@javatechie .... 55:24 You have mentioned String is "Not thread Safe". String is Immutable & we can use it in multithreaded environment right .So my question is => Immutability doesn't Guarantee Thread Safety? Plz correct me if am wrong ....!! By the way you explained all the interview Questions very well.
Thank you for this great content. It would be great help if you can make the similar video for spring and microservices interview questions. Thank you.
It was an excellent presentation ..thanks for your effort ..can't wait to learn more from your upcoming videos on java,spring,hiberate,microservice. Please keep them coming.
I am just ready to support you other than just subscribing and liking the video. It would have been great if you had some full fledged udemy course or something like that.
Hi Sir, just a bit more elaboration on the Inherited exception handling, IF the parent method doesn't throws any exception then child can thorw only runtime exception not compile time exception. If the parent method throws broader exception like "Exception" then child can thow any kind of ecxeption, or it is not necessary to throw any exception
Coming this weekend preparing PPT is taking too much time buddy . Every day giving 2 hours to prepare PPT that's why it's taking time . Keep in touch ☺️
If method throws RuntimeException then caller method no need to catch or throws furrther, in your example as you are extedended Exception class that why we have catch or throws further, instead if we extend RuntimeException then its not needed to catch or throws
Hi basant in one of the question where you are mentioning diffrence between String, Stringbuffer and String Builder there you have pointed out String is not thread safe but String is actually thread safe correct?
Thanks buddy . It required more time to prepare PPT that's the reason I am not able to give time for this . definitely I will try to upload one end of this year
47:59 if there are two objects then why hashcode of both the objects are same String str = new String("interview"); String str1 = "interview"; System.out.println(str.hashCode()); System.out.println(str.intern().hashCode()); System.out.println(str1.hashCode());
@@Javatechie hello sir, my doubt is not around intern method. my doubt is str == str1 is coming as false mean they both are pointing to different object. but when we check their hashcode then they are coming as same. so two object with the same hashcode is not possible and if both are pointing to same object as hashcode is same then == operator should have return true so its contradicting... their hashcode should be different as str is point to the object present inside heap and str1 is pointing to the object present in SCP. both are in the heap but they are two different objects String str = new String("interview"); String str1 = "interview"; System.out.println(str == str1); //false System.out.println(str1.hashCode()); System.out.println(str.hashCode()); o/p:- false 503107969 503107969
For SCP: String str = "techie"; str = str.concat("java"); System.out.println(str); Output: techiejava However, in string pool, this is newly created. so str will point to a new reference of string in SCP?
Thanks a lot for creating such nice content , i have spent my weekend watching your videos which is really knowlegeable and engaging , i can binge watch it every weekend now 🤩
To make a class immutable, we have to clone the object before assigning it to our instance variable. Even if you return a clone or new variable when getting the instance variable, they will still have access to the list that was passed at the time of object creation. If any changes are made to that list, it will alter the content of our object. Therefore, to maintain immutability, we need to ensure that the object's internal state is not directly accessible or modifiable. Making a deep copy of the mutable objects during construction or assignment is a common approach to achieving this goal. Please correct me if I am wrong
Hi Basant bhai can you make any real time project using spring boot and microservices so that it will be very helpful for me while attending the interviews.Please please can you do that one.
Thanks of the great content with use cases. I have seen many videos but the missing part in those videos is real project use cases. Can you please also make video on how to explain project, project architecture and how to explain non-functional requirement like security, scalability on project.
Based on my understanding return will go back to the calling method and will not go back anymore.. but it seems the behavior changed during this try-catch-finally? is it only on this scenario? thanks
Sir, how to answer this question. Q- After java 8, since we have default and static methods in Interface now, so now what is the need of Abstract class? Pls help.

Yes I will do that
Thank you for this useful content!!! It would be really helpful for those who wants to brush up the Java skills.
Thanks Basant , You save us from crying in interview :)
😀😂 exactly ..👍
😂
Marker interfaces are discontinued or omitted from Java 5 onwards,
why are we still using Serializable & Cloneable interfaces?
Is it omitted ? Not sure I will check and update you
Your video and way of explain to the concept are good ..
Please upload interview questions for all topics like spring boot, Spring, Webservices, core java and collections
It was an excellent presentation ..thanks for your effort ..can't wait to learn more from your upcoming videos on java,spring,hiberate,microservice. Please keep them coming.

Udemy I didn't planned yet but will try
really useful content. i have no words to describe the way you clear all my doubts.
Thank you for the detailed explanation with examples 👍
For compiler error, you say it will cry. That sounds funny 😆
😂😂
Thank You Basant for this video. This is so much much helpful.
Hi Basant, its a nice video and useful. Please do more videos on Spring Boot, Rest API and Spring Security concepts.
Tanks Basant!! I like your teaching and please make more java tricky interview Q&A video.

Very nice concept and helpful for interview, wating for next video,thanks basnat for sharing such a good content.
Hi Basant,
Thanks for compilation and explanation with practical examples.
Minor correction At 55:42
String would be thread safe as well.
Yes buddy it's my mistake 🤠 i realise later
Hi very informative. Thanks, while comparing string, buffer,builder showing string is not thread safe.
String is thread safe
This is by far the most detailed interview Q&A series thankyou sir! for this gold content!!
Thanks but we want more situation based coding interview questions for 6 years experience
Till date best video with clear answers of all questions keep it up man thanks
Very practical explanations Basant. Keep up the good work. Would love to see FAQ's on Collection Framework as well!
Coming this weekend preparing PPT is taking too much time buddy . Every day giving 2 hours to prepare PPT that's why it's taking time . Keep in touch ☺️
@@Javatechie thanks a lot
sir, I have one request, pls make a video for interview question and answer for Microservices and springboot with Spring cloud
I will do that
Thank you so much for explaining all the concepts in a neat and clean manner.
If method throws RuntimeException then caller method no need to catch or throws furrther, in your example as you are extedended Exception class that why we have catch or throws further, instead if we extend RuntimeException then its not needed to catch or throws
Yes
Hi basant in one of the question where you are mentioning diffrence between String, Stringbuffer and String Builder there you have pointed out String is not thread safe but String is actually thread safe correct?
My bad i spell it wrong. You are correct string is thread safe .
Ur.. effort is valuable....keep posting other topics like spring boot, microservice, hibernate, cloud technology

Nice! do video on Multithreading and executor service bro
Yes will do in sequence
Good content. Please upload Multithreading and Collections interview questions too.
Yes i will
Oh, I loved the term it will cry.. haha. Especially on the throwing part from parent to child vice versa. :D
Thanks Bro for your awesome video.
Eagerly waiting for next videos on this topic.
Your SpringBoot and MicroServices videos are amazing.
Thanks buddy 😊
This was awesome👏✊👍 Please make more videos like this. Thank you

@@Javatechie please reply sir
Buddy since string it self a class so hashcode and equals method will call from object class
Really it is very much helpful, Can you please create a video experienced interview questions for multithreading ?
Best ...to the topic...❤
It’s very helpful
For SCP:
String str = "techie";
str = str.concat("java");
System.out.println(str);
Output: techiejava
However, in string pool, this is newly created. so str will point to a new reference of string in SCP?
Yes
