Answer 1

Вот пример использования трубопроводных потоков. Это может быть не так красиво, но он должен получить работу в масштабируемой образом:

final String startToken = ",INDEX,PREVIOUS CLOSE,OPEN,HIGH,LOW,CLOSE,GAIN/LOSS"; 
final String endToken = ",ADVANCES,533";  

final PipedWriter pipedWriter = new PipedWriter();  
PipedReader pipedReaderTmp = null; 
try { 
    pipedReaderTmp = new PipedReader(pipedWriter); 
} catch (IOException e) { 
    // do something smart 
} 
final PipedReader pipedReader = pipedReaderTmp; 

// Consumer  
new Thread(new Runnable() {   
    @Override 
    public void run() { 
     try (CSVReader csvReader = new CSVReader(pipedReader)) {    
      while (true) {       
       String[] line = csvReader.readNext(); // blocks until the next line is available 
       if (line == null) break; // end of stream has been reached 
       // 
       // Nonsense output routine follows; replace with your own logic 
       // 
       for (String component : line) { 
        System.out.print(component + '\t'); 
       } 
       System.out.println(); 
      }    
     } catch (IOException e) { 
      // do something smart 
     }   
    } 
}).start(); 

// Producer 
new Thread(new Runnable() {   
    @Override 
    public void run() { 
     try (BufferedReader br = new BufferedReader(new FileReader("filename"))) {       
      String line = null; 

      // consume everything up to and including the start token 
      while ((line = br.readLine()) != null) { 
       if (startToken.equals(line)) break; 
      } 

      // consume everything up to and including the end token 
      while ((line = br.readLine()) != null) { 
       if (endToken.equals(line)) break; 
       pipedWriter.write(line + '\n');    
      } 
      pipedWriter.close();    
     } 
     catch (IOException e) { 
      // do something smart 
     }   
    } 
}).start(); 

Этот код создает два потока. A производитель читает соответствующие части входного файла (нижняя часть вышеприведенного фрагмента) и передает эти данные потребителю (верхний поток), который обрабатывает его, как если бы он поступал непосредственно из файла на диске.
