In Scala Stack class
, the top() method is utilized to return the top element of the stack.
Method Definition: def top: A
Return Type: It returns the top element of the stack.
Example #1:
// Scala program of top() // 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 , 3 , 2 , 7 , 6 , 5 )
// Print the stack
println(s 1 )
// Applying top method
val result = s 1 .top
// Display output
print( "Top element of the stack: " + result)
}
} |
Output:
Stack(1, 3, 2, 7, 6, 5) Top element of the stack: 1
Example #2:
// Scala program of top() // 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 , 3 , 2 , 7 , 6 , 1 )
// Print the stack
println(s 1 )
// Applying top method
val result = s 1 .top
// Display output
print( "Top element of the stack: " + result)
}

Output:
Stack(5, 3, 2, 7, 6, 1) Top element of the stack: 5
