File manipulation, like any kind of computer programming, can be programmed in a high-level or low-level way. High-level is easier and reflects some assumptions and opinions. Low-level gives you more control. With Java, you can choose which way you want to go, and the easier route is only as "difficult" as choosing a high-level framework.
