Concepts of JAVA!
Object implies a real-world entity, for example, a pen, seat, table, PC, watch, and so forth. Object-Oriented Programming is a technique or worldview to plan a program utilizing classes and objects. It streamlines programming and upkeep by giving a few ideas:
•Object
•Class
•Inheritance
•Polymorphism
•Abstraction
•Encapsulation
Object
Java Object
An object is any entity that has state and behavior. For example, a chair, pen, table, keyboard, bike, etc. It can be physical or logical.
An Object can be characterized as an instance of a class. An object contains a location and consumes some room in memory. An object can convey without knowing the points of interest of one another's information or code. The important thing is the sort of message acknowledged and the kind of response returned by the objects.
Example: A dog is an object because it has states like color, name, breed, etc. as well as behaviors like wagging the tail, barking, eating, etc.
Class
Collection of objects is called class. It is a logical entity.
A class can also be defined as a blueprint from which you can create an individual object. Class doesn't consume any space.
Inheritance
When one object acquires all the properties and behaviors of a parent object, it is known as inheritance. It provides code reusability. It is used to achieve runtime polymorphism.
Polymorphism in Java
Polymorphism
If one task is performed by different ways, it is known as polymorphism. For example: to convince the customer differently, to draw something, for example, shape, triangle, rectangle, etc.
In Java, we use method overloading and method overriding to achieve polymorphism.
Abstraction
Hiding internal details and showing functionality is known as abstraction. For example, phone call, we don't know the internal processing.
In Java, we use abstract class and interface to achieve abstraction.
Encapsulation in Java OOPs Concepts
Encapsulation
Binding (or wrapping) code and data together into a single unit are known as encapsulation. For example, the capsule, it is wrapped with different medicines.
A java class is the example of encapsulation.
ABC of Technology Training is an organization which offers a Unified Course which envelops all aspects of Java, Software Testing and associated aptitudes packaged into one bundle which is fundamentally required to clear an IT meet or becomes a Developer or a Tester. This course stretches out for multi-day - 500 hour which incorporates Java, J2EE, Frameworks, Manual Testing, Automation Testing (Selenium), Mobile Testing (Appium), MicroFocus-LeanFT (HPE Software Kit), SQL, HTML, CSS, Data Structures, Programming and Problem Solving, Technical Aptitude, Logical Reasoning, Verbal Reasoning, Non-Verbal Reasoning, Mathematical Aptitude, Soft Skill preparing and also 3 Projects (two on development and one on testing).
