Java 中的 IntStream 迭代器()
IntStream 迭代器()返回该流元素的迭代器。这是一个 终端操作 ，也就是说，它可能穿越河流产生结果或副作用。
语法:
PrimitiveIterator.OfInt iterator()
Where, PrimitiveIterator.OfInt is an Iterator
specialized for int values.
返回值: IntStream 迭代器()返回该流的元素迭代器。
例 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:
2
4
6
8
例 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());
}
}
}
Output:
2
3
4
5
6
7
