IntStream iterator() method in Java

The iterator() method of the IntStream class in Java is used to return an iterator for the elements of this stream.

The syntax is as follows

PrimitiveIterator.OfInt iterator()

Here, PrimitiveIterator.OfInt is an Iterator specialized for int values. To work with the IntStream class in Java, import the following package

import java.util.stream.IntStream;

Create an IntStream and add some elements

IntStream intStream = IntStream.of(15, 40, 55, 70, 95, 120);

To return an iterator for the stream elements

PrimitiveIterator.OfInt primIterator = intStream.iterator();

The following is an example to implement IntStream iterator() method in Java

Example

 Live Demo

import java.util.*;
import java.util.stream.IntStream;
public class Demo {
   public static void main(String[] args) {
      IntStream intStream = IntStream.of(15, 40, 55, 70, 95, 120);
      PrimitiveIterator.OfInt primIterator = intStream.iterator();
      while (primIterator.hasNext()) {
         System.out.println(primIterator.nextInt());
      }
   }
}

Output

15
40
55
70
95
120
