Scala program to get all elements of the set except first element using tail property

Here, we are going to learn how to get all elements of the set except first element using tail property in Scala programming language?
Submitted by Nidhi, on June 25, 2021

Problem Solution:

Here, we will create a set of strings using the Set collection class. Then we will get all elements of the set except the first element using the tail property and print the result on the console screen.

Program/Source Code:

The source code to get all elements of the set except the first element using the tail property is given below. The given program is compiled and executed on the ubuntu 18.04 operating system successfully.

// Scala program to get the all elements of Set except
// first element using "tail" property

import scala.collection.immutable._

object Sample {
  // Main method
  def main(args: Array[String]) {
    // Set of cities.
    val cities = Set("DELHI", "MUMBAI", "AGRA", "GWALIOR")

    println("Elements: \n" + cities.tail);
  }
}

Output:

Elements: 
Set(MUMBAI, AGRA, GWALIOR)

Explanation:

Here, we used an object-oriented approach to create the program. And, we imported Collection classes using below statement,

import scala.collection.immutable._

Here, we also created a singleton object Sample and defined the main() function. The main() function is the entry point for the program.

In the main() function, we created a set of cities. Then we got all the elements of the set except the first element using the tail property and print the result on the console screen.
