Use when you need to review, improve, or refactor Java code for object-oriented design quality — including applying SOLID, DRY, and YAGNI principles, improving class and interface design, fixing OOP concept misuse (encapsulation, inheritance, polymorphism), identifying and resolving code smells (God Class, Feature Envy, Data Clumps), or improving object creation patterns, method design, and exception handling.

Java Object-Oriented Design Guidelines

Review and improve Java code using comprehensive object-oriented design guidelines and refactoring practices.

What is covered in this Skill?

Fundamental design principles (SOLID, DRY, YAGNI)
Class and interface design: composition over inheritance, immutability, accessibility minimization, accessor methods
Core OOP concepts: encapsulation, inheritance, polymorphism
Object creation patterns: static factory methods, Builder, Singleton, dependency injection, avoiding unnecessary objects
OOD code smells: God Class, Feature Envy, Inappropriate Intimacy, Refused Bequest, Shotgun Surgery, Data Clumps
Method design: parameter validation, defensive copies, careful signatures, empty collections over nulls, Optional usage
Exception handling: checked vs. runtime exceptions, standard exceptions, failure-capture messages, no silent ignoring

Scope: The reference is organized by examples (good/bad code patterns) for each core area. Apply recommendations based on applicable examples.

Constraints

Before applying any OOD changes, ensure the project compiles. If compilation fails, stop immediately — do not proceed until resolved. After applying improvements, run full verification.

MANDATORY: Run ./mvnw compile or mvn compile before applying any change
SAFETY: If compilation fails, stop immediately and do not proceed — compilation failure is a blocking condition
VERIFY: Run ./mvnw clean verify or mvn clean verify after applying improvements
BEFORE APPLYING: Read the reference for detailed examples, good/bad patterns, and constraints

When to use this skill

Review Java code for object-oriented design
Refactor Java code for object-oriented design
Improve Java code for object-oriented design
Fix OOP concept misuse in Java code
Identify and resolve code smells in Java code
Improve object creation patterns in Java code
