Scala Set: Creating sets and finding the union of two sets

Scala Set Exercise-2 with Solution

Write a Scala program to create a set and find the union of two sets.

Sample Solution:

Scala Code:

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

    // Print the set elements
    println("Set1: " + set1)
    println("Set2: " + set2)
    
    // Find the union of the two sets
    val unionSet = set1.union(set2)

    // Print the union set
    println("Union Set: " + unionSet)
  }
}

Sample Output:

Set1: Set(1, 2, 3, 4)
Set2: Set(3, 4, 5, 6)
Union Set: HashSet(5, 1, 6, 2, 3, 4)

Explanation:

In the above exercise,

• We create two sets: set1 and set2. set1 contains the elements 1, 2, 3, and 4, while set2 contains the elements 3, 4, 5, and 6.
• To find the union of the two sets, we use the "union" method provided by the Set class. The union method takes another set as an argument and returns a new set that contains all the distinct elements from both sets.
• Finally, we print the elements of the union set using string concatenation and the println function.
