Course Description
Best in class course if your objective is to build a Solid Foundation on OOPs and get your basics strong.
This course Course Object Oriented Programming & Design in Java is created with a clear objective in mind to build a solid foundation in Object Oriented Programming.
Because Solid and Strong Basics can lead to solve any programming problem! and help to write more elegant Machine and Human friendly code.
Object Oriented programming is there for quite a while now but we found that the course covers either only programming syntax and concepts of OOPs or Design Principl and patterns.
It is essential that when you start learning OOPs you should also learn many other related things like Design Principles, Object oriented design and Design Patterns as well because without learning these concepts your knowledge portfolio for OOPs is not complete.
So we bring to you this course where we will not only cover Object Oriented Programming concepts in Java but also Design Patterns, and Design principles along with best practices and OOPs philosophy.
This course also have sections where we will discuss about OOPs philosophy that will improve your thinking in Object oriented world.We have also created a small section on UML where we will discuss mainly class diagram and Sequence diagram that will help us learning design patterns.
Outline of what we have covered in this course
Prerequisites to Learn OOPs
Classes, Objects
Variables-Methods-constructors
packages, import keyword
Access Modifiers
Non-Access Modifiers
You may skip this section if you already know these concepts. After completing the same as we will be prepared to start the Journey. We will start discussing the actual OO concepts
OOPs Concepts
Data Hiding
Interfaces and Abstract class
Abstraction
Encapsulation
Inheritance - ISA relationship
Types of inheritance
Association with concepts of aggregation
HAS-A Relationship and composition
Polymorphism - Overloading and overriding
This section will cover the basics of OOPs concept related to Java and in general.
In Next section of the course we will Quickly discuss some philosophical Angles of OOPs to improve your thinking in Object Oriented world. This section will not have
much of a coding but will after completing this you will certainly feel more confident and connected to Object Oriented World.
After you start thinking clearly in OOPs we will start some of the very Important Design Principles in OOPs. These principles are the De Facto standard for object Oriented design for several years.
Design Principles
SOLID principles
DRY
KISS
YAGNI
SLAP
After completing this section you will be very confident and artistic in Object oriented programming.
After completing this we will have a section on Quick UML where we will discuss Class and Sequence Diagram because that is necessary to learn Design Patterns
UML
Class Digram
Sequence Daigram
We will use a lot of Sequence diagram and Class diagram in while discussing Design Patterns.Then we will come to a very popular topic in OOPs world and that is Design Patterns.We will discuss all 23 GOF design Patterns with the help of UML Code and Sequence diagram.
Creational Design Patterns
Prototype Design Pattern
Builder Design Pattern
Singleton Design Pattern
Factory Method
Abstract Factory Design Pattern
Behavioural Design Patterns
Chain Of Responsibility Pattern
Command Design Pattern
Interpreter Design Pattern
Iterator Design Pattern
Mediator Design Pattern
Memento Design Pattern
Observer Design Pattern
State Design Pattern
Strategy Design Pattern
Template Design Pattern
Visitor Design Pattern
Structural Design Pattern
Adapter Design Pattern
Bridge Design Pattern
Composite Design Pattern
Decorator Design Pattern
Facade Design Pattern
Flyweight Design Pattern
Proxy Design Pattern
After completing this we will discuss some of the coding best practices
Best practices.
Technical Debt
High Cohesion
Loose Coupling
Primitive Obsession - Code smell
Comment why not what
Hope this should be enough for you to become comfortable in Object Oriented programming and design in Java.
We have crafted the content, code examples and all other stuff in a way so that by end of this complete course you start feeling extremely comfortable and Confident in Programming OOPs.
So I am excited to welcome you again to this course hope we will have a very fruitful Journey with a clear objective to learn OOPs and OOPs design.
All the Best in building a SOLID foundation.
This course come with a 30 Days Money back guarantee so do't worry if it does not fit into your needs.

Good and complete course. However the English accent that is spoken is sometimes difficult to understand. Correct subtitles could be a good support (now is auto translated, and not always correct)
By Kristina Nedelkovska on 6/22/2023
The lectures are really well structured and there is a code example for every topic. It's a really good course for OOP. The only bad thing is the poor English pronunciation.
By Akanksha Prasad on 4/30/2023
It was a great course, and I learned a lot from it. But the lessons which were more than 10 mins long could have been split because it's difficult to focus for long durations.

It's a great course. The trainer explains the concepts very clearly & giving good examples in each topic. Thank you!
By Anonymized User on 11/9/2022
I highly recommend this course who are seeking clarity ans strong basics. Ideally I give reviews and star ratings at end of course or don't give at all. But right now I in middle of section 4 - philosophy behind OOPs. I can't resist to write down review. Course structure , its representation, explanation examples and its detailed comprehension is very good for beginner as me, who don't have computer/programming background. Thank you for this course and efforts, from heart❤️.
By Nirdesh Pandey on 4/24/2022
Overall good course but, the design principle and Patterns section is a lot. I mean while attending the session its fine post all sessions its all merging and confusing and everything sounds the same.
By Pedro Luiz Nogueira Mendes on 2/15/2022
I've been studying some of BasicsStrong courses and they have been literally a deal breaker for me, I was tired of searching for courses and only ending up in courses that couver only the basics. They deep really dive into concepts, and it's been a really good experience for me!!!

Hard to understand instructor. Explanations not always clear. Sometimes it seemed the instructor was unsure about how to explain a topic. One or two major errors in design pattern logic.
By Darren Finch on 4/23/2020
This course was pretty good. It wasn't anything above my expectations, but I definitely learned a lot. Solid course, would recommend to anyone wanting to get a solid foundation with software design. (no pun intended)
By Ranju vyas on 10/4/2019
This is one of the best courses I found over the internet for reading OOAD and OOPS - Great for beginners! OOAD Concepts are very cristal and clear.
