JavaArrayBlockingQueue详解与使用教程

• ArrayBlockingQueue(int capacity)：创建指定容量、非公平访问的队列。
• ArrayBlockingQueue(int capacity, boolean fair)：可指定是否公平。
• ArrayBlockingQueue(int capacity, boolean fair, Collection c)：用集合初始化队列。

import java.util.concurrent.ArrayBlockingQueue;
import java.util.concurrent.BlockingQueue;

public class ABQExample {
    private static final int QUEUE_SIZE = 5;
    private static BlockingQueue queue = new ArrayBlockingQueue<>(QUEUE_SIZE);

    public static void main(String[] args) {
        Thread producer = new Thread(() -> {
            for (int i = 1; i <= 10; i++) {
                try {
                    String item = "item-" + i;
                    queue.put(item);
                    System.out.println("生产：" + item);
                } catch (InterruptedException e) {
                    Thread.currentThread().interrupt();
                }
            }
        });

        Thread consumer = new Thread(() -> {
            for (int i = 1; i <= 10; i++) {
                try {
                    String item = queue.take();
                    System.out.println("消费：" + item);
                    Thread.sleep(500); // 模拟处理时间
                } catch (InterruptedException e) {
                    Thread.currentThread().interrupt();
                }
            }
        });

        producer.start();
        consumer.start();
    }
}
