![]() ![]() This can be used to create universal constants which can be called anywhere in the code ( without implementing that interface ). My current understanding is that interfaces allow for loosely connected classes to share methods of the same name, and that is quite helpful. ![]() The final modifier ensures the value assigned to the interface variable is a true constant that cannot be re-assigned. The value of the variable must be assigned in a static context in which no instance exists. Isn't implementing an interface and providing an empty implementation a bad design issue? though you document it, it goes against the concept of interface and is inconsistent as you may have an empty implementation of one method in one class, and another implementation in another class and the code will become inconsistent in the long run, making it unsafe. In java, Interface fields are implicitly public static final.And they must be initialized within the interface during declaration. First, I currently understand that interface fields are static final in their implementation. Interface variables are static because java interfaces cannot be instantiated on their own. ![]()
