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)
