I really appreciate transparency.
you both are rocking man!!...Although, its scripted but its helping us to know various interview questions...keep it going..

Str is sequence of characters to represent name address email id etc
Good one
Collections array list,hash map,linked list.
Brother please upload more videos 👍
They are making interview harder than that this is like a entry level
TQ
Nailled it bro
Amazing bro
default static and functional interfaces.
I got placed in both Cognizant and Deloitte. Thank you.
Thread goes waiting state by calling wait() or sleep () also
Yes!! Thanks Ram!!!
correct
Literal and object i think
I have worked on some spring boot projects by myself with intermediate knowledge in java, so how can i apply anywhere as a fresher???
Interface is contract.
How do you define a string in java? The answer could be:
Using primitive datatype string, and using the String Wrapper class which the guy explained how to define them.
String primitive datatype,???
String is not a primitive datatype. int, float and double are primitive data type. 👍
Pool and heap
Such basic questions are rarely asked.
Loosely coupling microservices is much more different than what you spoke
String is not a primitive datatype. Zuul is used with older Spring Boot and JDK 1.8
public interface InterfaceA {
public String abc();
}
public interface InterfaceB {
public String abc();
}
public class InterfaceABEg implements InterfaceA, InterfaceB {
I want you to write how you can use super here
}
It gives compile time error..
@@Aniketjoshi9 refer to 3.30 answer. Is his answer correct? These mock interviews are programmatically not correct and there are no cross question asked. So does the interviewer knows what he is asking?
The interface question had the default methods in it.
So if you are implementing both the interfaces and you want to access the method inside interface a, then you have to override that method inside your class. Otherwise java will give ambiguity error. The only way it will work is to override the method present in the interface.
Also the answer given by the candidate was not correct.
For freshers what is the package for springboot if we are good at spring boot? and if we done a project on springboot is it a plus point ?
For freshers, different companies have different criteria for selection. But the general idea is aptitude + programming language basics. In some companies, they ask DSA. The package generally ranges from 3-4 LPA.
That guy did it with no sweat 😳
Because it's not real interview.
bro as a fresher i know the answer of almost all questions except springboot can u suggest me some source for springboot im from mechanical final year students...
You can start watching videos of Abhilash Panigrahi or Durgesh KT ,Java Techie
Java Techie is the best source. I mastered Springboot in 2 months following him. If you look at too many resources it will just confuse and slow you. Find 1 and put all your trust in it.
Anyone explain loose coupling in 2 microservices? 21:41
Look out for async comunication between microservices
nice
Is it fir freshers interview?? We can't expect this type of questions from 3 years experience guy??
Interface is not clearly understood
Horizantal scalling explaination was wrong?
Please make videos on microservices
Yes sure. Will do!!
Scripted but Wow l learnt a lot
Edo Edo cheppu swamy...... correct but way of answer is not correct......Abstraction in Java... If you are not allow to create a object or else the class which is not complete implementation means partially implementation called abstraction......
Did he use Chat GPT on the screen? o_o
What about salary
That is discussed with hr before the technical interview.
Why abstraction is asked to everyone in every Java interview?
Abstraction is the key feature of any programming language. When we abstract the logic and just expose the input and output a lot of system complexity can be suppressed. Hope that made sense. 👍
@@cloudtech5260 definitely make sence 🔥
Waiting for him to say that he's not sure about any one of those questions 😭😳🙄
It is scripted man.
he was not able to answer correctly the question "how to deploy the application if you are scaling application horizontally"

They have posted 4 interview with same guy. They are foolingpeople
Hello,
These are mock interviews.
I1.super.print();
I2.super.print();
I dont get y are we calling interface method which has no body?
We will override it in the implementing class and call it right?
@@Raj-dy2cnInterviewer said interfaces are having default methods not abstract methods therefore he replied I1.super.print(); & I2.super.print();
@@JavaHub018 Yeah man I figured it out later, its one of those ur never gonna use scenarios
