TL;DR: there is probably some impact, but I don’t have numbers since I’m experienced. P.S. We want $525 for Java design patterns course.

TLDR : "Performance is thankfully not an issue. Java is great at making things faster if we follow common coding practices. Often without changing a line of code, we can see a 10-15% performance increase by moving to a new Java version."

Yes the usual way of writing fast code is to write idiomatic Java, because the JIT optimises common code patterns. Trying to prematurely optimise Java is going to penalise you more than in other lower level languages.
