Scala Set diff() method with example

Last Updated : 15 Oct, 2019

The diff() method is utilized to compute the difference of a set and an another set.

Method Definition: def diff(that: Set[A]): Set[A]

Return Type: It returns a set which is the difference between two sets.

Example #1:

// Scala program of diff() 
// method 
  
// Creating object  
object GfG  
{  
  
    // Main method  
    def main(args:Array[String])  
    {  
      
        // Creating sets  
        val s1 = Set(1, 2, 3, 4, 5) 
          
        val s2 = Set(1, 2, 3) 
          
        // Applying diff method  
        val s3 = s1.diff(s2)  
          
        // Displays output  
        for(elem <- s3)   
        println(elem)  
      
    }  
}  

Output:

5
4

Example #2:

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

Output:
