Scala TreeSet apply() method with example
In Scala TreeSet class, the apply() method is utilized to check if some element is present in the TreeSet or not.
Method Definition: def apply(elem: A): Boolean
Return Type: It returns true if the given element is present in the TreeSet or else returns false.
Example #1:
// Scala program of apply() // 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, 3, 4, 5) // Print the TreeSet println(t1) // Applying apply() method val result = t1.apply(3) // Displays output println("TreeSet contains '3': " + result) } } |
Output:
TreeSet(1, 2, 3, 4, 5) TreeSet contains '3': true
Example #2:
// Scala program of apply() // 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, 3, 4, 5) // Print the TreeSet println(t1) // Applying apply() method val result = t1.apply(0) // Displays output println("TreeSet contains '0': " + result) } } |
Output:
TreeSet(1, 2, 3, 4, 5) TreeSet contains '0': false
