Scala Stack toMap() method with example
In Scala Stack class
, the toMap() method is utilized to return a map consisting of all the elements of the stack.
Method Definition: def toMap[T, U]: Map[T, U]
Return Type: It returns a map consisting of all the elements of the stack.
Example #1:
// Scala program of toMap() // method // Import Stack import scala.collection.mutable. _ // Creating object object GfG { // Main method def main(args : Array[String]) { // Creating stack val s 1 = Stack(( 1 , 2 ), ( 3 , 4 ), ( 5 , 6 )) // Print the stack println(s 1 ) // Applying toMap method val result = s 1 .toMap // Display output print( "Elements in the map: " + result) } } |
Output:
Stack((1, 2), (3, 4), (5, 6)) Elements in the map: Map(1 -> 2, 3 -> 4, 5 -> 6)
Example #2:
// Scala program of toMap() // method // Import Stack import scala.collection.mutable. _ // Creating object object GfG { // Main method def main(args : Array[String]) { // Creating stack val s 1 = Stack(( 5 , 2 ), ( 13 , 7 ), ( 1 , 3 )) // Print the stack println(s 1 ) // Applying toMap method val result = s 1 .toMap // Display output print( "Elements in the map: " + result) } } |
Output:
Stack((5, 2), (13, 7), (1, 3)) Elements in the map: Map(5 -> 2, 13 -> 7, 1 -> 3)
