We know that Java doesn’t allow us to extend multiple classes because it will result in the “Diamond Problem” where compiler can’t decide which superclass method to use. With the default methods, the diamond problem would arise for interfaces too. Because if a class is implementing both...

Re: (Case 1399413) Crash when using default methods of a generic interface I have recently addressed this (and other default interface method issues) in our fork of Mono. https://github.com/Unity-Technologies/mono/pull/1551 This fix will be available in a future 2022 release of Unity. I ...

Java gives you several options when implementing an interface with default methods. The tutorial documentation states: When you extend an interface that contains a default method, you can do the following: Not mention the default method at all, which lets your extended interface inherit the default...
