The diff() method is used to find the difference between the two TreeSet. It deletes elements that are present in one TreeSet from the other one.
Method Definition: def diff[B >: A](that: collection.Seq[B]): TreeSet[A]
Return Type: It returns a new TreeSet which consists of elements after the difference between the two given TreeSet.
Example #1:
// Scala program of diff() // method // Import TreeSet import scala.collection.mutable. _
// Creating object object GfG
{ // Main method
def main(args : Array[String])
{
// Creating TreeSet
val t 1 = TreeSet( 1 , 2 , 3 , 4 , 5 )
val t 2 = TreeSet( 3 , 4 , 5 )
// Print the TreeSet
println( "TreeSet_1: " + t 1 )
println( "TreeSet_2: " + t 2 )
// Applying diff method
val result = t 1 .diff(t 2 )
// Displays output
print( "(TreeSet_1 - TreeSet_2): " + result)
}
} |
Output:
TreeSet_1: TreeSet(1, 2, 3, 4, 5) TreeSet_2: TreeSet(3, 4, 5) (TreeSet_1 - TreeSet_2): TreeSet(1, 2)
Example #2:
// Scala program of diff() // method // Import TreeSet import scala.collection.mutable. _
// Creating object object GfG
{ // Main method
def main(args : Array[String])
{
// Creating TreeSet
val t 1 = TreeSet( 1 , 2 , 3 , 4 , 5 )
val t 2 = TreeSet( 3 , 4 , 5 , 6 , 7 , 8 )
// Print the TreeSet
println( "TreeSet_1: " + t 1 )
println( "TreeSet_2: " + t 2 )
// Applying diff method
val result = t 2 .diff(t 1 )
// Displays output
print( "(TreeSet_2 - TreeSet_1): " + result)
}

Output:
TreeSet_1: TreeSet(1, 2, 3, 4, 5) TreeSet_2: TreeSet(3, 4, 5, 6, 7, 8) (TreeSet_2 - TreeSet_1): TreeSet(6, 7, 8)
