Java 中的 ArrayBlockingQueue spliterator()方法
原文:https://www . geeksforgeeks . org/arrayblockingqueue-spliterator-method-in-Java/
ArrayBlockingQueue的拆分器()方法在 ArrayBlockingQueue 的元素上返回一个拆分器。返回的迭代器弱一致。在 Java 8 中，拆分器可以与 Streams 一起使用。分割器也可以单独和批量遍历元素。 语法:
public Spliterator spliterator()
返回值:这个方法在 ArrayBlockingQueue 中的元素上返回一个拆分器。 下面的程序说明了 ArrayBlockingQueue 类的 spliterator()方法: 程序 1:
Java 语言(一种计算机语言，尤用于创建网站)
// Java Program Demonstrate spliterator()
// method of ArrayBlockingQueue
import java.util.concurrent.ArrayBlockingQueue;
import java.util.*;
public class GFG {
public static void main(String[] args)
{
// define capacity of ArrayBlockingQueue
int capacityOfQueue = 7;
// create object of ArrayBlockingQueue
ArrayBlockingQueue<Integer> Queue
= new ArrayBlockingQueue<Integer>(capacityOfQueue);
// Add element to ArrayBlockingQueue
Queue.add(22);
Queue.add(34);
Queue.add(45);
Queue.add(67);
// create Spliterator of Queue
// using spliterator() method
Spliterator<Integer> numbers = Queue.spliterator();
// getExactSize of Spliterator
System.out.println("Size of Spliterator : "
+ numbers.estimateSize());
System.out.println("list of Numbers:");
// forEachRemaining method of Spliterator
numbers.forEachRemaining((n) -> System.out.println(n));
}
}
Output:
Size of Spliterator : 4
list of Numbers:
22
34
45
67
程序 2:
Java 语言(一种计算机语言，尤用于创建网站)
// Java Program Demonstrate spliterator()
// method of ArrayBlockingQueue
import java.util.concurrent.ArrayBlockingQueue;
import java.util.*;
public class GFG {
public static void main(String[] args)
{
// define capacity of ArrayBlockingQueue
int capacityOfQueue = 7;
// create object of ArrayBlockingQueue
ArrayBlockingQueue<String> QueueOfStrings
= new ArrayBlockingQueue<String>(capacityOfQueue);
// Add element to ArrayBlockingQueue
QueueOfStrings.add("India");
QueueOfStrings.add("Pakistan");
QueueOfStrings.add("England");
QueueOfStrings.add("China");
QueueOfStrings.add("UAE");
QueueOfStrings.add("Spain");
// create Spliterator of QueueOfStrings
// using spliterator() method
Spliterator<String>
listOfStrings = QueueOfStrings.spliterator();
// getExactSize of Spliterator
System.out.println("Size of Spliterator : "
+ listOfStrings.estimateSize());
System.out.println("list of Country names:");
// forEachRemaining method of Spliterator
listOfStrings.forEachRemaining((str) -> print(str));
}
public static void print(String str)
{
System.out.println("Value = " + str);
}
}
Output:
Size of Spliterator : 6
list of Country names:
Value = India
Value = Pakistan
Value = England
Value = China
Value = UAE
Value = Spain
