Inheritance and polymorphism works exactly the same way in C#. However, c# requires the virtual keyword for methods that you want overridden in inheriting subclasses, so I'm guessing that you didn't use virtual, hence you got the different result.
Plus it is said if I do not want to use this and do it rather in an old fashioned Java way I have to implement the the equals(), toString(), and the hashCode() methods of the Object class and also the annotation type method of the java.lang.annotation.Annotation class.
An interface in java is a blueprint of a class. It has static constants and abstract methods only.The interface in java is a mechanism to achieve fully abstraction. There can be only abstract methods in the java interface not method body. It is used to achieve fully abstraction and multiple inheritance in Java.
As i understand the inherited class should inherit also variables, you got it wrong, instance variables are not overriden in sub-class. inheritence and polymorphism doesnt apply for instance fields. they are only visible in your sub-class if they are marked protected or public. currently you have super class variable marked private. no other class can access it. mark it either protected or ...
Inheritance is a Parent Child Relationship Inheritance Means Is A RelationShip. Inheritance in java is a mechanism in which one object acquires all the properties and behaviors of parent object. Using inheritance in Java 1 Code Reusability. 2 Add Extra Feature in Child Class as well as Method Overriding (so runtime polymorphism can be achieved).
In short When you overload a method in Java its method signature got changed while in case of overriding method signature remains same but a method can only be overridden in sub class. Since Java supports polymorphism and resolve object at run-time it is capable to call overridden method in Java
I have a question about inheritance and casting in Java. I have the following two example classes and a test class, and I state my question after the classes: public class Automobile { public ...
As Java does not allow multiple inheritance, records cannot extend any other class. Consider, for example, the following record Point : public record Point(double x, double y) {}
I think it is the Java definition of inheritance. – OscarRyz. Commented Jan 17, 2011 at 18:09.
The Java language doesn't provide a way to "remove" or "disable" a method in a subclass. That would violate the substitutability principle and would break polymorphism. A subclass cannot remove visible members from the parent classes API.
