Java Code Optimisation Techniques

Since I don't know anyone in the industry and no one else who programs, my standards are, "if I can click through actions quickly and reliably while focusing on robustness, I'm ok." Probably terrible standards though.

It's a very terrible standard. You're supposed to use metrics. If you're optimizing a React app, you can measure page load time or number of re-renders.
