采用Java 多线程技术，设计实现一个符合生产者和消费者问题的程序。对一个对象（枪膛）进行操作，其最大容量是12颗子弹。生产者线程是一个压入线程，它不断向枪膛中压入子弹；消费者线程是一个射出线程，它不断从枪膛中射出子弹-Use of Java multi-threading technology, designed to achieve a consistent producer and consumer issues programs. Pairs of an object (the chamber) to operate with a maximum capacity of 12 bullets. The producer thread is pressed into a thread, it continues to press into the bullet in the chamber　consumer thread is a thread injection, it continues to bullets fired from the barrel of
