Here, we will create two sets of integer numbers using the Set collection class. Then we will perform an intersection operation using intersect() method and print the result on the console screen.

Program/Source Code:

The source code to perform intersection operation between two sets is given below. The given program is compiled and executed on the ubuntu 18.04 operating system successfully.

// Scala program to perform intersection operation
// between two sets

import scala.collection.immutable._

object Sample {
  // Main method
  def main(args: Array[String]) {
    var set1 = Set(10, 20, 30, 40, 50);
    var set2 = Set(70, 20, 50, 80, 90);

    var intersection = set1.intersect(set2);

    println(set1);
    println(set2);
    println(intersection);
  }
}

Output:

HashSet(10, 20, 50, 40, 30)
HashSet(20, 70, 80, 50, 90)
HashSet(20, 50)

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 two sets set1 and set2 using Set collection class. Then we performed an intersection operation between two sets using intersect() method and printed the result on the console screen.
