I was actually confused by the technical jargon that comes with the explanation of design patterns and this video cleared up the confusion. Years old, but still useful. Cheers!

@rajeshkohir5736 7 лет назад

Please post remaining design patterns i.e Observer,Decorator etc.Your teaching is really nice

@vnm_8945 6 лет назад

I like a lot how you're teaching I'm subscribed now, I wish you had more videos about design patterns and algorithms and data structures. ty for your work!

@basaveshbr3925 7 лет назад

you are simply great sir!!! i got inspired by the way you explain and makes it so simple. woww!!!

@webchild9043 3 года назад

You can use CTRL+D to delete a line. By the way amazing vidoes

@ANITARAI28 6 лет назад

This video is very helpful for my exam. I would really appreciate if you give more practical example.

@kaushikmangaprasad4575 7 лет назад

Wouldn't it be better to pass in Leaf instances into the constructor or use a builder pattern to construct the Composites there by referencing them with Component instead of Composite?

@dianal7610 7 лет назад

Best tutorial ever, thank you a lot, easy to understand even for beginners.

Thank you Navin for the great videos, you are an awesome teacher =)!

@khalidben9940 7 лет назад

amazing as usual. I enjoyed watching this video

@bipros7 7 лет назад

Superb explanation sir....Can you pls tell me what's the role of composite pattern in it industry????Is it kinda database manipulation?

At the beginning of these tutorials, we were told design patterns were created with two things in mind, "Composition over inheritance" and "Code for interface, not implementation." But here, we are coding to implementation, not interface. (With changing component to composite to use the addComponent() method. With this example, why are we not able to use the addComponent() method if we are using Component as the type, but instantiating a new Composite? And doesn't this go backwards on what is one of the rules for design patterns? Great work with the video and I understand the Composite design pattern through this, but these two hang ups are making me a bit confused. Hoping someone can clear this up for me. Thanks future person. :)

excellent tutorial naveen

@mgtowindia9549 6 лет назад

thank you sir... better than derek bannas

@anonymous7851 6 лет назад

think they supplement each other well. I find derek bannas usually a good source but definitely needed some help after his video on composite pattern

@bobonaqa 5 лет назад

i never understand derek bannas design pattern tutorials, this is so much better

@SercanSavranOfficial 5 лет назад

I'm losing focus in his tutorials because of the emphasizing... He sounds like an auctioneer on a fast talking contest.

@Keyakina 6 лет назад

3 things: 1) Why does the constructor calls super(); You can't initialize a interface right? 2) What if a leaf has 2 composition , so that means it would be in 2 different compositions so the price would count double? 3)How would this look like in real life? I mean, thats a HUGE and main?

@surajgoenka 4 года назад

What if I want to do subtotal of prices like Ram 1500 CPU 5000 Total Motherboard price 6500 HDD 3000 Total cabinet price 9500 Monitor 5000 Mouse 500 Keyboard 1000 Total peripheral device 6500 Total computer price 22500

@nagendrapyma1539 4 года назад

soo useful vides keep it up

@_-6912 4 года назад

Hi Naveen, why dint you complete all the design patterns? Also, video qualities are good but not lucrative, see Joma videos for his video lucrative quality.

@arielsp18 7 лет назад

How would you implement a method that returns the total value (sum cost of all components) of the computer?

@Keyakina 6 лет назад

The computer is a composite. It implements the component interface so it must have a getPrice() method. This composite class contains an Array of his own composites or leafs, he iterates trough it ( with a forloop) and you can add a variable (local or global) to the composite, doing in every iteration TotalValue += c.getprice

@denisr.8248 5 лет назад

its good video

@himanshupoddar1395 Год назад

None of the youtube tutorial provide example of what's the problem and how the same can be solved with composite design pattern. Everyone just starts with the pattern directly. Its really not useful for most of the beginners.

@harishsahu1310 5 лет назад

Side video of yours, make it more engaging. Content is good and easy to understand as always.

@ThePalashgupta 5 лет назад

when you are planning to add tutorials for all other Design Patterns ?

@SuyashNande 7 лет назад

If you show the UML diagram for the implementation. it would be good and also much easier for you to explain.

@destinoo1792 3 года назад

Was kinda confused at the start, but in the moment you started the declaration of the objects everything make sense and i could understand the design pattern. Thank Navin!

@denismugane2765 4 года назад

This confuses me with template,decorator and builder design pattern

@myquoraismine2953 5 лет назад

Better than Derek Banas, I came back heard after watching Banas composite design pattern tut, but as always real-world example nail it, u nailed it. Thanks much. Keep it up. Nice work. Didn't expect from thumbnail ,,😋. But u made ease.

@dhanalakshmi-zz2ry 6 лет назад

can you please put more videos on design patterns

@ganeshnimbolkar869 5 лет назад

you made it very much simple with real life example .. Thanks a lot

@SuyashNande 7 лет назад

I liked this video because it explained the concept well. But the way you deliver can be improved. Please try to speak slowly and clearly, in this way there should be less chances of error.

@anonymous7851 6 лет назад

Also maybe don't have the interface component be named so closely to composite because it was widly confusing at times.

@aimforgameitalia3225 2 года назад

@sivakrishnat5471 3 года назад

Is composition same as composite design pattern?

@hinasheikh2162 6 лет назад

waht is the alternative pattern of composite pattern

@jackfrost8969 6 месяцев назад

This was complicated at first but after writing the code by myself and analyzing it further on my own I was able to grasp it.

@Divv 7 лет назад

Very well explained. Good example also!

@qatest1204 4 года назад

Hi Navin, Could you please add more tutorial for all design patterns.

@partyhardwithme 6 лет назад

Very clear example, good thing you used an inferface instead of an abstract class full of "UnsupportedOperationException". Also, i liked that you didn't go through the recursive getPrice() example it really confuses people of understanding how the pattern really works couse the get lost in recurssion.
