Java LongStream iterator()用法及代码示例

LongStream iterator()返回此流的元素的迭代器。这是终端操作，即可能会遍历流以产生结果或副作用。

用法:

PrimitiveIterator.OfLong iterator()

Where, PrimitiveIterator.OfLong is an Iterator 
specialized for long values.

返回值：LongStream iterator()返回此流的元素迭代器。

示例1:

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

输出：

示例2:

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