Is apex only for inner classes?

It's not required for these classes to be inner classes, but it is a common implementation pattern. Apex only allows one level of nesting for inner classes, so deeply-nested JSON structures often convert to Apex classes with all levels of structure defined in inner classes at the top level.

Can you deserialize JSON into Apex?

In some situations, it's most beneficial to deserialize JSON into Apex collections of primitive values, rather than into strongly-typed Apex classes. For example, this can be a valuable approach when the structure of the JSON may change in ways that aren't compatible with typed deserialization, or which would require features that Apex does not offer like algebraic or union types.

Can Apex serialize JSON?

Apex can serialize and deserialize JSON to strongly-typed Apex classes and also to generic collections like Map<String, Object>and List<Object>.
