Scala program to print the vector elements using the foreach loop

Program/Source Code:

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.
