生产者与消费者模式代码简单实现

主要涉及知识点为线程同步问题

店员类：

class Clerk{
     private int productCount = 0;
     public synchronized void produceProduct(){
            if(productCount < 20){
                  productCount++;
                  System.out.println(Thread.currentThread().getName + ":"+productCount)
                  notify();
            }else{
                 try{
                     wait();
                 }catch(InterrupedExceotion e){
                     e.printStackTrace();
                 } 
            }
      }
      
      
      public synchronized void consumeProduct(){
            if(productCount > 0){
                  productCount--;
                  System.out.println(Thread.currentThread().getName + ":"+productCount)
                  notify();
            } else{
                  try{
                      wait();
                  }catch(InterrupedExceotion e){
                      e.printStackTrace();
                  }
            }
     }
 }

生产者类

  class Producer extend Thread{
        private Clerk clerk;
        
        public Producer(Clerk clerk){
               this.clerk = clerk;
        }
        piblic void run(){
               while(true){
                     clerk.produceProduct();
               }
        }
 }

消费者类

class Consumer extend Thread{
      private Clerk clerk;
      
      public Consumer(Clerk clerk){
             this.clerk = clerk;
      }
      public void run(){
             while(true){
                   clerk.consumeProduct();
             }
      }
}

测试类

public class ProductTest{
       public static void main(String[] args){
              Clerk clerk = new Clerk();
              Producer p1 = new Producer(clerk);
              p1.setName("生产者");
              Consumer c1 = new Consumer(clerk);
              c1.setName("消费者");
              p1.start();
              c1.start();
       }
}
