OOPs concepts in Java include inheritance, polymorphism, encapsulation, and abstraction.
Inheritance allows a subclass to inherit properties and methods from a superclass.
Polymorphism allows objects to take on multiple forms and behave differently based on their context.
Encapsulation hides the implementation details of an object and only exposes necessary information.
Abstraction allows for the creation of abstract class...
Interfaces define contracts for behavior, while inheritance allows for code reuse and polymorphism.
Interfaces allow for loose coupling and abstraction, enabling multiple implementations of the same behavior.
Inheritance allows for code reuse and extension of existing classes, reducing code duplication.
Polymorphism allows objects of different classes to be treated as if they were of the same class, simplifying code and i

An interface in software development defines a contract for classes to implement, specifying methods and properties.
Interfaces in programming languages like Java and C# allow for multiple inheritance by defining a set of methods that a class must implement.
Interfaces provide a way to achieve abstraction and polymorphism in object-oriented programming.
Interfaces are used to define common behavior that multiple classes c...
Encapsulation is the concept of bundling data and methods that operate on the data into a single unit.
Encapsulation helps in hiding the internal state of an object and restricting access to it.
It allows for better control over the data by preventing direct access from outside the class.
Encapsulation promotes code reusability and makes the code easier to maintain.
Example: In a class representing a car, the variables lik...
