Read input file java


Use some data structure to hold your data.
If you know size of your file, array is the best option. Or you can use LinkedList, ArrayList
For Example

LinkedList<String> list = new
LinkedList<>();
File file = new File("data.txt");

    try {

        Scanner scanner = new Scanner(file);

        while (scanner.hasNextLine()) {
            String line = scanner.nextLine();
            list.add(line);
        }
        scanner.close();
    } catch (FileNotFoundException e) {
        e.printStackTrace();
    }

How to verify form input using HTML5 input verification
These patterns aren't necessarily simple, but here's what I think works best in every situation. Keep in mind that (quite recently) Internationalized Domain Names (IDNs) are available too. With that, an un-testable amount of characters are allowed in URLs (there still exist lots of characters that aren't allowed in domain names, but the list of allowed characters is so big, and will change so ofte
