最简单的方法是将内容读入两个字符串，例如

The simplest way is to read the contents into two strings e.g.

  FileInputStream fin =  new FileInputStream(args[i]);
  BufferedReader myInput = new BufferedReader(new InputStreamReader(fin));
  StringBuilder sb = new StringBuilder();
  while ((thisLine = myInput.readLine()) != null) {  
             sb.append(thisLine);
  }

，执行 .equals（）就这些而言。您是否需要更复杂的差分功能？

, and perform a .equals() on these. Do you require more complex differencing capabilities ?
