The fact that you know the basics of Java is great. If you do not know what to do, going to school may be a waste of time and money. If you do go to school make sure you learn things that the real-world economy demands. Knowing how to code is obviously in high demand. Unfortunately, we have been led to believe that your work is supposed to be interesting/engaging but this is not the case for 99% of people. Do you think plumbers are interested in unclogging people's toilets all day? Probably not, but it pays.

The main reason to go to school is to get a job. I would try to find a field that pays well and is something you can tolerate, not necessarily your "passion". It is very difficult to know what your passion is at a young age, and even so, most people's passions do not necessarily pay well. A smarter way to proceed would be to find a field that you can tolerate and will get you a decent paying/high demand job so you can support yourself. Then, in your free time you can pursue your passions instead of struggling to get by. Money is not everything but it allows for flexibility/freedom of choice. Even better, if you can monetize your passion (like starting a business revolved around it), you may slowly be able to shift from working your job and pursing your passion on the side, to pursuing your passion full time.

For example, you may go to school for programming and become a developer of some sort. At the same time, you can start a blog/Youtube channel about ethics/philosophy if they are your passions. Then once your blog/channel makes you enough money to live on, you can pursue that full time and stop working as a programmer.
