Java coding hacks developers should know 🧵 1) Use Map.ofEntries() for creating multi-pair immutable maps Why: Shorter, immutable, safer and avoids accidental mutation.
2) Use Optional. map().orElse() instead of manual null handling Why: Eliminates null checks, reads better, and chains smoothly with other logic.
3) Use Enum.valueOf() + name() for safe enum conversion Why: Cleaner, and lets you easily serialize/deserialize enums in APIs, DB, or files.
4) Use Comparator.comparing().thenComparing() instead of custom logic Why: Clear, readable, no error-prone conditional comparisons
5) Use Optional.ifPresentOrElse() instead of if-else with isPresent() Why: Cleaner and more expressive - no more manual get() calls or if-else clutter.
