Question

I am using the below method to load a string from file to variable.

private static String readFile(String path) throws IOException {
  FileInputStream stream = new FileInputStream(new File(path));
  try {
    FileChannel fc = stream.getChannel();
    MappedByteBuffer bb = fc.map(FileChannel.MapMode.READ_ONLY, 0, fc.size());
    /* Instead of using default, pass in a decoder. */
    return Charset.defaultCharset().decode(bb).toString();
  }
  finally {
    stream.close();
  }
}

The problem is that my variable has escape characters in it. I want my variables to contain:

some string

but instead it looks like:

some string&#xd

how can i improve my method to not allow that?

You can use Reader instead, and BufferedReader in particular to read lines from TXT file:

BufferedReader br = new BufferedReader(new FileReader(path));
String line = br.readLine(); // this strips line termination characters for you

If you want to read the whole file, there are lots of utility classes that provide this functionality (like Google Guava):

String contents = Files.toString(new File(path), charset);
