Course Introduction：Interface concept: An interface defines a set of abstract methods and specifies the method signatures that a class must implement. Features: Contains only abstract methods, no concrete implementation. Declared as interface keyword. Multiple interfaces can be expanded. Role: Promotes decoupling and allows implementation checking at compile time. Forces subclasses to implement specified methods. Acts as a contract to ensure that the implementation has the expected behavior. Abstract class concept: An abstract class defines a contract that specifies the methods that subclasses must implement. Features: Can contain abstract methods and concrete methods. Declared as abstract keyword. Only one abstract class can be inherited. Role: Provide partial implementation, allowing subclasses to implement only specific behaviors. Force subclasses to inherit specific functionality. Reduce code duplication and promote code reuse. Choose interface or pump

Course Introduction：Interfaces and abstract classes are important concepts in Java programming, and they are both used to represent abstract types. This article will explore their similarities and differences, and how to use them effectively. Interface An interface is a special class that contains only abstract methods (unimplemented methods). It defines a contract that any class that implements the interface must implement these abstract methods. Interfaces are used to establish a unified interface between different classes to promote code portability. Abstract Method An abstract method is a method in an interface or abstract class that has no implementation body. When a class implements an abstract method, it must provide an implementation of the method. The characteristics of an interface include only abstract methods. Cannot be instantiated. Can inherit multiple interfaces. Supports multiple inheritance. Abstract class An abstract class is a special class that can contain abstract
