object GfG
{
// Main method
def main(args:Array[String])
{
// Creating stack
val s1 = Stack(1, 2, 3, 4)
// Print the stack
println(s1)
// Applying product method
val result = s1.product
// Display output
print("Product of all the elements of the stack: " + result)
}
}
输出。
Stack(1, 2, 3, 4)
Product of all the elements of the stack: 24
例子#2。
// Scala program of product()
// method
// Import Stack
import scala.collection.mutable._
// Creating object
object GfG
{
// Main method
def main(args:Array[String])
{
// Creating stack
val s1 = Stack(5, 2, 3, 7)
// Print the stack
println(s1)
// Applying product method
val result = s1.product
// Display output
print("Product of all the elements of the stack: " + result)
}
}
输出。
Stack(5, 2, 3, 7)
