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();
}
}
