Javadoc Documentation Quiz: Test Your Knowledge of @param and @return

📚 Quick Study Guide

• 🏷️ The `@param` tag is used in Javadoc to describe the parameters of a method or constructor. Each `@param` tag should specify the name of the parameter and a description of its purpose.
• ➡️ The syntax for `@param` is `@param parameterName description`. For example, `@param name The name of the person.`.
• ⏎ The `@return` tag is used in Javadoc to describe the return value of a method. It should only be used for methods that actually return a value.
• ✅ The syntax for `@return` is `@return description`. For example, `@return The greeting message.`
• 💡 If a method returns `void`, you should *not* use the `@return` tag.
• 🔗 Both `@param` and `@return` tags help in generating clear and understandable API documentation.
