Customizing JSON with Gson

You are working on a legacy app that keeps track of local businesses using a Business class. You are making a custom serializer that implements the JsonSerializer<T> interface. Some of the field names are a bit wordy, so you are tasked with streamlining the names when they get serialized to JSON. In particular, the field whatKindOfBusiness seems a bit excessive.

public class Business {

    private String whatKindOfBusiness;

    public String getWhatKindOfBusiness() {
        return whatKindOfBusiness;
    }

    // other various fields, getters, setters, constructor, methods, etc...
}

Given a Business object business that is being serialized into a JsonObject called businessJson, add to it the category property that will be assigned the value stored in whatKindOfBusiness.

public class BusinessGsonSerializer implements JsonSerializer<Business> {
     
    @Override
    public JsonElement serialize(Business business, Type type,
        JsonSerializationContext jsonSerializationContext) {
        
        JsonObject businessJson = new JsonObject();
        
        // Add line of code to customize the field name when serialized

        return businessJson;
    }
}
