    public static void main(String[] args) {

        // Long.parseLong() - returns long
        System.out.println(Long.parseLong("123")); // 123
        System.out.println(Long.parseLong("+123")); // 123
        System.out.println(Long.parseLong("-123")); // -123

        // Long.valueOf() - returns Long
        System.out.println(Long.valueOf("123")); // 123
        System.out.println(Long.valueOf("+123")); // 123
        System.out.println(Long.valueOf("-123")); // -123
