Basically all Java tutorials will tell us that the Java interface method is public, abstract type, no method body.But in the JDK8, you can break through the boundaries of the OH.Suppose we now have an interface: Timeclient, whose code structure is

There are @optional keywords in protocol in Objective-c, and the method that is modified by this keyword is not required to be implemented. We can define a series of methods through an interface, and then selectively implement several of these

Beginners Java people will inadvertently define the constants in the interface, the only reason is that the interface can not be instantiated, and the use of the interface defined by the constant is not attached to the instance. This is mainly the
