I'm trying to get a string value from external file with this method:

```
File file = new File(name);
    BufferedReader br = new BufferedReader(new FileReader(file));
    String line = br.readLine();
    br.close();

```

And I have some lines that are equal to "null". But if I compare them to null or "null", or even to "", I get FALSE. What am I doing wrong?
