Example #1: Scala // Scala program of addString() // method with a separator // Creating object object GfG { // Main method def main(args:Array[String]) { // Creating a map val m1 = Map("geeks" -> 5, "for" -> 3, "cs" -> 2) // Applying addString method // and a separator val result = m1.addString(new StringBuilder(), "_") // Displays output println(result) } } Output: geeks -> 5_for -> 3_cs -> 2 Example #2: Scala // Scala program of addString() // method with a separator // Creating object object GfG { // Main method def main(args:Array[String]) { // Creating a map val m1 = Map("geeks" -> 5, "for" -> 3, "geeks" -> 2) // Applying addString method // and a separator val result = m1.addString(new StringBuilder(), "_") // Displays output println(result) } } Output: geeks -> 2_for -> 3 So, here the identical keys are removed.
