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:
