java - 使用 Java Swing 的管道连接器

<分区>

如何使用 Java Swing 实现管道连接器，例如 Yahoo 管道。或者就此而言，Java Swing 中的任何其他类型的连接。

最佳答案

下面是在 java 中使用 PipedReader 和 PipedWriter 的例子:

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.PipedReader;
import java.io.PipedWriter;
/**

 * To demonstrate the use of piped character streams.
 * Example program for piped character stream in java.

 */

public class PipedReaderExample {

    public static void main(String args[]) throws IOException{
        PipedReader reader = new PipedReader();
        PipedWriter writer = new PipedWriter(reader);
        Thread readerThread = new Thread(new ReaderThread(writer));
        Thread writerThread = new Thread(new WriterThread(reader));
        readerThread.start();
        writerThread.start();
    }

}

class ReaderThread implements Runnable{
    PipedWriter writer;
    public ReaderThread(PipedWriter writer){
        this.writer = writer;
    }

    public void run() {
        InputStreamReader streamReader = new InputStreamReader(System.in);
        BufferedReader bufferedReader = new BufferedReader(streamReader);
        try {
            while (true) {
                //sample implementation reading from console
                //real implementation can be reading from a socket or a file
                //or from server side code
                String line = bufferedReader.readLine();
                writer.write(line);
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

class WriterThread implements Runnable{
    PipedReader reader;
    public WriterThread(PipedReader reader){
        this.reader = reader;
    }

    public void run() {
        while(true){
            try {
                char c;
                while( (c = (char)reader.read()) != -1){
                    //write your business logic here
                    //could be writing into a file
                    //could be processing the date
                    System.out.println(c);
                }

            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    }
}
