Why this Course? Why is this the best Course To Master Java Design Patterns?
Well, if you are here is probably because you've either looked online for tutorials or maybe watched a lot of youtube videos and still can't really understand Java Design Patterns.
You see, out there on the Internet, you can find a lot of information, but the problem is that everything is scattered around. Very frustrating to actually learn the right way since all you get is fragments of information. This is where this Java Design Patterns - The Complete Masterclass shines - it takes you from the beginning of understanding all the most important Design Patterns so you can actually start to understand and use them in no time. With the knowledge you gain from this course, you will gain the confidence to call yourself a True Programmer!

Facade Design Pattern and examples
Adapter Design Pattern
Strategy Design Pattern
Decorator Design Pattern
Observer Design Pattern
...and so much more...
My goal in this course is to give you. You need to gain the confidence you need and start writing code that's robust, efficient, and extensible!
Don't just take my word for it; see what my past students had to say about my courses and my teaching style:
"Very well thought-out course. It flows smoothly with great delivery. I have been developing Android Apps for several years, and I still found this course informative, relevant, and helpful. I would recommend everyone take this course if you are new to Android or returning for a refresher course." - Douglas Pillsbury.
"Great course. Very easy in understanding and friendly learning. Good Job, Sir. Thanks for this." - Muhammad Adnan
"I am delighted with this course. I have only attended the Android part because I had a basic knowledge of Java. I really like how Paulo teaches. He goes step by step, and you can understand everything. My first language is not English, but he speaks very; clearly, I can understand every word. Also, he is a happy guy, and you can hear that through the courses that he really loves what he is doing. " - Antal Bereczki
"This course is ideal for beginners. This guy is a good teacher. As I get deeper, I feel I am gaining more and more power...haha.
I honestly think this is the best money I have ever spent in my life. This course is worth the money 100 times over. OMG, this good.
Paulo, you are FANTASTIC !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!" - Sean
"So far one of the best courses and instructors I have experienced in Udemy." - Jim Landon
Just in case your Java skills are not to par yet, I have also added a Bonus Section at the end of the course so you can quickly get back to speed with Java and start working on building Android Apps!
Are you afraid that maybe since you are an experienced developer and have NEVER done Java before but are proficient in another OOP language, you won't learn Java Design Patterns? Take a look at what one of my students said about my course and teaching style:
"As a web developer, I always thought that learning Android development will be hard. But with this course, it's a piece of cake!" - Saša Lacković
Students love my course so much that they can't even contain themselves... Look at what one student wrote:
"If there's something more than 5 stars, I would have given to this course.
Really great content, along with a detailed explanation.
Keep going on by updating and enhancing the content of this course. Personally, I enjoy every lecture I attend.
PAULO... YOU ARE BEST OF THE BEST :)
Thanks a lot for this great course,
Best regards." - Bassel Nasief

I recently had the pleasure of taking a master class in design patterns with Paulo, and I can recommend his course with pleasure. As a programmer, I found his explanations and examples to be clear and concise, and I appreciate the effort he took to tailor his teaching style to the needs of each individual in the class. Paulo is a true expert in the field of design patterns, and his knowledge and experience is evident in every lesson. He was always well-prepared and able to answer any questions that arose. I particularly appreciated his use of real-world examples, which made the material more relatable and easier to understand. Overall, I feel that taking this course with Paulo has greatly improved my understanding of design patterns, and I would highly recommend it to anyone looking to improve their programming skills. Paulo is an exceptional teacher, and I look forward to taking more classes with him in the future.

The good: the course isn't just a theoretical explanation, every pattern is demonstrated by writing a bit of actual code. This makes for one of the better explanation/demonstration of the first couple patterns that I've seen. The bad: the quality drops dramatically through the course. The more complex patterns are explained poorly, sometimes borderline misrepresented. The examples don't live up to the standard either - some of them only seem to very superficially resemble the patterns without actually providing its function. The ugly: while over-engineering of code would be acceptable or even expected in a tutorial that tries to showcase simple examples of patterns that often only make practical sense when the problem complexity demands, the code in some of the examples smells in other, much less acceptable ways Overall, if you want to learn about design patterns, you should probably look for a different course. This one isn't terrible and it may help you get a better grasp of a few most basic ones, but as a whole it's not worth it.

Godd introduction to design pattern, explanations are clear and it is quite easy to code along with the instructor even at x2 speed. Despite the course use Java as programming language to show the power of the different patterns the concepts can be used also in other languages, like Python for instance, therefore I'd suggest this to everyone who is looking for methods to enanche maintainability of code in any OOP language.
By SIMON Franck on 10/14/2020
Excellent, with good exemples
By Rahul Kalia on 10/8/2020
Does not provide engaging content delivery.
By Mark Sunghun Park on 8/23/2020
The examples are not very good to understand the pattern and the explanations are bit verbose.
By Raghavan on 7/18/2020

By Stanley Kam on 5/25/2020
This is a very good learning material for all the software developers to create a flexible and maintainable source code !
