Answer
Relying on string operations leads to brittle code.
Using plain string operations to handle JSON is error-prone and can result in brittle code that breaks easily with data changes. This approach lacks structure and type safety, increasing the likelihood of runtime errors. Instead, using a library like Jackson ensures robust parsing and serialization. For example, manually extracting fields from a JSON string is less reliable than using ObjectMapper to map to a Java object.
