Mutable getters: Avoid using mutable getters to prevent unexpected changes, thread unsafety, encapsulation principle violation, and potential corruption of object state in multi-threaded applications. Instead, return shallow copies or use immutable objects.
Using mutable getters in your code can lead to major issues, including unexpected changes, ripple effects, thread unsafety, and encapsulation principle violation. These problems arise because mutable getters allow external entities to modify the internal state of an object, leading to potential corruption and unintended behavior. To prevent these issues, it's recommended to return shallow copies of your collections or use immutable objects instead. This ensures object integrity and thread safety, especially in multi-threaded applications. Mutable getters also break encapsulation, which can lead to a loss of integrity and control. AI tools and generators might create this "getters" code smell if they prioritize simplicity and brevity over best practices. To detect mutable getters, examine the return types of your getters, and if they return mutable collections or objects, refactor them to return immutable copies or use immutable types. By avoiding mutable getters, you can prevent unintended modifications and ensure your objects remain reliable and predictable.
Code Smells: Regularly identifying and addressing code smells improves software quality, maintainability, and reduces risk of introducing new bugs or technical debt.
Identifying and addressing code smells can significantly improve the quality and maintainability of your software. Michael A. Jackson's quotes and tips in the "CodeSmell" series emphasize the importance of proactively seeking out and addressing these issues, rather than waiting for them to cause bigger problems. By understanding common code smells and their root causes, developers can make informed decisions about how to refactor and improve their codebase. This not only makes the codebase more efficient and easier to work with, but also reduces the risk of introducing new bugs or technical debt. So, regularly reviewing and addressing code smells should be a priority for any development team.
