Scala Iterator max() 方法与示例

max()方法属于抽象迭代器类的具体值成员。它在IterableOnceOps类中定义。它用于找到最大的元素。

Method Definition : def max[B >: A](implicit ord: math.Ordering[B]): A

Where, B is the type over which the ordering is defined and ord is an ordering to be used for comparing elements.

Return Type :It returns the largest element of the collection stated with respect to the ordering ord.

示例 #1：

// Scala program of max()
// method
  
// Creating object
object GfG
{ 
  
    // Main method
    def main(args:Array[String])
    {
      
        // Declaring an iterator
        val iter = Iterator(22, 36, 66, 19, 21)
          
        // Applying max method
        val iter1 = iter.max
          
        // Displays output
        println(iter1)
  
    }
}

输出：

66

因此，返回集合的最大元素。
示例 #2：

// Scala program of max()
// method
  
// Creating object
object GfG
{ 
  
    // Main method
    def main(args:Array[String])
    {
      
        // Declaring an iterator
        val iter = Iterator(2.2, 3.6, 6.6, 9.9, 2.1)
          
        // Applying max method
        val iter1 = iter.max
          
        // Displays output
        println(iter1)
  
    }
}

输出：

9.9
