Scala Program: Find common elements between two sets

Scala Set Exercise-18 with Solution

Write a Scala program to create a set and find the common elements between two sets.

Sample Solution:

Scala Code:

object CommonElementsSetExample {
  def main(args: Array[String]): Unit = {
    // Create two sets
    val set1 = Set(1, 2, 3, 4, 5)
    val set2 = Set(4, 5, 6, 7, 8)

    // Print the sets
    println("Set1: " + set1)
    println("Set2: " + set2)

    // Find the common elements between the two sets
    val commonElements = set1.intersect(set2)

    // Print the common elements
    println("Common elements: " + commonElements)
  }
}

Sample Output:

Set1: HashSet(5, 1, 2, 3, 4)
Set2: HashSet(5, 6, 7, 8, 4)
Common elements: HashSet(5, 4)

Explanation:

In the above exercise,

• First, we create two sets set1 and set2 with some elements.
• To find the common elements between the two sets, we use the intersect method. This returns a new set containing the elements common to both sets.
• In the program, we find the common elements between set1 and set2 by using the line val commonElements = set1.intersect(set2).
• Finally, we print the sets and the common elements.
