Java 8 brought a few brand new features to the table, including lambda expressions, functional interfaces, method references, streams, Optional, and static and default methods in interfaces. We’ve already covered a few of these features in another article. Nonetheless, static and default methods ...

We can’t define interface static method for Object class methods, we will get compiler error as “This static method cannot hide the instance method from Object”. This is because it’s not allowed in java, since Object is the base class for all the classes and we can’t have one cl...
method signatures, default methods, static methods, and nested types. Method bodies exist only for default methods and static methods. Interfaces cannot be instantiated—they can only be implemented b 在Java编程语言,接口是参考类型,相似与类,可能包含常数、方法署名、缺省方法、静态方法和仅被筑巢的类型。
