Scala TreeSet +() method with example

Last Updated : 03 Nov, 2019

In Scala TreeSet class, the +() method is utilized to add an element to the TreeSet unless it is already present.

Method Definition: def +(elem: A): TreeSet[A] Return Type: It returns a new TreeSet with an additional element unless the element is already present.

Example #1:

Scala

// Scala program of +() 
// method 

// Import TreeSet
import scala.collection.mutable._

// Creating object 
object GfG 
{ 

    // Main method 
    def main(args:Array[String]) 
    { 
    
        // Creating TreeSets
        val t1 = TreeSet("a", "e", "i", "o") 
        
        // Print the TreeSets
        println(t1) 
        
        // Applying +() method  
        val result = t1 + ("u")
        
        // Display output 
        print("After adding an element: " + result) 
         
    } 
}

Output:

TreeSet(a, e, i, o)
After adding an element: TreeSet(a, e, i, o, u)

Example #2:

Scala

// Scala program of +() 
// method 

// Import TreeSet
import scala.collection.mutable._

// Creating object 
object GfG 
{ 

    // Main method 
    def main(args:Array[String]) 
    { 
    
        // Creating TreeSets
        val t1 = TreeSet(2, 1, 5, 4, 1) 
        
        // Print the TreeSets
        println(t1) 
        
        // Applying +() method  
        val result = t1 + (3)
        
        // Display output 
        print("After adding an element: " + result) 
         
    } 
}

Output:

TreeSet(1, 2, 4, 5)
After adding an element: TreeSet(1, 2, 3, 4, 5)
