Scala - Get the Vector's Last Element (Using last() Method)

Here, we will create an object of Vector collection. Then we will get the last element of the vector using the last() method and print the result on the console screen.

The Vector is an immutable data structure. We can access vector elements randomly. It extends an abstract class AbstractSeq and IndexedSeq trait. We use the Vector collection to store a large number of elements.

Scala code to print the last element of a vector using the last() method

The source code to print the last element of the vector using the last() method is given below. The given program is compiled and executed on the ubuntu 18.04 operating system successfully.

// Scala program to print the last element of vector
// using last() method

import scala.collection.immutable._

object Sample {
  // Main method
  def main(args: Array[String]) {
    var vector = Vector(50, 20, 40, 30, 70);

    println("Last element: " + vector.last);
  }
}

Output

Last element: 70

Explanation

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

import scala.collection.immutable._

And, 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 vector vector using Vector collection. Then we got the last element of a created vector and printed the result on the console screen.
