In Java programming, two fundamental concepts,abstractionandencapsulation, play a major role in designing robust and maintainable code. While they both contribute to achieving modular and organized code, they serve different purposes. In this article, we’ll understand the difference between abstr...
Encapsulation and abstraction are two out of four pillars ofobject-oriented programming. Both principles help in designing a class so that the class can perform necessary functions, as well as, does not expose unwanted details to the other classes to avoid its misuse. In this post, we will un...
{ private: // we declare a as private to hide it from outside int a; public: // set() function to set the value of a void set(int x) { a = x; } // get() function to return the value of a int get() { return a; } }; // main function int main() { Encapsulation...

Interfaces are absolutelyabstractand cannot be instantiated; A Java abstract class also cannot be instantiated but can be invoked if amain()method exists. 5. When to Use? Always remember that choice between the interface or abstract class is not either/or scenario, where choosing anyone without ...
On the other hand, properties provide a level of abstraction by exposing access to the underlying data through methods called "getters" and "setters." Properties allow you to control access to the data, enforce validation rules, and perform additional logic when reading or writing the data....
Abstraction in Java Encapsulation in java with example Polymorphism in java with example Inheritance in Java Can we override static method in java Dynamic method dispatch in java Can we overload main method in java Difference between early binding and late binding in javaShare...
Destructive decoupling often goes hand in hand with the "interfaces everywhere" attitude. That is, the temptation to substitute every concrete class with an interface, even if that interfacedoes not represent an abstraction. So how would we rewrite the code above? Like this: ...
data type, or we can say it’s a blueprint or a prototype from which we can create the objects. A class defines a type of object, but it’s not an object. In C#, classes support polymorphism, the inheritance that provides derived classes and base classes, abstraction, and encapsulation...
In summary, AWT is a simpler, faster, and more lightweight UI toolkit that uses the native GUI components of the platform, while Swing is a more advanced, flexible, and portable UI toolkit that provides a rich set of GUI components and features....
