Read the original file for full details. - -IMPORTANT: We do TDD so all code must include targeted unit tests. -IMPORTANT: Never disable tests written for logic that we are yet to write we do Red-Green-Refactor coding. - -## Core Principles - -* Use Records for all data structures. Use sealed interfaces for protocols. -* Prefer static methods with Records as parameters -* Default to package-private scope -* Package-by-feature, not package-by-layer -* Create fewer, cohesive, wide packages (functionality modules or records as protocols) -* Use public only when cross-package access is required -* Use JEP 467 Markdown documentation examples: `/// good markdown` not legacy `/** bad html */` -* Apply Data-Oriented Programming principles and avoid OOP -* Use Stream operations instead of traditional loops. Never use `for(;;)` with mutable loop variables use - `Arrays.setAll` -* Prefer exhaustive destructuring switch expressions over if-else statements -* Use destructuring switch expressions that operate on Records and sealed interfaces -* Use anonymous variables in record destructuring and switch expressions -* Use `final var` for local variables, parameters, and destructured fields -* Apply JEP 371 "Local Classes and Interfaces" for cohesive files with narrow APIs - -## Data-Oriented Programming - -* Separate data (immutable Records) from behavior (never utility classes always static methods) -* Use immutable generic data structures (maps, lists, sets) and take defense copies in constructors -* Write pure functions that don't modify state -* Leverage Java 21+ features: - * Records for immutable data - * Pattern matching for structural decomposition - * Sealed classes for exhaustive switches - * Virtual threads for concurrent processing - -## Package Structure - -* Use default (package-private) access as the standard. Do not use 'private' or 'public' by default. -* Limit public to genuine cross-package APIs -* Prefer package-private static methods. Do not use 'private' or 'public' by default. -* Limit private to security-related code -* Avoid anti-patterns: boilerplate OOP, excessive layering, dependency injection overuse - -## Constants and Magic Numbers - -* **NEVER use magic numbers** - always use enum constants -* **NEVER write large if-else-if statements over known types** - will not be exhaustive and creates bugs when new types are added. Use exhaustive switch statements over bounded sets such as enum values or sealed interface permits - -## Functional Style - -* Combine Records + static methods for functional programming -* Emphasize immutability and explicit state transformations -* Reduce package count to improve testability -* Implement Algebraic Data Types pattern with Function Modules -* Modern Stream Programming -* Use Stream API instead of traditional loops -* Write declarative rather than imperative code -* Chain operations without intermediate variables -* Support immutability throughout processing -* Example: `IntStream.range(0, 100).filter(i -> i % 2 == 0).sum()` instead of counting loops -* Always use final variables in functional style. -* Prefer `final var` with self documenting names over `int i` or `String s` but its not possible to do that on a `final` variable that is not yet initialized so its a weak preference not a strong one. -* Avoid just adding new functionality to the top of a method to make an early return. It is fine to have a simple guard statement. Yet general you should pattern match over the input to do different things with the same method. Adding special case logic is a code smell that should be avoided. - -## Documentation using JEP 467 Markdown documentation - -IMPORTANT: You must not write JavaDoc comments that start with `/**` and end with `*/` -IMPORTANT: You must "JEP 467: Markdown Documentation Comments" that start all lines with `///` - -Here is an example of the correct format for documentation comments: - -```java -/// Returns a hash code value for the object. This method is -/// supported for the benefit of hash tables such as those provided by -/// [java.util.HashMap]. -/// -/// The general contract of `hashCode` is: -/// -/// - Whenever it is invoked on the same object more than once during -/// an execution of a Java application, the `hashCode` method -/// - If two objects are equal according to the -/// [equals][#equals(Object)] method, then calling the -/// - It is _not_ required that if two objects are unequal -/// according to the [equals][#equals(Object)] method, then -/// -/// @return a hash code value for this object. -/// @see java.lang.Object#equals(java.lang.Object) -``` - -## Logging - -- Use Java's built-in logging: `java.util.logging.Logger` -- Log levels: Use appropriate levels (FINE, FINER, INFO, WARNING, SEVERE) - - **FINE**: Production-level debugging, default for most debug output - - **FINER**: Verbose debugging, detailed internal flow, class resolution details - - **INFO**: Important runtime information -- LOGGER is a static field: `static final Logger LOGGER = Logger.getLogger(ClassName.class.getName());` where use the primary interface or the package as the logger name with the logger package-private and shared across the classes when the package is small enough. -- Use lambda logging for performance: `LOGGER.fine(() -> "message " + variable);` - -# Compile, Test, Debug Loop - -- **Check Compiles**: Focusing on the correct mvn module run without verbose logging and do not grep the output to see compile errors: - ```bash - $(command -v mvnd || command -v mvn || command -v ./mvnw) -pl json-java21-api-tracker -Djava.util.logging.ConsoleHandler.level=SEVERE - ``` -- **Debug with Verbose Logs**: Use `-Dtest=` to focus on just one or two test methods, or one class, using more logging to debug the code: - ```bash - $(command -v mvnd || command -v mvn || command -v ./mvnw) -pl json-java21-api-tracker -Dtest=XXX -Djava.util.logging.ConsoleHandler.level=FINER - ``` -- **No Grep Filtering**: Use logging levels to filter output, do not grep the output for compile errors, just run less test methods with the correct logging to reduce the output to a manageable size. Filtering hides problems and needs more test excution to find the same problems which wastes time. - -## Modern Java Singleton Pattern: Sealed Interfaces - -**Singleton Object Anti-Pattern**: Traditional singleton classes with private constructors and static instances are legacy should be avoided. With a functional style we can create a "package-private companion module" of small package-private methods with `sealed interfacee GoodSingletonModule permits Nothing { enum Nothing extends GoodSingletonModule{}; /* static functional methods here */ }`. - -### Assertions and Input Validation - -1.
