SUPER CHARGE OF YOUR PROGRAMMING CAREER and acquire some seriously marketable skills!

What Makes This Course Stand Out?

  • Comprehensive and Practical Approach: Learn core Object-Oriented Design (OOD) principles and best practices through hands-on coding exercises.

  • Master SOLID Principles: Discover and master the five crucial OOD principles.

  • Deep Dive into Design Patterns: Learn and apply the most essential design patterns used in professional software development.

  • Homework with Solutions: Reinforce learning with carefully designed assignments and step-by-step solution videos.

  • Career-Ready Skills: Move beyond syntax and develop the ability to architect scalable, maintainable software.

Why This Course Is Essential:

Just because you learned how to use a hammer doesn't mean you are ready to construct a building. Similarly, It's not enough to just understand a programming language. That's just a tool that can be used to develop various programs. The real craftsmanship is in software DESIGN. 

This course is designed to take a junior level programmer with limited knowledge about object orientation to a competent level object oriented software designer! I expect you to understand the basics of loops, methods and conditionals in Java. You'll be completing hands-on HOMEWORK Exercises through out the course! I have provided detailed video solutions to the exercises so that you can check your answers and get step by step instructions on how to tackle the object oriented design assignments.

You can find plenty of resources online for solving a programming puzzle or practicing algorithms. But… when it comes to object oriented design,  admittedly, there is limited material out there for you to practice. So  in this course, we use a LEARN-BY-DOING  approach to explore a series of progressively challenging exercises to  discover the 5 core object oriented design PRINCIPLES summarized by an  acronym called SOLID: 

(S). Single Responsibility   

(O). Open/Closed   

(L).  Liskov Substitution   

(l ). Interface Segregation   

(D). Dependency Inversion   

During this journey you'll get practice applying some of the most important DESIGN PATTERNS that competent developers must have under their belt. There are so many design patterns out there, but we'll be thoroughly covering only the most important ones. Save yourself the time from learning all the design patterns and going on a design frenzy. Focus on the 20% that covers 80% of the scenarios and add miles to your programming efficiency. 

These cover 80% of patterns used out there in professional software development.   

1). Strategy Pattern   

2). Observer Pattern   

3). Builder pattern   

4). Factory method pattern   

5). Template Method Pattern   

6). Singleton Pattern 

The topics can be applied to pretty much any object oriented language. But, we'll be using Java, so I expect you to be familiar with the basic language constructs such as classes, methods and interfaces. But don't worry if you don't know about these, I've taken the time to create 6 comprehensive prerequisite lessons on introduction to object orientation. In these lessons, new comers can learn about the basics of object orientation such as: 

1). Classes and objects   

2). Inheritance and polymorphism,   

3). Interfaces and abstract classes.   

I'm certain that, by practicing the concepts covered, you'll make a substantial leap forward in your programming career. I hope to see you in the coming lessons.

This course offers lectures on practical software development topics to immediately impact your programming skills. Things you can take to your interview and feel confident in your abilities!

KEY BENEFITS OF MASTERING OBJECT-ORIENTED DESIGN

Mastering Object-Oriented Design (OOD) principles is crucial for building scalable, flexible, and maintainable software.

  • Gain an Industry Edge: Employers value developers who think in terms of design rather than just writing code.

  • Write Cleaner, More Efficient Code: Learn to eliminate code smells and improve modularity and reusability.

  • Ace Technical Interviews: Most top-tier companies assess design skills, not just coding ability.

  • Future-Proof Your Career: OOD principles and design patterns are applicable across multiple programming languages, not just Java.

KEY TAKEAWAY

By the end of this course, you’ll not only understand Object-Oriented Programming but also apply SOLID principles and essential design patterns to write professional, high-quality software.

Instructor Details

Job Ready Programmer

You can’t learn programming from reading books or online fill-in-the-blank type tutorials. Especially the online tutorials with browser based exercises where you code directly in your browser. The problem with that approach is that it doesn’t provide practical experience. It provides an illusion of learning something as it tugs you along to complete an assignment that’s more of a fill-in-the-blank type problem. A student feels like they’ve learned something but that knowledge does not stick. Unfortunately that experience will not help in an interview nor an actual project. Valuable time ends up going to complete waste. At JRP (JobReadyProgrammer), we don’t follow hype. We do what works! We take a traditional route to teaching how to code advancing slowly & patiently in the lectures often repeating key concepts in multiple different ways to help students really solidify the knowledge and mold their foundation to discover how to code properly and then boy do we test the skills! Students are put right in the middle of a practical real-world programming assignment to apply everything they've learned. So enough of those “key in the next few commands to fill in the puzzle and we’ll advance you” kind of tutorials. Here you’ll need to roll up your sleeves and get to work on solving practical programming assignments.

Nicely explained the basic concepts

By Rupahli Garg on 11/7/2020

Detailed and easy

By Sudeepta Das on 10/26/2020

very nice. good to know that I implement the strategy pattern in day to day work but I was not aware of it. thanks!

By Chris Scrivo on 10/11/2020

Very clear and well thought out

By Ximing Song on 10/2/2020

The lecturer's teaching pattern is moderate and he skipped some of the unnecessary clips without me even noticing that. His tone did not fluctuate that much but I could feel he has prepared for the lecture for a long time.

By Collin M. Morudi on 9/26/2020

This course is awesome! I'm really excited to have found this course and I'm looking forward to learn more from it. I love the way the instructor teaches.

By Natalie Scheuble on 9/26/2020

I have seen other tutorials from this instructor. He is simply the best - and I have looked at many other tutorials.
He explains design patterns brilliantly.

By Youchen Ren on 9/16/2020

Pros:
1. Exercises provided;
2. Concise and easy to understand;
Improvements needed in my point of view:
1. Better if more exercises can be provided;
2. Better if instructor can use IntelliJ (Community version is also free) rather than Eclipse.
But overall, it's nice! thank you Imtiaz!

By Carlos Giraldo on 9/15/2020

Good material. Unfortunately the instructor doesn't respond students questions or doubts.

By Shankaran E R on 9/13/2020

Imtiaz's explanation of basics of a high quality yet simple enough to grasp. The course covers the basics so clearly and deep as well as the topics which of relevance to the day to day tasks.

By Istvan Szollosi on 9/5/2020

Good, understandable presentation, nice examples, so its good job.

By Marshall Tower on 8/22/2020

This program started off really good but only does downhill. The intro video and prerequisites are bang on but ends up feeling like false advertising. What worse is that the best parts are literally free on youtube which alone is a third of the course. Principles are blended together with patterns so they're never really clear. The course starts with explaining "why" you would do something to help show their importance but then stops half way through. Almost feels like the content was ripped from another larger course and wasn't completed properly. I was excited to see that maybe there was additional content since the last lesson says "Lifetime Access to All My Course" which of course aren't even free (like $175) and are through his side company but are basically the same content as on Udemy; I'm frankly surprised the Instructor hasn't been kicked off. Worst of all the homework "examples" which are really what should have been the meat of the course are sloppy, mismatched, and just plan wrong. A lot of times the outline of the homework problem doesn't even line up with the answer or even the answers aren't even included. Quite appalled this course.
