Scala set: Convert a set to a list

Scala Set Exercise-9 with Solution

Write a Scala program to create a set and convert it to a list.

Sample Solution:

Scala Code:

object SetToListExample {
  def main(args: Array[String]): Unit = {
    // Create a set
    val nums = Set(1, 2, 3, 4)

    // Print the set
    println("Set: " + nums)

    // Convert the set to a list
    val list = nums.toList

    // Print the list
    println("List: " + list)
  }
}

Sample Output:

Set: Set(1, 2, 3, 4)
List: List(1, 2, 3, 4)

Explanation:

In the above exercise,

  • In this program, we create a set "nums" containing the elements 1, 2, 3, and 4.
  • To convert the set to a list, we use the toList method.
  • In the program, we convert the set to a list by using the line val list = set.toList.
  • Finally, we print the set and the converted list.
