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

// 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

// 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)
