Scala TreeSet contains() method with example
In Scala TreeSet class, the contains() method is utilized to check if an element is present in the TreeSet of not.
Method Definition: def contains(elem: A): Boolean
Return Type: It returns true if the element is present in the TreeSet or else it returns false.
Example #1:
// Scala program of contains() // method // Import TreeSet import scala.collection.mutable._ // Creating object object GfG { // Main method def main(args:Array[String]) { // Creating TreeSet val t1 = TreeSet(41, 12, 23, 43, 1, 72) // Print the TreeSet println(t1) // Applying contains() method val result = t1.contains(10) // Display output print("TreeSet contains '10': " + result) } } |
Output:
TreeSet(1, 12, 23, 41, 43, 72) TreeSet contains '10': false
Example #2:
// Scala program of contains() // method // Import TreeSet import scala.collection.mutable._ // Creating object object GfG { // Main method def main(args:Array[String]) { // Creating TreeSet val t1 = TreeSet("g", "e", "e", "k", "s") // Print the TreeSet println(t1) // Applying contains() method val result = t1.contains("k") // Display output print("TreeSet contains 'k': " + result) } } |
Output:
TreeSet(e, g, k, s) TreeSet contains 'k': true
