Scala Iterator product() 方法与示例

product()方法属于抽象迭代器类的具体值成员。它用于乘以所述集合的所有元素。

Method Definition: val result = iter.product

Return Type: It returns the result obtained by multiplying all the elements of the stated iterator.

示例 #1：

// Scala program of product()
// method
  
// Creating object
object GfG
{ 
  
    // Main method
    def main(args:Array[String])
    {
      
        // Creating a Iterator 
        val iter = Iterator(1, 2, 3, 4, 5, 6)
          
        // Applying product method 
        val result = iter.product
          
        // Displays output
        println(result)
      
    }
}

输出：

720

示例 #2：

// Scala program of product()
// method
  
// Creating object
object GfG
{ 
  
    // Main method
    def main(args:Array[String])
    {
      
        // Creating a Iterator 
        val iter = Iterator(0, 1)
          
        // Applying product method 
        val result = iter.product
          
        // Displays output
        println(result)
      
    }
}

输出：
