file reader returning null when file is not null content

hello,

any assistance would be largely appreciated.

                        File FileChecker=new File("/Users/Jason/
Desktop/ad_log.txt");

                        if (!FileChecker.exists()){
                            FileChecker.createNewFile();
                        }else{

                        //build existing records.
                            //Existing_Records=
                            getContents(FileChecker);

                                                } //here i check if
the file exists. if it doesn't i make a new one. otherwise i want to
read my old one, using getContents.

//getContents:

static public void getContents(File args) throws Exception{

    String[] TempLine;

        Scanner freader = new Scanner(args);
        //BufferedWriter writer = new BufferedWriter(new
FileWriter(toFile));

        //... Loop as long as there are input lines.
        String line = null;
        while (freader.hasNextLine()) {
            line = freader.nextLine();
            System.out.println(line);

        }

        //... Close reader and writer.
        freader.close(); // Close to unlock.
        // Close to unlock and flush to disk.
    }

for some reason that i cannot figure out this is returning null.
the file is definitely not null and contains very long strings.
the strings contain new line by using:
 System.out.println("what i write to my file");

any help would be largely appreciated!
