I want read a text file into an array. How can I do that?

data = new String[lines.size]

I don\'t want to hard code 10 in the array.

you can do something like this:

  BufferedReader reader = new BufferedReader(new FileReader("file.text"));
    int Counter = 1;
    String line;
    while ((line = reader.readLine()) != null) {
        //read the line 
        Scanner scanner = new Scanner(line);
       //now split line using char you want and save it to array
        for (String token : line.split("@")) {
            //add element to array here 
            System.out.println(token);
        }
    }
    reader.close();
