Example #1:
// Scala program of mkString() // method // Import TreeSet import scala.collection.mutable. _ // Creating object object GfG { // Main method def main(args : Array[String]) { // Creating TreeSet val t 1 = TreeSet( 3 , 1 , 5 , 2 , 4 ) // Print the TreeSet println(t 1 ) // Applying mkString method val result = t 1 .mkString( ", " ) // Displays output print( "TreeSet: " + result) } } |
Output:
TreeSet(1, 2, 3, 4, 5) TreeSet: 1, 2, 3, 4, 5
Example #2:
// Scala program of mkString() // method // Import TreeSet import scala.collection.mutable. _ // Creating object object GfG { // Main method def main(args : Array[String]) { // Creating TreeSet val t 1 = TreeSet( "u" , "a" , "i" , "o" , "e" ) // Print the TreeSet println(t 1 ) // Applying mkString method val result = t 1 .mkString( ", " ) // Displays output print( "TreeSet: " + result) } } |
Output:
TreeSet(a, e, i, o, u) TreeSet: a, e, i, o, u
