Output:
TreeSet(a, e, i, o, u) After removing an element: TreeSet(a, e, i, o)
Example #2:
// Scala program of -() // method // Import TreeSet import scala.collection.mutable._ // 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)
