Scala - Adding an Element to Vector

Here, we will create an object of Vector collection. Then we will add an item into the Vector collection using the ":+" operator. After that, we will print the created vector 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 add an item into Vector collection

The source code to add an item into the Vector collection is given below. The given program is compiled and executed on the ubuntu 18.04 operating system successfully.

// Scala program to add an item
// into Vector collection

import scala.collection.immutable._

object Sample {
  // Main method
  def main(args: Array[String]) {
    var vector: Vector[String] = Vector("ABC", "LMN", "PQR", "XYZ");

    var vectorNew = vector :+ "TUV";
    println(vectorNew);
  }
}

Output

Vector(ABC, LMN, PQR, XYZ, TUV)

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 added an item "TUV" in vector and assigned the result to vectorNew. After that, we printed the elements of vectorNew on the console screen.
