使用Java Swing的管道連接器

Question

如何使用Java Swing實現管道連接器，如Yahoo管道。 或者Java Swing中的任何其他類型的接線。

Answer 1

這裏是在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; 
/** 
* @date 1st May, 2011 
* @author sanju.org 
* 
* 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(); 
      } 
     } 
    } 
} 

至於使用雅虎與PipedReader/Writer類我想你會閱讀他們的API連接到URL等

這裏是一個有關PipedReader和PipedWriter（混合教程和信息），這可能是幫助其他鏈接的列表：

• Java IO: Pipes
• Java IO: PipedReader
• PipedReader PipedWriter example（JavaCodeGeeks〔實施例）
• PipedReader and PipedWriter and thread（Java2s例如）

至於事物的迴轉側，以顯示從管道接收到的數據就需要使用一個TextComponent像其中的一個：

• How to Use Editor Panes and Text Panes

各

有setText(...)這將允許您設置的內容
