Java, one of the most widely used programming languages, fully embraces OOP principles, making it essential for developers to understand these concepts to write efficient and maintainable code. In this article, we will explore the four primary OOP concepts in Java: Encapsulation, Inheritance, ...
In the Java programming language, each class is allowed to have one direct superclass, and each superclass has the potential for an unlimited number of subclasses: A hierarchy of bicycle classes. The syntax for creating a subclass is simple. At the beginning of your class declaration, use ...

Just like a child inherits the characteristics of his parents and add specific new attributes of his own. With the help of Inheritance, we use the previously defined code but always Remembers, We are only using that code but not changing that code. Similarly, in C++, a new class can ...
Inheritance can be achieved in Java through two keywords: ·extends ·implements Use extends when there is some class and another class wants to use the property of that class so always one class extends another class. Whileimplementsare used when some interface is there and some class wants to...
What are the types of recursion? Recursion are mainly of two types depending on whether a function calls itself from within itself or more than one function call one another mutually. The first one is called direct recursion and another oneis called indirect recursion. ...
So by making our programs use ‘has-a’ relationship, what we are doing here is that we make our program use an instance of a class directly instead of ‘extending’ it from another class as we do in case of inheritance. The below diagram depicts both ‘is-a’ and ‘has-a’ relation...
