C. Clearly define the intended use cases for each overloaded method. Explanation: While there's no guaranteed way to eliminate all ambiguity with varargs, clear documentation and design choices can significantly improve code readability and reduce the risk of compiler errors or unexpected behavior. Here are key practices: Document the purpose of each overload: Explain when to use a fixed-argument method versus the varargs method. This helps maintainers understand the intended usage and avoid confusion. Use different parameter types for fixed arguments and varargs: If possible, choose distinct types for fixed parameters and the varargs parameter. This helps the compiler differentiate between methods more clearly during overload resolution. For example: Java void printMessage(String prefix, int count) { // ... } void printMessages(String prefix, String... messages) { // ... } In this case, the compiler can easily distinguish between printing a message with a count (first method) and printing multiple messages with a prefix (second method). Minimize the number of overloads with varargs: Overuse of varargs can lead to ambiguity. Aim for a clean design with a limited number of overload combinations. Consider alternatives: In some cases, using multiple fixed-argument methods might be clearer than varargs. Evaluate whether multiple methods with specific argument lists might enhance code readability and maintainability.
