Scala Set ++() method with example

The ++() method is utilized to add elements of one set to another set.

Method Definition: def ++(elems: A): Set[A]

Return Type: It returns a new set containing elements of both the sets.

Example #1:

// Scala program of ++()
// method

// Creating object
object GfG
{

    // Main method
    def main(args:Array[String])
    {
        // Creating a set
        val s1 = Set(1, 3, 5)

        val s2 = Set(2, 4, 6)

        // Applying ++() method
        val result = s1 ++ s2

        // Display output
        print(result)

    }
}

Output:

Set(5, 1, 6, 2, 3, 4)

Example #2:

// Scala program of ++()
// method

// Creating object
object GfG
{

    // Main method
    def main(args:Array[String])
    {
        // Creating a set
        val s1 = Set(41, 12, 23, 43, 1, 72)

        val s2 = Set(1, 100, 5, 12, 23)

        // Applying ++() method
        val result = s1 ++ s2

        // Display output
        print(result)

    }
}

Output:

Set(5, 1, 41, 12, 72, 43, 23, 100)
