Java IntStream iterator()

IntStream iterator() 返回这个流的元素的一个迭代器。它是一个 终端操作 ，即它可以遍历流，以产生一个结果或一个副作用。

语法

**PrimitiveIterator.OfInt iterator()**

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

返回值： IntStream iterator()返回该流的元素迭代器。

例子 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());
        }
    }
}

输出。
