In Scala mutable collection, diff() method is utilized to compute the difference of a SortedSet and an another SortedSet.
Method Definition: def diff(that: SortedSet[A]): SortedSet[A] Return Type: It returns a SortedSet which is the difference between two SortedSets.
Example #1: Scala
// Scala program of diff()
// method
import scala.collection.mutable.SortedSet 

// Creating object 
object GfG 
{ 

    // Main method 
    def main(args:Array[String]) 
    { 
    
        // Creating SortedSets 
        val s1 = SortedSet(1, 2, 3, 4, 5)
        
        val s2 = SortedSet(1, 2, 3)
        
        // Applying diff method 
        val s3 = s1.diff(s2) 
        
        // Displays output 
        for(elem <- s3)  
        println(elem) 
    
    } 
} 
Output:
4
5
Example #2: Scala
// Scala program of diff()
// method
import scala.collection.mutable.SortedSet 

// Creating object 
object GfG 
{ 

    // Main method 
    def main(args:Array[String]) 
    { 
    
        // Creating SortedSets 
        val s1 = SortedSet(1, 2, 3, 4, 5)
        
        val s2 = SortedSet(6, 2, 7, 8)
        
        // Applying diff method 
        val s3 = s1.diff(s2) 
        
        // Displays output 
        for(elem <- s3)  
        println(elem) 
    
    } 
} 
Output:
