Scala Queue map() method with example
The map() method is utilized to build a new queue by applying a function to all elements of this queue.
Method Definition: def map[B](f: (A) => B): Queue[B]
Return Type: It returns a new queue containing all the elements after applying the given function.
Example #1:
// Scala program of map() // method // Import Queue import scala.collection.mutable. _ // Creating object object GfG { // Main method def main(args : Array[String]) { // Creating a queue val q 1 = Queue( 1 , 3 , 2 , 7 , 6 , 5 ) // Print the queue println(q 1 ) // Applying map method val result = q 1 .map(x => x*x) // Display output print( "New queue after squaring all elements: " + result) } } |
Output:
Queue(1, 3, 2, 7, 6, 5) New queue after squaring all elements: Queue(1, 9, 4, 49, 36, 25)
Example #2:
// Scala program of map() // method // Import Queue import scala.collection.mutable. _ // Creating object object GfG { // Main method def main(args : Array[String]) { // Creating a queue val q 1 = Queue( 1 , 3 , 2 , 7 , 6 , 5 ) // Print the queue println(q 1 ) // Applying map method val result = q 1 .map(x => x/ 2 ) // Display output print( "New queue after dividing all elements by 2: " + result) } } |
Output:
Queue(1, 3, 2, 7, 6, 5) New queue after dividing all elements by 2: Queue(0, 1, 1, 3, 3, 2)
