97 Things Every Java Prog. Should Know
summary
Practical, specific takeaways: learn IntelliJ shortcuts and integrations—Alt+Enter, live templates, debugger, Git and Gradle support—to stop thinking about menus and focus on design; write unit-test GUTs with sentence-style spec names (JUnit 5 display name support) instead of brittle method-by-method checks; use approval testing (approval. Java) or snapshot tools for complex or legacy outputs; tune garbage collection by understanding mark‑and‑sweep vs copying collectors and object locality; avoid java.util.Date and use java.time; prepare for interviews by mastering high‑level concurrency utilities and immutability.
