Java OOP

Java – What is OOP?

OOP is an acronym for Object-Oriented Programming.

Procedural programming involves creating procedures or methods to operate on data, whereas object-oriented programming focuses on designing objects that encapsulate both data and methods.

Object-oriented programming offers numerous benefits compared to procedural programming:

• OOP executes more swiftly and with greater ease.
• OOP furnishes programs with a coherent structure.
• OOP aids in maintaining Java code’s adherence to the DRY principle, streamlining maintenance, modification, and debugging processes.
• OOP enables the development of fully reusable applications with reduced code and expedited development timelines.

Remember, the “Don’t Repeat Yourself” (DRY) principle advocates minimizing code repetition. Centralize common code segments within the application and reuse them rather than duplicating them.

Java – What are Classes and Objects?

In object-oriented programming, classes and objects are the primary components.

Explore the following depiction to discern the distinction between classes and objects:

Another example:

In essence, a class serves as a blueprint for creating objects, while an object represents a specific instance of a class.

Upon creation, individual objects inherit all the attributes and behaviors defined within the class.

Further insights into classes and objects will be covered extensively in the upcoming chapter.
