Scala Set diff() method with example

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

// 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

// 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:
