belongs to collection: Scala List Programs

0

Here, we will create a list of integers using List collection. Then we will print items of the List collection except the head item using the tail property on the console screen.

The List collection is used to store ordered elements. It extends the LinearSeq trait and is used for the immutable linked list.

Program/Source Code:

The source code to print the items of the List collection except the head item is given below. The given program is compiled and executed on the ubuntu 18.04 operating system successfully.

// Scala program to print the items of
// List collection except head item

import scala.collection.immutable._

object Sample {
  // Main method
  def main(args: Array[String]) {
    var intList = List(8, 5, 3, 2, 4);

    println("Items of List collection except head item: \n" + intList.tail);
  }
}

Output:

Items of List collection except head item: 
List(5, 3, 2, 4)

Explanation:

In the above program, we used an object-oriented approach to create the program. Here 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 list intList using List collection. Then we printed the items of the List collection except the head item using the tail property on the console screen.
