Interface (interface) is another important technique provided by Java, which is very similar in structure to abstract classes and has data members and abstract methods, but it differs from the abstract class in the following two points:1, the data

The interface syntax provided by Java is designed to separate the interface from the class to form an independent body.First, join us to define this cup interface:Interface cup{ void addwater (int w); void Drinkwater (int w);}Interface,

The abstract modifier can modify classes and methods.(1) The abstract modifier class, which makes this class an abstract class, will not generate an object instance, but can be used as the type declared by the object variable (see later instance),
