Scala Iterator max() method with example

Last Updated : 30 Jun, 2019

The max() method belongs to the concrete value members of the class Abstract Iterator. It is defined in the classes IterableOnceOps. It is utilized to find the largest element.

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.

Example #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) 
  
    } 
} 

Output:

Therefore, the largest element of the collection stated is returned.
Example #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) 
  
    } 
}
