Java concurrency programming: blocking queues

Note the way to use the blocking queue itself

The Put method is used to deposit elements to the end of the queue, and if the queues are full, wait;

The Take method is used to fetch elements from the first team, and if the queue is empty, wait;

The Offer method is used to deposit elements to the end of the queue, and if the queues are full, wait for a certain amount of time, and if the time period is reached, false if the insertion is not successful;

The poll method is used to take elements from the first team, and if the queue is empty, it waits for a certain amount of time, and returns null if the time period is reached, otherwise returns the acquired element;
