Parking Lot System Design Interview Question and Answer in Java| Object Oriented Design| Code Decode

[@karthikeyanrm3446]

I cleared an interview yesterday because of the contents in Code decode - abstraction, interface, Microservices, Hashmap working, overloading, upcasting etc. - gave answers which code decode taught for all those questions. Infinite loop thank you 🙂

[@CodeDecode]

This means a lot to us Karthikeyan. We are so glad to hear this. Well deserved Man 🎊🎊🎊🎊🎉🎉. Keep learning keep shining ⭐✨⭐✨⭐✨

[@rbrohitbisht]

This is so helpful. There is a corrections, instead of matching the "vehicle type", it should be "parking lot type" in function unParkVehicle() if(parkingSpot.getType().equals(ParkingSpotType.LARGE/COMPACT/BIKE)){.....} as a car can be parked at a Large spot and when removed, it should be removed from the Large spot. Test like this, Add car1, car2, car3, and car4 (All will be added). Not remove car1, car2, car3, or car4. For the last 2 it will show, "Car not parked here" or what you mentioned in the else block.

[@PkSam07]

Correct. I was also going to mention the same. Then saw your comment👍👍

[@ILuvBilli]

Superb explanation, I had watched many video on this topic but first time I understand this because the teaching style is very simple and basic. Best tutorial on parking lot on KZbin. Plz make on Ola, tweeter, irctc, bookmyShow also

[@CodeDecode]

Sure it's in pipeline 🙂👍thanks a lot 👍👍

[@anirbanhaldar4640]

I don't know what to say... It is simply awesome ...The way you explained..why you need this...that... that matters the most...Thank you Thank you Thank you!

[@CodeDecode]

Thanks a ton for supporting us Anirban 🙂👍

[@AllinOne-et2on]

You are coming for us..whenever we requested and providing everything. May be god also get some delay on some situations but you are't .. 🔥🔥

[@CodeDecode]

This means a lot to us 🙏🙏. All our efforts proved so worth it after seeing this comment. You actually made our day. 🙏🙏. Thanks a ton Man 🙂🙂👍👍

[@ayushdashore3747]

You have missed one case while unparking the vehicle i.e suppose the bike is parked in compact section then while unparking we need to check first that it is parked in compact parking slot or bike parking according to which we will increment the value of free compact parking spot or free bike parking spot or free truck spot.

[@rekham4583]

Greta explanation!!! its very clear and crisp. Please upload more interview related questions on system design it will be very helpful for us. Thank you!!

[@CodeDecode]

Sure Rekha. We will do that🙂👍

[@prashanttiwari120]

Excellent Video Clear and Crisp Explanation . I am sure you would have cleared all of your interviews very easily :)

[@CodeDecode]

Hehe. Thanks Prashant. We prepare others for interviews so we do it every day. its in a flow for us.

[@mahendramungamuru9500]

Superb please continue to make design patterns like this ....this way we can learn concepts in depth ...thank you so much for making such a wonderful videos 🤩🤩🤩

[@CodeDecode]

Thanks Mahendra. Sure we will continue with the same

[@vengateshm2122]

Excellent keep doing great stuff. Thanks for contributing to the community. Please improve the infographic in shorts so that it can be perceived well. A picture worth more than 100 words.

[@CodeDecode]

Sure Vengatesh, we will do that 🙂👍

[@yashaggarwal7805]

Thank you so much for your teachings.Could you please plan more sessions on some complex system design. It would help us alot .Thanks once again !!

[@CodeDecode]

Sure Yash. We will do that for sure, it's scheduled after microservices, docker and cloud playlist. Do u need anything specific that we should focus on?

[@indranilchakraborty5949]

one thing u missed is the scalability. i think we need to give scalable approach including design patterns principles. btw thank u a bunch

[@Akashsingh-kw2qo]

Hi Ma'am, your videos have been very useful to us. Please create videos on Data structures also.

[@CodeDecode]

sure akash we will create it soon

[@chhaviagarwal7514]

Hey, you are doing a great job. Your videos are helping a lot. Can you please make more videos on these low-level design questions?

[@CodeDecode]

Sure Chhavi, we will do that👍🙂

[@vinamrasangal8436]

Thanks for creating such great videos, These are very helpful

[@CodeDecode]

Thanks Sunil 🙂👍

[@dpkpk1573]

Nice explanation yes please make videos on OOD patterns....

[@CodeDecode]

Sure 🙂👍

[@hareeshjp]

explained concepts very clear, Thank you very much. Could you please create on more videos on similar system design like Cab booking for a company where employee book a seat or cancel a seat using core data structure like Map enum.. and provide REST API to get list of cabs with seating capacity and seat booking API and Seat cancel API.

[@narendrakumariitb]

Thank you 🙏 very easy to understand

[@CodeDecode]

Thanks Narendra 🙂👍

[@dinanekhai79]

Love it ! Thanks a lot

[@CodeDecode]

you're welcome

[@funforkids9927]

superb video👍

[@manaswineec3331]

Mam❤️ thankyou so much..please make more oops design programs 🤩❣️thanks a ton

[@CodeDecode]

🙂🙂👍👍sure Manaswinee

[@vinayakjondhale6701]

while unparking we need to check type of spot in which vehicle parked. If car is parked in large spot then we need to remove from large spot list and not from compact spot list.

[@sivavishnugurusamy2385]

Very Helpful

[@CodeDecode]

Thanks

[@shubhisharma3790]

Very nicely explained.....

[@CodeDecode]

Thanks Shubhi 🙂👍

[@Kumar-up2lj]

thanks you helped me

[@karthikeyanrm3446]

Is it possible to continue this system design series please .? A kind request.

[@soulfulGirl_]

Can you please share the code of this or ur git url please I dnt see it attached . Your doing amazing job kind of inspiration to all women out there 🎉❤

[@AnkitKumar-ij9sx]

Thanks for the this😀

[@CodeDecode]

Welcome 😊

[@karthikeyanrm3446]

Microservices interview questions please and then come back to Object Oriented design 👍

[@CodeDecode]

Sure Karthikeyan 🙂👍

[@sravanz1]

You might want to add class for payments and include calls related making payments when park / unpark a vehicle

[@CodeDecode]

This is a very high level design Sravan. We can do 1000s of things in this design to make it more low level design 👍👍🙂🙂

[@UTUBDZ]

Very good explanation, thanks. Would you please share your experience or resources about live Java code correction and optimization ?

[@sunilsarode152]

Thanks a lot.

[@saib3108]

Good job

[@CodeDecode]

Thanks Sai

[@chaitanyakumar7119]

Looking for a playlist of data structures and algorithms videos… Aws interview questions.. Unit testing & integration testing interview questions..

[@CodeDecode]

sure chaitanya slowly and steadily we will create videos on this topics

[@saikumarsaladi3519]

It would be helpful if there is any documentation or notes for all the topics u have covered

[@malaiarasi4400]

Hello mam, one of inter view questions.. Not sure how we can do this. If the support some data is coming via rest api which we have to get it in our database.. We use get method and do such things.. If suppose the column name in coming in data is different from column that we have in database.. How we can correlate and arrange with annotations

[@manognajoshik8465]

If you are using hibernate to persist the object data, you can specify it using @ColumnName annotation. Please let me know if I understood your question properly.

[@sankalpbarjatiya7866]

Isn’t it instead of enum we should create interfaces so that if in future suppose a new category comes up eg: electric so we make a new class for electric parking spot that is a child of vechile type interface

[@vivekbaraskar4424]

Could you please make java interview questions for 3 years and 5 years plus categories?

[@CodeDecode]

Sure Vivek we will create separate videos for this

[@chaitutom5789]

Make video on arrays and exceptions full length very deepdive and string concepts

[@CodeDecode]

Nice topics Chaitu 🙂👍. We will surely do that

[@sonalitribhuvan3409]

Do we need to code this much in LLD intrw ?

[@rishiraj2548]

🎉🎉

[@CodeDecode]

👍👍😊😊

[@shenth27]

Do we care about vehicle types here?

[@sarvinderkumar2562]

Could you pls create a system design like IRCTC ...

[@CodeDecode]

Sure Sarvinder 👍🙂

[@krishnakiran2696]

Hi Madam, I think there is a small bug in your code. In unParkVehicle method, If conditions, We need to check for vehicle.getParkingSpot().getParkingSpotType() . As we are allowing BIKES can get parked in BIKE, COMPACT and LARGE

[@yuvasmec]

Can you post video of mini application using spring boot

[@CodeDecode]

[@apoo_572]

how can you remove vehicle from the list when it has parking spots objects

[@letmeseeu]

why do you add spots into the list when parking. , but when you unpark you remove vehicles from the list instead?

[@nirjhariniparhi]

♥️♥️♥️♥️

[@nirjhariniparhi]

Really very nice explanation

[@CodeDecode]

Thanks nirjharini
