Не могу получить текст из txt файла java

 public static String[] getPtrsInData(String filename) throws IOException { 
        File file = new File(filename); 
        BufferedReader br = new BufferedReader(new FileReader(file)); 
        final String result = br.readLine(); 
        br.close(); 
        return result.split(" "); 
    } 

 1 1 1 1 

 Cannot invoke "String.split(String)" because "result" is null
