In this example, the Duck class inherits from both Flyable and Swimmable. Capabilities of Duck: The Duck class can now use the fly method from the Flyable class, the swim method from the Swimmable class, and its own quack method. This demonstrates how Duck combines functionalities from ...
In the above example, we see how resources of the base class are reused while constructing the inherited class. However, the inherited class can have its own instance attributes and methods. Methods of the parent class are available for use in the inherited class. However, if needed, we can...
Inheritance is one of the fundamental principles of Object-Oriented Programming (OOP) that allows one class (the child class or subclass) to inherit fields and methods from another class (the parent class or superclass). This promotes code reuse, modularity, and better maintainability. In this a...
Inheritance is a fundamental concept in object-oriented programming (OOP) that allows a class (called a subclass or derived class) to inherit properties and behaviors from another class (called a superclass or base class). In Python, a subclass can inherit attributes and methods from its superc...

The word 'parent', while used in some DOM items, is free for the JS language itself, so let's call it parentin this example: Cat.prototype = new Mammal(); Cat.prototype.constructor=Cat; Cat.prototype.parent = Mammal.prototype; ... Cat.prototype.haveABaby=function(){ var theKitten =...
In inheritance, the child class acquires all the data members, properties, and functions from the parent class. Also, a child class can also provide its specific implementation to the methods of the parent class. For example, In the real world, Car is a sub-class of a Vehicle class. We...
The "@Override" is known as annotation (introduced in JDK 1.5), which asks compiler to check whether there is such a method in the superclass to be overridden. This helps greatly if you misspell the name of the method to be overridden. For example, suppose that you wish to override met...
Here we modified the example for Single inheritance such that there is a new class Puppy which inherits from the class Dog in turn inherits from the class Animal. We see that the class Puppy acquires and uses the properties and methods of both the classes above it. ...
