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...

Performance Considerations of Inheritance in Java While inheritance promotes code reuse, it can impact memory usage and performance if not used wisely. Key considerations include: Memor...
For example: • Cat Felidae (猫科) mammal (哺乳) amniote (脊椎) Animal Commons of Tom and Mimi : • You may have knowledge of them even you never see them. Differences between Tom and Mimi : • Specific features: Weight, Fur, Color of Eyes, etc… 9-22/69 • Two Kinds of...
Example of inheritance in Python: class Animal: def __init__(self, name): self.name = name def speak(self): return "Unknown sound" class Lion(Animal): # Lion class inherits from Animal class def speak(self): return "Roar!" class Tiger(Animal): # Tiger class inherits from Animal clas...
Some OOP languages have the concept of a pure virtual class...one which cannot be instantiated itself, but only inherited from. For example, you might have aLivingThing class which Mammal inherited from, but you didn't want someone to be able to make a LivingThing without specifying what ...
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...
In Hierarchical inheritance, more than one child class is derived from a single parent class. In other words, we can say one parent class and multiple child classes. Python hierarchical inheritance Example Let’s create ‘Vehicle’ as a parent class and two child class ‘Car’ and ‘Truck’...
Example openclassvehicle{var price:Int=0constructor(price:Int){this.price=price}}classcar : vehicle{var name:String=""constructor(name:String,price:Int):super(price){this.name=name}} Kotlin Overriding Member Functions In inheritance where base class and derived class have same function declaration...
Inheritance Code Example in Java Let’s say we have classes Vehicle and Car. Since a car is a vehicle in real life, we can create a class hierarchy where the Car class extends the Vehicle class, inheriting all the properties and behaviors of the Vehicle class and adding its own specific...
