📄️ Constructors In Java
Constructors in Java are special methods within a class that are used for initializing objects. They are called when an object of a class is created using the new keyword. Constructors have the same name as the class and may have parameters to set initial values for object attributes.
📄️ Inheritance In Java
Inheritance is a fundamental concept in object-oriented programming (OOP) and is a key feature of Java. It allows you to create a new class (called a subclass or derived class) based on an existing class (called a superclass or base class). Inheritance promotes code reuse, hierarchy, and the creation of more specialized classes.
📄️ Polymorphism In Java
Polymorphism is a fundamental concept in object-oriented programming (OOP), and it's a key feature of the Java programming language. It enables you to write more flexible and reusable code by allowing objects of different classes to be treated as objects of a common superclass. Polymorphism comes in two main flavors: compile-time (static) polymorphism and runtime (dynamic) polymorphism.
📄️ Encapsulation In Java
Encapsulation is one of the four fundamental Object-Oriented Programming (OOP) concepts, along with inheritance, polymorphism, and abstraction. It is a crucial concept in Java, and it involves bundling an object's state (fields) and behavior (methods) into a single unit known as a class. Encapsulation restricts direct access to some of an object's components, providing better control over data integrity and preventing unintended modifications.
📄️ Abstraction In Java
Abstraction involves creating a representation of an object or system that includes only the relevant and essential characteristics, while abstracting away less important details. This simplification allows programmers to concentrate on what an object does rather than how it achieves its functionality.
📄️ Interfaces And Abstract Class In Java
Java provides two key mechanisms, interfaces, and abstract classes, to achieve abstraction and build flexible, modular code.
📄️ Object Class In Java
In the realm of Java programming, the Object class holds a special place—it's the root of the class hierarchy, and every class in Java implicitly inherits from it. As a result, the Object class comes equipped with several crucial methods that lay the foundation for effective object-oriented programming.
