Answer
Plain strings are error-prone. Frame the concept in practical terms so you can explain it during interview discussion.
Using plain strings to handle JSON can lead to errors because it doesn't account for complex data structures like nested objects or arrays. For example, if an API returns a JSON array of products, using plain strings might miss parsing nested product details like 'price' or 'availability'. Instead, a library like Jackson's ObjectMapper should be used to map JSON directly to Java objects, ensuring type safety and ease of access.
