when a class implements two interfaces with the same default method, Java requires you to resolve the ambiguity by overriding the method in the implementing class. like this : public class DefaultTestInterface implements I1,I2{ public static void main(String[] args) { I2 t1 = new DefaultTestInterface(); t1.print(); } @Override public void print() { I2.super.print(); } } interface I1{ default void print() { System.out.println("I1 print() called"); } } interface I2{ default void print() { System.out.println("I2 print() called"); } }
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 }
@@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.
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.
I have an interview for Senior backend engineer using springboot , java, microservices at SAIC but the link you shared for java interview preparation is not working sir. Do you have any idea for SAIC ? I appreciate your feedback
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...
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.
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......
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.
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. 👍

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..

Also the answer given by the candidate was not correct.
They are making interview harder than that this is like a entry level
Thread goes waiting state by calling wait() or sleep () also
Yes!! Thanks Ram!!!
Collections array list,hash map,linked list.
Brother please upload more videos 👍
Str is sequence of characters to represent name address email id etc
Nailled it bro

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. 👍
default static and functional interfaces.
Interface is contract.
Good one
Amazing bro

Do you have any idea for SAIC ?
I appreciate your feedback

You can start watching videos of Abhilash Panigrahi or Durgesh KT ,Java Techie

Literal and object i think
TQ
Anyone explain loose coupling in 2 microservices? 21:41
Look out for async comunication between microservices
That guy did it with no sweat 😳
Because it's not real interview.
correct
Is it fir freshers interview?? We can't expect this type of questions from 3 years experience guy??
I have worked on some spring boot projects by myself with intermediate knowledge in java, so how can i apply anywhere as a fresher???
Pool and heap
I think this is a Mock interview
Interface is not clearly understood
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......
Horizantal scalling explaination was wrong?
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.
nice
Scripted but Wow l learnt a lot
Did he use Chat GPT on the screen? o_o
Please make videos on microservices
Yes sure. Will do!!
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. 👍

What about salary
That is discussed with hr before the technical interview.
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"

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();
