本文介绍了一段使用Java PipedStream进行并发读写操作的示例代码，通过创建PipedOutputStream和PipedInputStream并使用线程进行异步读写，实现了数据的高效传输。

public class PipedStream {


	public static void main(String[] args) throws Exception {
		
		PipedOutputStream pos = new PipedOutputStream();
		PipedInputStream pis = new PipedInputStream();
		
                //使此管道输入流连接到管道输出流
		pis.connect(pos);


		WritePipe wp = new WritePipe(pos);
		ReadPipe rp = new ReadPipe(pis);
		
		new Thread(wp).start();
		new Thread(rp).start();		
	}
	
}
//写入管道流
class WritePipe implements Runnable
{
	private PipedOutputStream pos;
	WritePipe(PipedOutputStream pos)
	{
		this.pos = pos;
	}
	@Override
	public void run() {
		
		try {
			pos.write("guan dao liu xie ru".getBytes());
			pos.close();
		} catch (IOException e) {


			e.printStackTrace();
		}
		
	}
}
//从管道流读取
class ReadPipe implements Runnable
{
	private PipedInputStream pis;
	ReadPipe(PipedInputStream pis)
	{
		this.pis = pis;
	}
	@Override
	public void run() {


		byte[] buf = new byte[1024];
		int len = 0;
		try {
			while((len = pis.read(buf))!=-1)
			{
				System.out.println(new String(buf,0,len));
			}
			pis.close();
		} catch (IOException e) {		
			e.printStackTrace();
		}
	}
