Java多线程12 Condition 例子提升完整版

package Thread;
import java.util.concurrent.locks.*;
class BoundedBuffer{
    final Lock lock = new ReentrantLock();//锁对象
    final Condition notFull = lock.newCondition();//生产者
    final Condition notEmpty = lock.newCondition();//消费者
    final Object[] items = new Object[100];//存储商品的容器
    int putptr,takeptr,count;//生产使用的角标，消费者使用的角标，计数器
    public void put(Object x)throws InterruptedException{//生产者
        lock.lock();
        try{
            while(count == items.length){//判断计数器是否已经到数组长度。满了
                notFull.await();//生产就等待
            }
            items[putptr] = x;//按照角标将商品存储到数组中
            if(++putptr == items.length) putptr = 0;//如果数组存满就将角标归零
            ++count;
            notEmpty.signal();
        }
        finally {
            lock.unlock();
        }
    }
    public Object take()throws InterruptedException{
       lock.lock();
       try{
           while(count== 0)
               notEmpty.await();
           Object x = items[takeptr];
           if(++takeptr ==items.length)takeptr = 0;
           --count;
           notFull.signal();
           return x;
       }
       finally {
           lock.unlock();
       }

    }
}
public class ConditionDemo {
}

只有代码和注释
