@24:19 , The client creates adaptor by using WeightMachineAdaptor wm = new WeightMachineAdaptor(new WeightMachineImpl()). Here client is also able to give the adaptee implementation. But client should not be able to use the adaptee, right? Can you help with this?

The implementation of "FlyWeight" and "Singleton" kind of looks same. Is there a need to make "flyweight" thread safe too?

@lucygaming9726 Месяц назад

The first example of Facade pattern looks similar to the Proxy Pattern. The second example made the pattern more clear.

Hi, so in the flyweight example once we store body in map and assuming everytime i get it from the cache then memory used will be 31 * 2 = 62 kb only, right? or am i missing something here? @ConceptandCoding

@ConceptandCoding 10 месяцев назад

Right. 62KB + for any extrinsic data

@ayushgoyal773 10 месяцев назад

@@ConceptandCoding 62KB part will be allocated for each flyweight object that we are going to create. If there are only 3 variations in the intrinsic property, we will only need to create only 3 flyweight objects. Rest we will be using the same objects and just passing different params in a function.

@user-dy7ti7ku8v 10 месяцев назад

Hi I have a question, in the flyweight pattern instead of caching cant we just use a singleton object to keep the intrinsic data?

@ConceptandCoding 10 месяцев назад

umm i dont think it will work out. because then you might have to create so many singleton classes. even object with minor change, you have to create a singleton for it.

Hi Shreyansh, thanks a lot for the effort you put in making these videos, can you please make a video based on LLD creation of stock brokerage platform like Zerodha, Groww. It would be a good real-life problem to solve.

@ConceptandCoding 10 месяцев назад

Sure buddy

@SuvamSinha-ii5ul Месяц назад

In Flyweight pattern example, if the same object is returned everytime, wouldn't humanoidRobot1 and humanoidRobot2 just refers to the same object and it would just update the position rather than creation of two objects in two different positions ?

Start with LLD first buddy, HLD theory you can learn but HLD in interview come after 1 or 2 yr of experience. LLD some videos are left

@user-sb2pu7qk7j 7 месяцев назад

As part of Bridge Pattern example, Since all Fisth, Dog, Trees are implementing the same function of calling breatheImplementor.breatheProcess() why not keep this function inside LivingThings class itself?

Sir I am a very bright person with so many skills, but due to some bad decision I joined a service based company which posted me to Amazon. I go to Amazon office and work with Amazon team, but however I want to switch back to product based company, today I gave interview at Microsoft, all interviews went good but they ghosted me , I think after they knew that I am in Amazon via a service based company “epam systems” , they judged me and now they ghosted me. Is it really possible that companies like Microsoft ghost people after knowing that they are not a permanency employee rather than a contingent one . Because in the last interview I got such feeling that the interviewer judged me on it, and he didn’t wanted me on the team.
