What recommended technique can shorten a method with a long parameter list?

• A. Change the return type
• B. Optimize internal logic
• C. Break up method; create parameter object
• D. Use exception handling more effectively

Answer: (C)

When dealing with a method that has a long parameter list, breaking up the method and creating a parameter object is a highly effective technique. This approach promotes better organization and clarity in your code by encapsulating the related parameters into a single object. By using a parameter object, you simplify the method signature, making it easier to read and understand. This also allows you to pass multiple related values as a single unit rather than individual parameters, which can enhance maintainability. Additionally, this technique facilitates future changes in the method. If new parameters need to be added, updating the parameter object can be more straightforward than modifying the method signature directly. Consequently, creating a parameter object enhances the method's usability and comprehensibility, adhering to API design principles that favor simplicity and clarity in method interfaces.
