Java如何使用ArrayBlockingQueue?
ArrayBlockingQueue是的一种实现,该实现java.util.concurrent.BlockingQueue将队列元素内部存储在数组中。在ArrayBlockingQueue当对象被初始化时,由该构造能够存储元件,用于尺寸限定。定义大小后,将无法更改或调整大小。
下面的代码段演示了ArrayBlockingQueue该类。我们初始化队列,以允许其内部数组最多存储64个元素。
package org.nhooo.example.util.concurrent; import java.util.concurrent.ArrayBlockingQueue; import java.util.concurrent.BlockingQueue; public class ArrayBlockingQueueExample { private BlockingQueue<String> sharedQueue = new ArrayBlockingQueue<>(64); public static void main(String[] args) { new ArrayBlockingQueueExample().createProducerConsumer(); } private void createProducerConsumer() { new Thread(new Runnable() { @Override public void run() { while (true) { System.out.println(Thread.currentThread().getName()); try { sharedQueue.put("DATA"); Thread.sleep(500); } catch (InterruptedException e) { e.printStackTrace(); } } } }, "Producer Thread").start(); new Thread(new Runnable() { @Override public void run() { while (true) { System.out.print(Thread.currentThread().getName() + "=> "); try { System.out.println(sharedQueue.take()); Thread.sleep(1000); } catch (InterruptedException e) { e.printStackTrace(); } } } }, "Consumer Thread-1").start(); } }
