BlockingQueue 定义了一个FIFO的队列接口，。试图向已满队列中放入元素会导致放入操作受阻塞；试图从空队列中检索元素将导致

类似阻塞。

ArrayBlockingQueue是此接口的一个实现。

API：http://www.ostools.net/uploads/apidocs/jdk-zh/java/util/concurrent/ArrayBlockingQueue.html

下面是一个例子：两个线程，thread1， thread2，各自维护队列queue1， queue2，初始时queue2不阻塞，之后两个 thread

在自己的queue中加入元素，在对方的queue中take元素，进行十次这样的操作。

import java.util.concurrent.ArrayBlockingQueue;import java.util.concurrent.BlockingQueue;public class ArrayBlockingCommunication {public static void main(String[] args) {final  Business bussiness  = new Business();new Thread(new Runnable() {public void run() {for (int i = 0; i < 10; i++) {bussiness.methodForThread1(i);}}}).start();new Thread(new Runnable() {public void run() {for (int i = 0; i < 10; i++) {bussiness.methodForThread2(i);}}}).start();}static class Business {BlockingQueue <Integer> queue1 = new ArrayBlockingQueue <Integer> (1);BlockingQueue <Integer> queue2 = new ArrayBlockingQueue <Integer> (1);{try {queue2.put(1);} catch (InterruptedException e) {e.printStackTrace();}}public void methodForThread1(int i) {try {queue1.put(1);System.out.println("Thread " + Thread.currentThread().getName() + " is blocking");} catch (InterruptedException e) {e.printStackTrace();}System.out.println("Thread " + Thread.currentThread().getName() + " is running : " + i);try {queue2.take();} catch (InterruptedException e) {e.printStackTrace();}}public void methodForThread2(int i) {try {queue2.put(1);System.out.println("Thread " + Thread.currentThread().getName() + " is blocking");} catch (InterruptedException e) {e.printStackTrace();}System.out.println("Thread " + Thread.currentThread().getName() + " is running : " + i);try {queue1.take();} catch (InterruptedException e) {e.printStackTrace();}}}}
