Use BufferedReader to read the input stream. As BufferedReader will read text from a character-input stream, buffering characters so as to provide for the efficient reading of characters, arrays, and lines. InputStream represents an input stream of bytes. reader.readLine() will read the file line by line.

BufferedReader reader = new BufferedReader(new InputStreamReader(in));
StringBuilder out = new StringBuilder();
String line;
while ((line = reader.readLine()) != null) {
    out.append(line);   // add everything to StringBuilder 
    // here you can have your logic of comparison.
    if(line.toString().equals(".")) {
        // do something
    } 

}
