TreeSet class, the -() method is utilized to remove an element from the given TreeSet.
Method Definition: def -(elem: A): TreeSet[A] Return Type: It returns a new TreeSet with an element removed from the given TreeSet.Example #1:
// Scala program of -()
// method
// Import TreeSet
import scala.collection.immutable._
// Creating object
object GfG
{
// Main method
def main(args:Array[String])
{
// Creating TreeSet
val t1 = TreeSet("a", "e", "i", "o", "u")
// Print the TreeSet
println(t1)
// Applying -() method
val result = t1 - ("u")
// Display output
print("After removing an element: " + result)
}
}
Output:
Example #2:
TreeSet(a, e, i, o, u) After removing an element: TreeSet(a, e, i, o)
// Scala program of -()
// method
// Import TreeSet
import scala.collection.immutable._
// Creating object
object GfG
{
// Main method
def main(args:Array[String])
{
// Creating TreeSet
val t1 = TreeSet(2, 1, 5, 4, 1, 3)
// Print the TreeSet
println(t1)
// Applying -() method
val result = t1 - (1)
// Display output
print("After removing an element: " + result)
}
}
Output:
TreeSet(1, 2, 3, 4, 5) After removing an element: TreeSet(2, 3, 4, 5)
