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 s 1 = Set( 1 , 2 , 3 , 4 , 5 )
val s 2 = Set( 1 , 2 , 3 )
// Applying diff method
val s 3 = s 1 .diff(s 2 )
// Displays output
for (elem < - s 3 )
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 s 1 = Set( 1 , 2 , 3 , 4 , 5 )
val s 2 = Set( 6 , 2 , 7 , 8 )
// Applying diff method
val s 3 = s 1 .diff(s 2 )
// Displays output
for (elem < - s 3 )
println(elem)
}
} |
Output:
5 1 3 4
