Scala Iterator take() method with example

The take() method belongs to the concrete value member of the class Abstract Iterator. It is utilized to select the first n elements of the stated iterator.

Method Definition: def take(n: Int): Iterator[A]

Where, n is the number of element to take from the given iterator.

Return Type: It returns the first n values from the stated iterator, or the whole iterator, whichever is shorter.

Example #1:

// Scala program of take() 
// method 
  
// Creating object 
object GfG 
{  
  
    // Main method 
    def main(args:Array[String]) 
    { 
      
        // Creating a Iterator  
        val iter = Iterator(2, 3, 5, 7, 8, 9) 
          
        // Applying take method  
        val iter1 = iter.take(4) 
          
        // Applying while loop and 
        // hasNext() method 
        while(iter1.hasNext) 
        { 
          
            // Applying next() method and 
            // displaying output 
            println(iter1.next()) 
        } 
    } 
} 

Output:

Here, first four elements are displayed as we have selected first four elements in the method.
Example #2:

// Scala program of take() 
// method 
  
// Creating object 
object GfG 
{  
  
    // Main method 
    def main(args:Array[String]) 
    { 
      
        // Creating a Iterator  
        val iter = Iterator(2, 3, 5, 7, 8, 9) 
          
        // Applying take method  
        val iter1 = iter.take(7) 
          
        // Applying while loop and 
        // hasNext() method 
        while(iter1.hasNext) 
        { 
          
            // Applying next() method and 
            // displaying output 
            println(iter1.next()) 
        } 
    } 
} 

Output:

Here, the whole iterator is displayed as the number of elements in that is shorter than the number of elements selected by the method. so, the shorter one is displayed.
