Scala TreeSet &~() method with example

Last Updated : 03 Nov, 2019

In Scala TreeSet class, the &~() method is utilized to return a new TreeSet which contains the difference between two TreeSets.

Method Definition: def &~(that: TreeSet[A]): TreeSet[A] Return Type: It returns a new TreeSet which contains the difference between two TreeSets.

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(2, 1, 3, 1, 4, 5, 6) 
        
        val t2 = TreeSet(2, 4, 6)
        
        // Print the TreeSets
        println(t1) 
        
        println(t2)
        
        // Applying &~() method  
        val result = t1.&~(t2)
        
        // Display output 
        print("TreeSet containing difference of two TreeSets: " + result) 
         
    } 
}

Output:

TreeSet(1, 2, 3, 4, 5, 6)
TreeSet(2, 4, 6)
TreeSet containing difference of two TreeSets: TreeSet(1, 3, 5)

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("g", "e", "e", "k", "s", "f", "o", "r") 
        
        val t2 = TreeSet("g", "e", "e", "k", "s")
        
        // Print the TreeSets
        println(t1) 
        
        println(t2)
        
        // Applying &~() method  
        val result = t1.&~(t2)
        
        // Display output 
        print("TreeSet containing difference of two TreeSets: " + result) 
         
    } 
}

Output:

TreeSet(e, f, g, k, o, r, s)
TreeSet(e, g, k, s)
TreeSet containing difference of two TreeSets: TreeSet(f, o, r)
