** Other ways Singleton design pattern can break :
1. Serialization : while deserializing, new object will get created. To prevent, override readResolve( ) method, and return the only instance.
2. Reflection : by getting a handle on the Class<> object, one can change the accessibility of the constructor from private to public and create object. To prevent, throw RuntimeException from constructor if instance already exists.

** Runnable is not Marker interface, it is Functional interface (only one abstract method). Marker interfaces are those that have no method, no field, used only to declare that a certain class will have a certain characteristics ( example - Cloneable, Serializable )

String vs String buffer
Final vs finally
Multiple inheritance
Diamond problem
Abstract method vs default method
Threads
Synchronise block
Private constructed
Design patterns
Singleton pattern
Factory pattern
Array list vs linked list
Hash map vs hash table
Concurrent
Comparator vs comparable

[SaurabhKumar-fozp]

in runnable case, you have to create object of thread. runnable is functional interface not marker interface . you should check equals and hash code contract as well as comparable and comparator.
it felt like L1 interview.

Few corrections to others who are watching this audio

Question i understood was how to break a Singleton pattern and not describe different ways of creating Singleton 9.28
@Autowired is different than what you explained

Spring Security authentication : how do you authenticate each and every user and how is it mapped to access token?

Arraylist vs linkedlist has 6 to 7 differences

[shubhamjadhav-mkkw]

Comparator having two methods equals and compare

[ridhamthumar]

I have also 3 years of experience and faced same questions in interview. Although this seems like L1 interview. L2 will be harder compared this.

3 yrs 15 lpa is very good. We have many people with 14, 15 years experience with less package than this. They are capable but still less paid 😢

Hi Mansi, first of all thankq because of your vidoes i could answer spring boot and clear interview 🤣 but i don't have spring boot knowledge will I be able to survive in new company

[rastemmilengephirchltechlte]

What a interview he can't failed him every answer was correct

[Prabhu__Shree_Ramji]

Let me add one more correction

We can use finally without catch block but we would have to add finally with try in that situation ❤️


Why multiple inheritance is not possible

If I made class A and Class B
Which is having same method
And I made one class C which is inherited class A and Class B then because of same method in both class the Class C would be confuse about class A and Class B which method has to be Access that's diamond problem and because of that multiple inheritance is not possible in java

We can achieve it via interface

Just a question we're you in ninja Cadre or the digital Cadre as even I have 2 years of experience in tcs but while trying to switch none of there service based company is providing more than 40 percentage of hike and my current ctc is very low can you please advise how to handle this situation as my knowledge is good so I am able to Crack the interviews but the salary negotiation part is bit difficult for me .

[shafalikataria]

It's good to help people and share your experiences and help them in getting good offers. But is it ethical to record companies interview like this? I am wondering how would HR react to this if they comes to know about this.

[anandreddy]

Fake interview, .. its just a recording

[paragchitriv]

I'm in TechM and they not provided 15 L for 3 yr experience.... it's not True 😂😂

[samidfc]

Why does TechM BGV team insisting on asking login credentials of my personal UAN and Income tax portal? Go tell your Chairman to share his credentials with me. Such pathetic mindset of this team

[driveshare]

TIAA vs Nagarro which is best? Yoe- 2.5 yrs

I got a mail today from a big MNC which headline is selection mail
And inside there this is mentioned
"Dear Candidate,

Thank you for taking the time to apply with ****(company name)  It was a pleasure getting to meet you and we think that you’d be a great fit for this role."
After that they asked me to submit document on online process
I am assuming I am selected it is right or not please let me clearify

[mdumarreza]

He told. he hase 3 years experience and you wrote in headline 2 years

[SpiritualPath]

tech mahindra giving 15LPA to 3 years exp can't believe, absolute fake/scripted.
