // Creating a SortedSet
        val s1 = SortedSet(16, 22, 3, 41, 51)

        // Applying init method
        val result = s1.init

        // Display output
        println(result)
    }
}

Output:

TreeSet(3, 16, 22, 41)
