No, in Java you cannot overload/override functions based on return types.

• In Java, method overloading is based on the number and type of parameters, not the return type.

• Method overriding is based on the method signature, which includes the method name, parameter types, and order, but not the return type.

• Attempting to overload or override a method based solely on return type will result in a compilation error.

PUT is used to update or replace an entire resource, while PATCH is used to update or modify a part of a resource.

• PUT is idempotent, meaning multiple identical requests will have the same effect as a single request.

• PATCH is not necessarily idempotent, as multiple identical requests may have different effects.

• PUT requires the client to send the entire updated resource, while PATCH only requires the client to send the specific changes to be made.

• PUT is typically used for updati...read more
