Here, we will create a list of integers using List collection. Then we will access items of the List using index and print them 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 access list items using the index is given below. The given program is compiled and executed on the ubuntu 18.04 operating system successfully.

// Scala program to access list items using index

import scala.collection.immutable._

object Sample {
  // Main method
  def main(args: Array[String]) {
    var intList = List(1, 2, 3, 4, 5);
    var cnt: Int = 0;

    println("List items:");
    while (cnt < 5) {
      printf("%d ", intList(cnt));
      cnt = cnt + 1;
    }
    println();
  }
}

Output:

List items:
1 2 3 4 5

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 accessed elements of the list based on an index. After that, we printed the list items on the console screen.
