Scala TreeSet tail() method with example

The tail() method is utilized to return a new TreeSet that consists of all the elements except the first one.

Method Definition: def tail: TreeSet[A]

Return Type: It returns a new TreeSet that consists of all the elements except the first one.

Example #1:

// Scala program of tail()
// method

// Import TreeSet
import scala.collection.mutable._

// Creating object
object GfG
{

    // Main method
    def main(args:Array[String])
    {

        // Creating TreeSet
        val t1 = TreeSet(1, 3, 2, 7, 6, 5)

        // Print the TreeSet
        println(t1)

        // Applying tail() method
        val result = t1.tail

        // Displays output
        println("Elements of the TreeSet except the first one: " + result)

    }
}

Output:

TreeSet(1, 2, 3, 5, 6, 7)
Elements of the TreeSet except the first one: TreeSet(2, 3, 5, 6, 7)

Example #2:

// Scala program of tail()
// method

// Import TreeSet
import scala.collection.mutable._

// Creating object
object GfG
{

    // Main method
    def main(args:Array[String])
    {

        // Creating TreeSet
        val t1 = TreeSet("a", "e", "i", "o", "u")

        // Print the TreeSet
        println(t1)

        // Applying tail() method
        val result = t1.tail

        // Displays output
        println("Elements of the TreeSet except the first one: " + result)

    }
}

Output:

TreeSet(a, e, i, o, u)
Elements of the TreeSet except the first one: TreeSet(e, i, o, u)
