Java PipedReader和PipedWriter类示例

PipedReader类和PipedWriter类是管道字符流。管道用于将输出从一个程序(或线程)发送到另一个程序(或线程)的输入。

以下是使用PipedReader和PipedWriter的示例。 在此示例中，一个线程将数据写入管道，另一个线程从该管道读取数据。

文件：PipedReaderWriterExample.java –

package com.yiibai.tutorial.io;  import java.io.IOException; import java.io.PipedReader; import java.io.PipedWriter;  /**  * @author yiibai  */ public class PipedReaderWriterExample {    public static void main(String[] args) throws Exception {       final PipedReader pipedReader = new PipedReader();       final PipedWriter pipedWriter = new PipedWriter();        // Connect pipe       pipedReader.connect(pipedWriter);        // Writing data to pipe       Thread writerThread = new Thread(new Runnable() {          @Override          public void run() {             try {                for (int i = 65; i <= 70; i++) {                   pipedWriter.write((char) i);                   Thread.sleep(500);                }                pipedWriter.close();             } catch (IOException | InterruptedException e) {                e.printStackTrace();             }          }       });        // Reading data from pipe       Thread readerThread = new Thread(new Runnable() {          @Override          public void run() {             try {                int i;                while ((i = pipedReader.read()) != -1) {                   System.out.println((char) i);                   Thread.sleep(1000);                }                pipedReader.close();             } catch (IOException | InterruptedException e) {                e.printStackTrace();             }          }       });        // Start thread       writerThread.start();       readerThread.start();    } }
