Some Rare but Invaluable Java Patterns 🧵 1) Null Object Pattern Avoid null checks by using a no-op object that implements expected behavior. It keeps code clean by avoiding conditionals around method calls (e.g., if (obj != null) everywhere). Use when returning null leads…
2) Parameter Object Pattern Bundle related parameters into a single object. You can pass the parameter object around different layers, ensuring consistency. Use when methods have too many related args.
3) Fluent Interface / Method Chaining Chain method calls for better readability. Communicates intent clearly (especially in builder-like objects). Use in builders or config-style setups.
4) Execute Around Method Pattern Abstract setup/teardown around an operation. Prevents resource leaks by always handling teardown properly. Use for resource management (e.g. opening/closing files/DB).
5. Initialization-on-Demand Holder (a variant of Singleton) Lazy-load a singleton safely without synchronized. Use when you want performant, thread-safe singleton.
