In Scala Stack class
, the size() method is utilized to return the number of elements present in the stack.
Method Definition: def size: Int
Return Type: It returns the number of elements present in the stack.
Example #1:
// Scala program of size() // 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 )
// Print the stack
println(s 1 )
// Applying size method
val result = s 1 .size
// Display output
print( "Size of the stack: " + result)
}
} |
Output:
Stack(1, 2, 3, 4) Size of the stack: 4
Example #2:
// Scala program of size() // method // Import Stack import scala.collection.mutable. _
// Creating object object GfG
{ // Main method
def main(args : Array[String])
{
// Creating stack
val s 1 = Stack( "a" , "e" , "i" , "o" , "u" )
// Print the stack
println(s 1 )
// Applying size method
val result = s 1 .size
// Display output
print( "Size of the stack: " + result)
}
} |
Output:
Stack(a, e, i, o, u) Size of the stack: 5
