管道流主要可以进行两个线程之间的通信。
PipedOutputStream 管道输出流
PipedInputStream 管道输入流
【例子1】验证管道流
/**
* 验证管道流
* */
import java.io.*;
/**
* 消息发送类
* */
class Send implements Runnable{
private PipedOutputStream out=null;
public Send() {
out=new PipedOutputStream();
}
public PipedOutputStream getOut(){
return this.out;
}
public void run(){
String message="hello , Rollen";
try{
out.write(message.getBytes());
}catch (Exception e) {
e.printStackTrace();
}try{
out.close();
}catch (Exception e) {
e.printStackTrace();
}
}
}
/**
* 接受消息类
* */
class Recive implements Runnable{
private PipedInputStream input=null;
public Recive(){
this.input=new PipedInputStream();
}
public PipedInputStream getInput(){
return this.input;
}
public void run(){
byte[] b=new byte[1000];
int len=0;
try{
len=this.input.read(b);
}catch (Exception e) {
e.printStackTrace();
}try{
input.close();
}catch (Exception e) {
e.printStackTrace();
}
System.out.println("接受的内容为 "+(new String(b,0,len)));
}
}
/**
* 测试类
* */
class hello{
public static void main(String[] args) throws IOException {
Send send=new Send();
Recive recive=new Recive();
try{
//管道连接
send.getOut().connect(recive.getInput());
}catch (Exception e) {
e.printStackTrace();
}
new Thread(send).start();
new Thread(recive).start();
}
}
【运行结果】：接受的内容为 hello , Rollen
