![]() ![]() ![]() You can set security restrictions that prevent access to private members if you need to restrict this ability. So I guess the creators of reflection allowed access to private members so that they didn't limit creativity. You can provide public constructors with parameters so the objects are in a valid state, and the fields can't be modified directly because they aren't public. This means that if another programmer wants to create an instance of this class outside of Hibernate then the interface is sensible. There are three steps that must be followed to use these classes. This means that when you design the classes it is going to populate you can make the no-args constructor private and also keep all the fields private. The reflection classes, such as Method, are found in. Hibernate uses the getDeclaredX() variants of the reflection methods. Hibernate creates the java objects using a no-args constructor and then populates the fields by using reflection to find and set them too. This product takes data in a database and automatically turns it into Java objects and vice versa. Similar to methods, reflection provides APIs to discover and retrieve the constructors of a class. Typically it performs operations required to initialize the class before methods are invoked or fields are accessed. For example take frameworks like Hibernate. A constructor is used in the creation of an object that is an instance of a class. (Actually, fields of any type must be set with compatible types. IllegalArgumentException when Setting a Field with an Incompatible Enum Type Fields storing enums set with the appropriate enum type. I assume you're asking why there is a method that returns private members at all, rather than asking why they split out the other method to return only public members. Code which attempts to instantiate classes using their default constructors should invoke Class.isEnum () first to determine if the class is an enum.
