Scala Queue diff() method with example Last Updated : 23 Oct, 2019 Summarize Comments Improve Suggest changes Share Like Article Like Report The diff() method is used to find the difference between the two queues. It deletes elements that are present in one queue from the other one. Method Definition: def diff[B >: A](that: collection.Seq[B]): Queue[A] Return Type: It returns a new queue which consists of elements after the difference between the two queues. Example #1: Scala // Scala program of diff() // method // Import Queue import scala.collection.mutable._ // Creating object object GfG { // Main method def main(args:Array[String]) { // Creating queues val q1 = Queue(1, 2, 3, 4, 5) val q2 = Queue(3, 4, 5) // Print the queue println("Queue_1: " + q1) println("Queue_2: " + q2) // Applying diff method val result = q1.diff(q2) // Displays output print("(Queue_1 - Queue_2): " + result) } } Output: Queue_1: Queue(1, 2, 3, 4, 5) Queue_2: Queue(3, 4, 5) (Queue_1 - Queue_2): Queue(1, 2) Example #2: Scala // Scala program of diff() // method // Import Queue import scala.collection.mutable._ // Creating object object GfG { // Main method def main(args:Array[String]) { // Creating queues val q1 = Queue(1, 2, 3, 4, 5) val q2 = Queue(3, 4, 5, 6, 7, 8) // Print the queue println("Queue_1: " + q1) println("Queue_2: " + q2) // Applying diff method val result = q2.diff(q1) // Displays output print("(Queue_2 - Queue_1): " + result) } } Output: Queue_1: Queue(1, 2, 3, 4, 5) Queue_2: Queue(3, 4, 5, 6, 7, 8) (Queue_2 - Queue_1): Queue(6, 7, 8) Comment More infoAdvertise with us Next Article Scala Queue find() method with example R rupesh_rao Follow Improve Article Tags : Scala Scala Scala-Method scala-collection Similar Reads Scala Queue distinct() method with example The distinct() method is utilized to remove the duplicate elements from the given queue.
