本文通过一个Java示例程序介绍了如何使用PipedInputStream和PipedOutputStream进行线程间通信。具体展示了如何创建两个线程，一个用于写入数据（如一周的日期名称），另一个用于读取这些数据。

import java.io.BufferedReader; import java.io.IOException; import java.io.InputStreamReader; import java.io.PipedInputStream; import java.io.PipedOutputStream; import java.io.PrintStream; class myWriter extends Thread { private PipedOutputStream outStream;//将数据输出 private String messages[]={"Monday","Tuesday","Wednsday","Thursday","Friday","Saturday","Sunday"}; public myWriter(PipedOutputStream o) { outStream=o; } public void run() { PrintStream p=new PrintStream(outStream); for(int i=0;i<messages.length;i++) { p.println(messages[i]); p.flush(); System.out.println("Write:" +messages[i]); } p.close(); p=null; } } class myReader extends Thread { private PipedInputStream inStream;//从中读取数据 public myReader(PipedInputStream i) { inStream=i; } public void run() { String line; boolean reading=true; BufferedReader d=new BufferedReader(new InputStreamReader(inStream)); while(reading&&d!=null){ try{ line=d.readLine(); if(line!=null) System.out.println("Read:" +line); else reading=false; }catch(IOException e){} } try{ Thread.currentThread().sleep(4000); }catch(InterruptedException e){} } } class Pipedthread { public static void main(String args[]) { Pipedthread thisPipe=new Pipedthread(); thisPipe.process(); } public void process() { PipedInputStream inStream; PipedOutputStream outStream; try{ outStream=new PipedOutputStream(); inStream=new PipedInputStream(outStream); new myWriter(outStream).start(); new myReader(inStream).start(); }catch(IOException e) {} } }
