一个简单的JAVA线程池(只是用实验)

package myTest_EA;

import java.util.*;

public class ThreadPool extends Thread
...{

    /** *//**
     * @param args
     */
    
    //pool是作业数
    private List pool;
    
    public ThreadPool(List pool)
    ...{
        this.pool = pool ;
    }
    
    public void run()
    ...{
        for(int i = 0; i < 3; i++)
        ...{
            synchronized(pool)
            ...{
                while(pool.isEmpty())
                ...{
                    try
                    ...{
                        System.out.println( " thread name:" + this.getName() + " pool.wait()");
                        pool.wait();
                    }
                    catch(InterruptedException ex)
                    ...{
                        
                    }
                }
                pool.remove(pool.size() - 1);
                System.out.println(" pool.size()" + pool.size() + " thread name:" + this.getName());
                
            }
        }
        
    }
    
    
    
    public final static int THREAD_COUNT = 5;
    
    public static void main(String[] args)
    ...{
        // TODO Auto-generated method stub
        
        Vector pool = new Vector();
        
        ThreadPool[] threadPool = new ThreadPool[THREAD_COUNT];
        
        System.out.println("a");
        System.out.println(threadPool.length);
        for(int i = 0; i < threadPool.length; i++)
        ...{
            threadPool[i] = new ThreadPool(pool);
            threadPool[i].start();
        }
        System.out.println("b");
        for(int i = 0; i < 10; i++)
        ...{
            synchronized(pool)
            ...{
                System.out.println(" " + i + " " );
                pool.add(0,"bbbbbbbbbb");
                /**//*pool.add(1,"ccc");
                pool.add(2,"dd");
                pool.add(3,"e");
                pool.add(4,"ee");*/
                //pool.add(5,"f");
                pool.notifyAll();
                System.out.println("pool.size:" + pool.size() );
                System.out.println("threadPool:" + threadPool.length );
            }
        }
        
        /**//*for(int i = 0; i < threadPool.length; i++)
        {
            threadPool[i].interrupt();
        }*/
        
        
    }
    
    

}

 

当程序中还有线程处于wait()状态时,程序不会自动退出(未完待续,代码会帖上改进后的)
