Assertion: inheritance's class | /r/CapableOf | implement interface
Facets:
value: with the same method signature
type: OTHER
Source sentences:
text: Therefore, the class that implements an interface has to provide the implementations or method definitions to all abstract methods in the interface.
text: A class can implement multiple interfaces even though it can derive from only a single direct base class.
text: So, a class that actually implements the interface should implement all the methods declared in the interface.
text: Note A class or struct can implement one or more interfaces.
text: All classes and structs that implement that interface must implement that set of members.
text: If you have default method in an interface, it is not mandatory to override (provide body) it in the classes that are already implementing this interface.
text: As you can see that the class implemented two interfaces.
text: In addition to this a class can inherit only from one abstract class (but a class may implement many interfaces) and and must override all its methods/properties that are declared to be abstract and may override virtual methods/ properties.
text: A class implements another interface.
text: A class can implement more than one interface, which can contain default methods that have the same name.
text: A class can implement any number of interfaces.
text: Abstract class can implement more than one interfaces, but can inherit only one class
text: Any class that implements an interface must implement the methods declared in that interface plus all the methods that are present in the super interface.
text: A class that implements an interface must flesh out the skeleton methods of the interface.
text: If a class that implements an interface does not define all the methods of the interface, then it must be declared abstract and the method definitions must be provided by the subclass that extends the abstract class.
text: When a class implements an interface, an object of such class can be encapsulated inside an interface.
text: This is perfectly fine because the interfaces are only declaring the methods and the actual implementation will be done by concrete classes implementing the interfaces.
text: These implementations are inherited by derived interfaces, and by classes that implement those interfaces.
text: So if a class implemented multiple interfaces with the same method signature, it was not a problem.
text: This means that if a class implements multiple interfaces, which define methods with the same signature, the child class would inherit separate implementations.
text: That’s why a java class can implement multiple interfaces, something like below example.
text: This means that if a variable is declared to be the type of an interface, then its value can reference any object that is instantiated from any class that implements the interface.
text: However, a class can implement one or more interfaces, which has helped Java get rid of the impossibility of multiple inheritance.
