基本數(shù)據(jù)類：

public class PCData{
    private long value;
    public void set(long value){
        this.value = value;
    }
    public long get(){
        return value;
    }
}

生產(chǎn)者：

import java.util.List;
import java.util.Random;

public class Producer implements Runnable{
    private List<PCData> queue;
    private long length;

    public Producer(List<PCData> queue, long length) {
            this.queue = queue;

    }
    @Override
    public void run() {

        try {
            while(true) {
                if(Thread.currentThread().isInterrupted())
                    break;
                Random r = new Random();
                long tmp = r.nextInt(100);
                System.out.println(Thread.currentThread().getId() + "生產(chǎn)了" + tmp);
                PCData data = new PCData();
                data.set(tmp);
                if(queue.size() >= length) {
                    queue.notifyAll();
                    queue.wait();
                }else {
                    queue.add(data);
                }
            }
            Thread.sleep(1000);
        }catch(InterruptedException e){
            e.printStackTrace();
        }
    }
}

消費(fèi)者：

package version2;
import java.util.List;

public class Consumer implements Runnable{
    private List<PCData> queue;
    
    @Override
    public void run() {
        // TODO Auto-generated method stub

                synchronized (queue) {
                    if(queue.size() == 0) {
                        queue.wait();
                        queue.notifyAll();
                    }
                    data = queue.remove(0);
                }
                System.out.println(Thread.currentThread().getId() + "消費(fèi)了" + data.get());
            }
            Thread.sleep(1000);
        }catch(InterruptedException e) {
            e.printStackTrace();
