What is the difference between inheritance and implementation in Java?
so there are difference between inheritance and implementation is , inheritance inherit the parent class features and implementation is give a meaning to a defined idea or abstract method.Inheritance in java is one of the core concepts of Object-Oriented Programming. Java Inheritance is used when we have is-a relationship between objects. Inheritance in Java is implemented using extends keyword.Inheritance allows programmers to create classes that are built upon existing classes, to specify a new implementation while maintaining the same behaviors (realizing an interface), to reuse code and to independently extend original software via public classes and interfaces.

What is difference between inheritance and interface in Java : Inheritance is the mechanism in java by which one class is allowed to inherit the features of another class. Interface is the blueprint of the class. It specifies what a class must do and not how.

What is the main advantage of implementing inheritance

Code Reusability and Efficiency

Reduced Code Duplication: Inheritance reduces code duplication by allowing derived classes to reuse the properties and methods defined in the base class. Developers don't have to write the same code multiple times in different classes when a common functionality exists.

Which is better inheritance or encapsulation : Encapsulation allows us to hide implementation details and provide controlled access to the data and behavior of an object. Inheritance facilitates code reuse and supports hierarchical relationships between classes.

Java supports the following four types of inheritance:

  • Single Inheritance.
  • Multi-level Inheritance.
  • Hierarchical Inheritance.
  • Hybrid Inheritance.


Implementation inheritance is a relationship where a child class inherits behaviour implementation from a base class. Interface inheritance is when a child class only inherits the description of behaviour from the base class and provides the implementation itself.

What is the main purpose of inheritance

Thus, it concludes that the main aim of inheritance is to implement the concept of reusability, saving our time and resources and also creating better connections between different classes, and achieve method overriding.If two abilities are very similar and do some of the same functionality then the interface approach requires the code to be repeated in both classes, but with inheritance they can inherit from an abstract class that defines the functionality only once, allowing for it to change without having to change code in multiple …To declare a class that implements an interface, you include an implements clause in the class declaration. Your class can implement more than one interface, so the implements keyword is followed by a comma-separated list of the interfaces implemented by the class.

The disadvantage of class inheritance is that the subclass becomes dependent on the parent class implementation. This makes it harder to reuse the subclass, especially if part of the inherited implementation is no longer desirable.

What are the disadvantages of implementing inheritance : Cons

  • Tight coupling: Inheritance can lead to tight coupling between classes, which can make the code harder to maintain and modify.
  • Fragility: Changes to the base class can have unintended consequences on the derived class, which can make the code fragile.

What is the biggest advantage of inheritance : Advantages of inheritance

  • Reusability: Inheritance help the code to be reused in many situations.
  • Save time & effort: the above concept of reusability achieved by inheritance.
  • Data hiding: the base class can decide to keep some data private so that it cannot.

What are the 4 pillars of OOP

The Four pillars of OOPs, abstraction, encapsulation, inheritance, and polymorphism, are integral to understanding and using OOP. By using these four pillars of OOPs, developers can create programs that are powerful, maintainable, and extensible, making them a great choice for software development.

Several basic modes of inheritance exist for single-gene disorders: autosomal dominant, autosomal recessive, X-linked dominant, and X-linked recessive.The most important use of inheritance in Java is code reusability. The code that is present in the parent class can be directly used by the child class. Method overriding is also known as runtime polymorphism. Hence, we can achieve Polymorphism in Java with the help of inheritance.

Is implements considered inheritance : Inheritance is the ability of a class to reuse the attributes and methods of another class, while polymorphism is the ability of a class to behave differently depending on the context. One way to achieve inheritance and polymorphism in Java is by using the 'implements' keyword.
