本文通过一个多线程示例展示了Java中管道流(PipedInputStream和PipedOutputStream)的基本使用方法，实现了发送者(Sender)和接收者(Receiver)之间的简单通信。

管道流多用于多任务之间的通信

一、Sender

package test.pipstream;

import java.io.*;

public class Sender extends Thread
{
    PipedOutputStream out = new PipedOutputStream();

    public PipedOutputStream getOut()
    {
        return out;
    }

    public void run()
    {
        String str = "Hello,receiver   !   I`m   sender/n";
        
        try
        {
            out.write(str.getBytes());
            out.close();
        } catch (Exception e)
        {
            e.printStackTrace();
        }
    }
}

二、Receiver

package test.pipstream;

import java.io.*;

public class Receiver extends Thread
{
    PipedInputStream in = new PipedInputStream();

    public PipedInputStream getIn()
    {
        return in;
    }

    public void run()
    {
        byte[] buf = new byte[1024];
        try
        {
            int len = in.read(buf);
            System.out.println("the   following   is   from   sender:/n" + new String(buf, 0, len));
            in.close();
        } catch (Exception e)
        {
            e.printStackTrace();
        }
    }
}

三、多线程实现， main

package test.pipstream;

import java.io.*;

class TestPiped
{
    public static void main(String[] args)
    {
        Sender s = new Sender();
        Receiver r = new Receiver();
        
        PipedOutputStream out = s.getOut();
        PipedInputStream in = r.getIn();
        
        try
        {
            in.connect(out);
            s.start();
            r.start();
        } catch (Exception e)
        {
            e.printStackTrace();
        }
    }
}
