Java is rarely used for sexy stuff like front-ends or (increasingly) apps. Java is, however, used for services. Bank logins, search engines (Google originally used it), insurance systems. C#, C++ and Rust are in the same area. But Java, for the most case, has been around longer. A LOT of companies used it and can't easily switch their codebase to something newer and shinier. And now Java improves with every release they have fewer reasons to move.
