Can A Concrete Class Extend Multiple Abstract Classes at Walter Pickney blog

Can A Concrete Class Extend Multiple Abstract Classes. It must not extend an abstract class without implementing its abstract methods: Instead, you can only create objects of concrete subclasses that extend the abstract class. Public class fancycar extends vehicle implements driveable { public string honk() { return beep; There must be an implementation for each and every method. In other words, we can say that any class which is not abstract is a concrete class. If you have two classes from which you'd like to use code, you'd typically just subclass one (say class a). It can also extend an abstract class or implement an interface as long as it implements all their methods. If a class extends an abstract class, then it should define all the abstract methods (override) of the base abstract class. This allows for polymorphism, where objects of. We can create an object of concrete class using the new keyword. If a concrete class extends an abstract class, it must provide concrete (non. Necessary condition for a concrete class: They can also implement interfaces and extend abstract classes: It is a complete class and can be instantiated. Concrete classes can extend abstract class in java or implement interfaces, but they must implement all the methods of the abstract class or interface they inherit.

It can also extend an abstract class or implement an interface as long as it implements all their methods.
