Gson

Gson can serialize and deserialize Java objects without needing source code modifications or annotations, making it ideal for legacy or third-party code where annotations are not feasible.

It fully supports Java Generics, handling complex type hierarchies that other libraries might struggle with, as emphasized in its design goals.

Provides straightforward methods like `toJson()` and `fromJson()`, reducing the learning curve for basic JSON operations, which is a core feature highlighted in the README.

Allows custom serializers and deserializers for objects, enabling fine-grained control over JSON representation, as noted in the key features.
