Are you looking for ideas on what type of project to design?

This is not a code factory, you know.

Yeah, it's that I've been working java but I'm just lost and confused, I'm pressed for time so I would really appreciate any kind of help;ideas, guidance, template. I appreciate anything and everything.

I knoww, I'd just rreally appreciate any kind of help, don't mean to offend anyone

The first thing I would do is come up with an idea for a project that you want to put together.
Once you decide that, then you can move on to the next step of how to design and implement it.

One idea might be to build a simple banking application that let's users:

-Create an account
-Make deposits
-Make withdrawals
-Check balances
