Where can I get real tasks and ideas for Java?

Question

Java

Good afternoon, I'm tired of the php + js bundle, and in general the web as a whole, because whatever one may say, freelancing, what in the office, the tasks are mainly to fix the layout, etc., in short, I'm a layout designer, not a programmer, and I I'm a bit ashamed, I want real tasks.
And so I decided that it was time to step into the world of Java, a couple of years ago I wrote an android application on it, but somehow I didn’t really like it at all, alas :(
Where can I get interesting and real tasks for Java, in any area other than the web, I don’t really want to solve classic mat problems that are solved in any PL + - a couple of lines in the same
way
. or a resource with interesting tasks)

Answer 2

Java is a general purpose language, with a very long history, rather conservative, with an enterprise leaning. I think that no matter how small a task you take on, the world of modern programming languages ​​is likely to offer something more specialized for it and, accordingly, more convenient.
If you are interested in Java, try to look at the new features of the language and how to use them. Here, for example, here: https://jcp.org/en/jsr/stage?listBy=final
