Scala Program: Checking if a set is a subset of another set

Scala Set Exercise-10 with Solution

Write a Scala program to create a set and check if it is a subset of another set.

Sample Solution:

Scala Code:

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

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

    // Check if set2 is a subset of set1
    val isSubset = set2.subsetOf(set1)

    // Print the result
    if (isSubset) {
      println("Set2 is a subset of Set1.")
    } else {
      println("Set2 is not a subset of Set1.")
    }
  }
}

Sample Output:

Set1: Set(1, 2, 3, 4)
Set2: Set(2, 4)
Set2 is a subset of Set1

Explanation:

In the above exercise,

• First, we create two sets set1 and set2 where set1 contains the elements 1, 2, 3, and 4, and set2 contains the elements 2 and 4.
• To check if set2 is a subset of set1, we use the subsetOf method.
• In the program, we check if set2 is a subset of set1 by using the line val isSubset = set2.subsetOf(set1).
• Finally, we print the sets and the subset check result.
