Yeah Arpan. He prepared really well !!
Hey, can you tell what type of questions were asked to you
@@CodeDecode : one suggestion or request, if the interviewee is not able to answer then please step in to explain the answer as its a mock and many will be viewers will be wanting to know the exact answer
After watching this video, i am realized I need to learn lots of things about design patterns, need lots of interviews like this , thank you so much for uploading
We will upload more 👍👍😊

Thanks 😊
Yeah he did !!
Great Learning! Thank you Mam and Vamsi ! Please continue this series on different more interview questions.
Thank you, we will upload more videos
@12:00 I prefer the class that implements 2 interfaces having same default method , to override its own version of legs may be as 3 , though using super is also ok
Depends on the Company stacks and the Team in which we are working & then we can able to answer like this. Simple😎
Very perfect questions asked, Kudos to both!
Thanks 😊
I am having 3.5 yrs of experience as a java developer and I can say that this mock interview have all the important questions which could be asked in any interview of this level.

Hii diii ,, I'm new your subscriber ,I started to see your videos since 1 month ,and I want to say only one word,,,,,, owesome playlist 🥰 ।। Now I have took your udemy course also ,which is also adorable ,,,,, lots of love 💕,,, such a great content , and please continue the more mock interview series'।।
one possible solution to activate the profile based on env is that usually the spring boot apps are run with java -jar command, so we can configure the deployment script in such a way that based on the env for example the dev deployment script should run the command -Dspring.profiles.active=dev java -jar app.jar and similarly the qa deployment script should call the command -Dspring.profiles.active=qa java -jar app.jar. This way based on the deployment env the corresponding application properties would be picked up
True !!👍👍
Other solution is by setting the SPRING_PROFILES_ACTIVE environment variable in your production server's configuration:
export SPRING_PROFILES_ACTIVE=prod
correct me if I am wrong.
Very informative, very helpful, even for freshers, thank you.
You are most welcome
Iska knowledge dekh ke mera confidence km hogaya, I am a fresher maybe that's why🥲, but bohot kuch sikhne mila🙏
Don't feel low. He surpassed an interview expectations 🙊 he is just too good. Even if you know 70% of what he knows, then it's enough
Great interview, Got new things, Thank you
you're welcome
Just wanted to state one observation “these questions are mostly asked in big MNC small medium scale asks very antique and frustrating questions 💯
We can completely understand your frustration man. Can u please share some so that we can cover them as videos to help community ?
@@CodeDecoderecently i attended interview with global logic interviewer asked me maximum sub array question, I started solving he asked me to solve with java 8 and have to return indexes of elements as well. There were many questions he asked like this only.
One of the best interview format in youtube 👏
Thanks for the motivation
@CodeDecode Big fan of your ma'am,, your quality of content is very premium 👏
Amazing Interview and good questions asked. Couldn't resist watching full interview. The guy has real working knowledge and answered brilliantly!!
Yeah the Vamsi has prepared really well !!
Singleton by spring - object create per container , container can be multiple
Singleton by core java - object create per jvm
👍👍
Really great madam your voice is so sweet.....
😊
Just want to throw it out, your videos have been helpful whenever I decide its time to switch the company, one of my go-to channel. Also this is the first time I'm seeing you, very cute :)))

This guy is overqualified for 3 YOE! Great work!👍😜
Yeah he is 👍😊
You are doing great job👏👏👏👏
Thanks 👍
useful vedio for who are attempting for interview, vamsi done good job.
Thank you
Why we use wrapper classes.. one of the reason is our Generic type. Generic type arguments are constrained to extend Object , meaning that they are not compatible with primitive instantiations unless boxing is used, undermining performance. And most of the time we seen in collection extensive used Generics for type safety.
1.30 hr will be wasted for viewers! if i attend this interview😂 he nailed it 🎉! She shaped well❤ he rocked we shocked 😢😅
😝🤣 nicely framed !!
One more thing ,I can say that I don't know your name interviewer but seriously u r champion teacher whose cross questions are like that bombarting on the opposition.i am very happy to see this interview.
Keep going but please tell me your name 😊 interviewer
Thanks . You can call me yashi 👍
Excellent Mock Interview

Code decode ❤
My inferiority complex is on peak right now! This guy's awesome 😮
Yeah he prepared really well !!
I don't believe its 3yrs experience person answering that much well aware answers..great.
Thanks Rohit... I am a 3 years exp.. Gut
Yeah even we were shocked how well prepared he is. But trust us, this is a raw video and he is really 3 years of exp guy . Just that he prepared really well !!
Great job 👌
👍👍
You got your new subscriber ❤
👍👍
I have 2.9 yrs of experience in Java Spring Boot Microservices but didn't get interview call why?
Vamsi krishna is my college friend proud of you man👏🏻
Glad to know that. Yeah he is a gem !!
Splendid interview 👏👏
Thanks
The diamond problem occurs in programming languages that support multiple inheritance, where a class inherits from two classes that have a common ancestor. This can lead to ambiguity in the inheritance hierarchy.
,👍👍
Firstly in java 8 Metaspace came instead of PermGen.
The biggest disadvantage of PermGen is that it contains a limited size which leads to an OutOfMemoryError.
Due to the above problems, PermGen has been completely removed in Java 8. In the place of PermGen, a new feature called Meta Space has been introduced. MetaSpace grows automatically by default
👍👍
In choreography how we will handle parallel call using completable future
Please do more like this
sure we will create more like this
OMG again very nice interview.
Really start liking this channel very much. The type of interview you are taking is extremely good.
Also the candidates selection is also very very good.
Thanks for bringing very very knowledgeable interviews and content.
Thanks Abhishek ☺️👍
Hi, can you prepare video on internal working of @controlleradvice and logging(sleuth and Splunk). how interview will call and show data in Splunk. where log data will store.
Sure
ha please ek video banao
Very helpful
Thanks
Great answers 🎉
Thank you
Need advice on what do next after covering spring boot comprehensively -> microservices or go for front end ?
Depends on your interest. But for strong backend profile we need cloud and microservices
Try to do interview on microservice, Kafka, AWS and docker too. TIA
Sure
I found one correction here, in Distributed tracing traceId remains same across all the microservice and spanId is unique for each operation
Please please make security, Hibernate, Microservices and junit framework mock interview for 3 + experience
Sure
Great Questions and Great Answers, Thank you for uploading this video. Please keep posting such great videos.
Sure thanks 👍
❤
PermGen in older versions, replaced by Metaspace in newer versions
👍👍
Think the interviewer helped him to made it easier...
Please can you conduct an interview for 8 , 9 years experienced. They ask more internal questions for product based companies.
Sure Richa
Previously it was Perm gen then later Metaspace came in Java 8
@38:33 no offence but looks like people in India live and die in design patterns. I hardly use strategy pattern or observer etc, provided we use frameworks. After using streams there is significant reduction in boiler plate code, so very little scope to apply explicit design patterns ( as they are already inside framework for use)
Please make junit, Hibernate, security mock videos for 3 + years
Sure
Nice ❤
😊👍
Hi mam, please do videos on Cloud computing
Sure
Wait wasn't perm gen the older one which is replaced by metaspace... or is it vice versa I'm confused???
Yes
I have fill the form , please give me a chance to prepare myself for interview.
Could you please upload 10+/15+ experienced interviews. Thank you.
Sure Vijay 👍
trace id will same, unique and span id will change
👍👍
Name query is nothing but call by field name string name = findByName(....)
Nope as far a I know
NamedQuery annotation is attached to exactly one entity class . Something like
org.hibernate.annotations.NamedQuery(name = "DeptEmployee_findByEmployeeNumber",
query = "from DeptEmployee where employeeNumber = :employeeNo")
nice mam
👍👍
11:50 use of super keyword in interface??? can someone explain more about this please.
From Java 8, Funtional interface was introduced, so we can add Static and defaults methods with definition inside the interface rather than just abstract methods.
Also, we can achieve multiple inheritance by implementing multiple interfaces, right. So, For eg.. we have the same methods in 2 interfaces like having eat() methods. , then how do we call them to differentiate. For that, we are using Interface.super.eat(). Interfaces are unique right.. So It solves the diamond problem.
Inside the method implementation we call the interface implementation which we want to use like
Interface.super.methordName()
Hi,I watched lot of Java interviews videos in TH-cam . I never see such a knowledge person in my life with 3 year in software industry he gain all most 10 years knowledge . I know some of friends with 8,9 years experience they don’t have this much knowledge . I am Fida for your knowledge 🫡 Vamsi Krishna.
Thanks Ganesh 👍
@@refreshjavabysaikaruturiI am trying to connect you in social media.. but I couldn’t find you ..
❤️❤️👍👍
Great knowledge sir🎉
True that !! He is an asset to a team !!
maam, could you plz provide resume formate for above 2 year experience
Can you make video with .Net as well??
Java 22 is out there. Please update the interview pattern.
Can we switch from service based to product based/startups after 2.5 years of exp in service based MNC as Java developer plz help. I need guidance
Yes you can switch
Just prepare for data structure and system design along with Java microservice spring boot etc
And you're good to go
@@CodeDecodeit is over expectation for the 2.5 years experience candidate to know system design.
Is it mandatory to have knowledge of junit and mockito for 2 years experienced java developer?
Yeah because that's how you test your code and if you write code you should know how to test it
Can u send tricky question pdf?
Permgen to metaspace from java7 to java 8
👍
I am just curious to know the company name of the candidate.. getting chance to work on such organised project is rare now.
Sorry Tarang. We have to keep few things confidential else that can back fire on our candidates 🙊🙊 no company, cleint info is leaked during these shoots
Can you ease share sample resume of 3+ years experience java spring boot developer ,Thank you
Subscribed !!!
Sure 👍👍
What is its package
isko dekh k aesa lagrha hai meko kuch nhi aata java me😶🌫😶🌫😶🌫
No it's just that he is too good 👍
Can we get the transcripts?
Team wil try to fetch one. Mean while if you know how to extract that, let us know
Is microservices mandatory for 3+ years experienced?
Mam please make sure voice, none of any sentence we can hear clearly in mid or last it skipped I don't know it is for me or all but please speak sentence clearly
Please Java developer fresher video
Sure we will create soon
Am i dumb or is he that good with just 3 years exp
He is that good 😊👍
In what range of package can we expect for this level of knowledge..?
Depends on how many offers you hold😝😝
nicely played@@CodeDecode
Please make video for 2year+ experience
Sure Hitesh 👍
Mera confidence level down hogya ye dekh kar😮😮
