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 t 1 = TreeSet( 2 , 1 , 3 , 4 , 5 ) // Print the TreeSet println(t 1 ) // Applying apply() method val result = t 1 .apply( 0 ) // Displays output println( "TreeSet contains '0': " + result) } } |
Output:
TreeSet(1, 2, 3, 4, 5) TreeSet contains '0': false
