同步队列SynchronizedQueue

没有容量，不存储元素，进去一个元素必须等待取出来之后才能再往里面放一个元素
put/take

public class SynchronizedQueue {
    public static void main(String[] args) {
        BlockingQueue<String> synchronizedQueue = new SynchronizedQueue<>();
        new Thread(()->{
            try {
                System.out.println(Thread.currentThread().getName()+"PUT 1");
                synchronizedQueue.put("1");
                System.out.println(Thread.currentThread().getName()+"PUT 2");
                synchronizedQueue.put("2");
                System.out.println(Thread.currentThread().getName()+"PUT 3");
                synchronizedQueue.put("3");
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
        },"t1").start();
        new Thread(()->{

                TimeUnit.SECONDS.sleep(2);
                System.out.println(Thread.currentThread().getName()+"GET 1"+synchronizedQueue.take());
                TimeUnit.SECONDS.sleep(2);
                System.out.println(Thread.currentThread().getName()+"GET 2"+synchronizedQueue.take());
