In a typical design based on abstractions, where an interface has one or multiple implementations, if one or more methods are added to the interface, all the implementations will be forced to implement them too. Otherwise, the design will just break down. Default interface methods are an effici...

Within an instance member of an interface, this has the type of the enclosing interface.Modifiers in interfacesThe syntax for an interface is relaxed to permit modifiers on its members. The following are permitted: private, protected, internal, public, virtual, abstract, sealed, static, exte...
Default methodsandabstract methodsin interfaces are inherited like instance methods. However, when the supertypes of a class or interface provide multiple default methods with the same signature, the Java compiler follows inheritance rules to resolve the name conflict. These rules are driven by the fo...

There are many new language capabilities shown in that small code fragment. Interfaces can now include static members, including fields and methods. Different access modifiers are also enabled. The other fields are private, the new method is public. Any of the modifiers are allowed on interface ...
In my opinion, the answer is that by and large, developers are APIconsumers; relatively few are API authors. They do not generally appear in a java developer’s day-to-day coding life. However, default interface methods are an incredibly powerful tool that enable API authors to confer consid...
The@JvmDefaultannotation is going to be deprecated later. There’s no need to annotate each member with it; most probably you had to annotate all the interface methods with bodies, and it was quite verbose. Eventually, we want to generate method bodies in interfaces by default when your code...
