141 Java Refactoring With Modern Features

What it does

This skill assists with refactoring Java codebases, leveraging modern Java features to improve readability and maintainability. It can identify opportunities for simplification, extract methods, and apply design patterns. The agent uses this skill to modernize legacy code and adhere to current best practices.

When to use it

• You need to clean up a large, complex Java class with duplicated logic.
• You want to convert procedural code into more object-oriented structures using design patterns.
• A codebase needs modernization to take advantage of recent Java language features (e.g., records, sealed classes).
• You're facing performance bottlenecks in existing Java methods and need assistance optimizing them.

Key capabilities

• Method extraction
• Design pattern application
• Simplification of complex logic
• Modern Java feature utilization

Example prompts

• "Refactor this method to use a record instead of a getter/setter pair."
• "Extract the duplicated code in this class into a separate helper function."
• "Apply the Strategy pattern to handle different payment processing methods."

Tips & gotchas

This skill assumes familiarity with Java programming and basic refactoring principles. The agent may require context about existing design choices or constraints within the project.
