Java - multiple input files
<p>How does one read multiple input files in Java? I need to read multiple inputs (several text documents) and create a Term Document Matrix.<br>
I can read one file like this: </p>

<pre><code>  File file = new File("a.txt"); 
  int ch;
  StringBuffer strContent = new StringBuffer("");
  FileInputStream stream = null;  
  try
   {
     stream = new FileInputStream(file);   
     while( (ch = stream.read()) != -1)
        strContent.append((char)ch); 
      stream.close();   
   }
</code></pre>

<p>Is there any library to read multiple input files? Or I just need to loop and read all files? All files are <code>txt.</code> </p>
