IntStream iterator() in Java

Last Updated : 21 Mar, 2018

IntStream iterator() returns an iterator for the elements of this stream. It is a terminal operation i.e, it may traverse the stream to produce a result or a side-effect.

Syntax :

PrimitiveIterator.OfInt iterator()

Where, PrimitiveIterator.OfInt is an Iterator 
specialized for int values.

Return Value : IntStream iterator() returns the element iterator for this stream.

Example 1 :

// Java code for IntStream iterator() 
import java.util.*; 
import java.util.stream.IntStream; 
  
class GFG { 
  
    // Driver code 
    public static void main(String[] args) 
    { 
        // Creating an IntStream 
        IntStream stream = IntStream.of(2, 4, 6, 8); 
  
        // Using IntStream iterator() to return 
        // an iterator for elements of the stream 
        PrimitiveIterator.OfInt answer = stream.iterator(); 
  
        // Displaying the stream elements 
        while (answer.hasNext()) { 
            System.out.println(answer.nextInt()); 
        } 
    } 
} 

Output:

Example 2 :

// Java code for IntStream iterator() 
import java.util.*; 
import java.util.stream.IntStream; 
  
class GFG { 
  
    // Driver code 
    public static void main(String[] args) 
    { 
        // Creating an IntStream which includes 
        // lower bound element but excludes 
        // upper bound element 
        IntStream stream = IntStream.range(2, 8); 
  
        // Using IntStream iterator() to return 
        // an iterator for elements of the stream 
        PrimitiveIterator.OfInt answer = stream.iterator(); 
  
        // Displaying the stream elements 
        while (answer.hasNext()) { 
            System.out.println(answer.nextInt()); 
        } 
    } 
}
