使用ReentrantLock和Condition进行线程同步，利用不同的Condition可精确指定要唤醒的线程

public class MyContainer<T> {
    private LinkedList<T> list = new LinkedList<>();
    private int count = 0;
    private int max = 10;

    private Lock lock = new ReentrantLock();
    private Condition producer = lock.newCondition();
    private Condition consumer = lock.newCondition();

    public void put(T t) {
        lock.lock();
        try {
            while (list.size() == max) {
                System.out.println("满啦!" + count);
                producer.await();
            }

            list.add(t);
            count++;
            consumer.signalAll();
        } catch (InterruptedException e) {
            e.printStackTrace();
        } finally {
            lock.unlock();
        }
    }

    public T get() {

        lock.lock();
        T t = null;
        try {
            while (list.size() == 0) {
                System.out.println("空啦!" + count);
                consumer.await();
            }
            t = list.removeFirst();
            count--;
            producer.signalAll();

        } catch (InterruptedException e) {
            e.printStackTrace();
        } finally {
            lock.unlock();
        }

        return t;
    }

    public static void main(String[] args) throws InterruptedException {
        MyContainer<String> container = new MyContainer<>();

        for (int i = 0; i < 10; i++) {
            new Thread(() -> {
                for (int j = 0; j < 5; j++) {
                    String s = container.get();
                    System.out.println(Thread.currentThread().getName() + ":" + s);
                }
            }, "C" + i).start();

        }

        TimeUnit.SECONDS.sleep(2);

        for (int i = 0; i < 2; i++) {
            new Thread(() -> {
                for (int j = 0; j < 30; j++) {
                    container.put(Thread.currentThread().getName() + "  " + j);
                }
            }, "P" + i).start();
        }
    }
