Program/Source Code:

The source code to iterate set 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 iterate set elements
// using the foreach loop

import scala.collection.immutable._

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

    println("Set elements:");
    numbers.foreach((number: Int) => println(number));
  }
}

Output:

Set elements:
10
20
50
40
30

Explanation:

Here, we used an object-oriented approach to create the program. And, 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 set of numbers using the Set collection class. Then we iterate elements of set numbers using the foreach loop and printed them on the console screen.
