Scala Stack product() 方法与示例

在 Scala Stack class中， product()方法用于返回栈中所有元素的乘积。

Method Definition: def product: A

Return Type: It returns the product of all the elements of the stack.

示例 #1：

// 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(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

示例 #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)
Product of all the elements of the stack: 210
