Scala - Printing Vector Elements (Using foreach Loop)

Here, we will create an object of Vector collection. Then we will print the elements of the vector with or without using the foreach loop 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 vector elements using the foreach loop

The source code to print the vector elements using the foreach loop is given below. The given program is compiled and executed on the ubuntu 18.04 operating system successfully.

// Scala program to print the vector elements 
// using foreach loop

import scala.collection.immutable._

object Sample {
  // Main method
  def main(args: Array[String]) {
    var vector = Vector(10, 20, 30, 40, 50);

    println(vector);

    println("Vector elements using 'foreach' loop:");
    vector.foreach((item: Int) => print(item + " "));
    println();
  }
}

Output

Vector(10, 20, 30, 40, 50)
Vector elements using 'foreach' loop:
10 20 30 40 50

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 printed the elements of vector with or without using the foreach loop.
