Bass in sound of attendee is sufficient enough to select him for the job😀😀😀

[@madhusudhan316]

Really that's what I'm thinking 😂

[@rahimkhan-fh9dd]

Duplicate record Select name, count(*) from employee group by name having count(*) > 1

[@praffulkshr8555]

You're are pretty good explaing. Best of luck whoever interviewed. I see high chances there.

[@pratapjavasingh3239]

Disadvantages hibernate when we are persisting the usage amount of the data they're internally convert the relationship formats so as performance wise slower then other api like spring JDBC

[@pratapjavasingh3239]

One thing is special this candidate that is teachnial based communications skills second times I'm watching his video 👍

[@pratapjavasingh3239]

1)Fixed thread pool 2)singles threads pool 3)cache thread pool

[@pratapjavasingh3239]

Factory of factory is called abstract factory

[@pratapjavasingh3239]

If u are using spring data jpa then data jpa provides u pagenable interface through the this interface we can achieve the pagination

[@kreativebundles8775]

your total experience?

[@phoneix24886]

Spring data JPA uses hibernate as default ORM and hikari as default connection pool right now.

[@pratapjavasingh3239]

Git fetch and pull so in pull we are extracting the complete project form masters branch GitHub repository but in fetch when multiple developers any thing has change in local repository then submit the project in again' in master branch git hub repository then that's place we can fetch means "pulling + merging"(changes in any thing happen in future')

[@sushilroy22]

Ok fine . Only one suggestion if u want prepare more . It's happen 2 or 3 interview.

[@pratapjavasingh3239]

Adapter design patterns when two interface not compatible wd each other's then we can use adapter design patterns supposed ur source code want to save the data inside the db but without db connection not possible so here middle db connection data source required then my application easily interact wd databases and ui

[@sathishreddydwarampudi4543]

How many days IBM guys will take to inform whether we selected or rejected..?

[@pratapjavasingh3239]

Compatible also required when u use future Api to capture the future objects then throughout the compatible u can achieved asynchronous mutithreading operation

[@sushilroy22]

25:21 time candidate said he worked on hibernate.28:27 time candidate said I didn't work in hibernate.

[@Priya1_123]

He says that he did not work on pagination in hibernate

[@sushilroy22]

Microservies explanation is very bad. Please check some tutorial and there explanation. Transaction explanation very bad

[@charu6363]

What is the solution for array question using Java 8? ( question was find the maximium occurence of a number in array)

[@AstronomyStartTrek2711]

ok suppose you have an int array.Fisrt convrt the int array to an Integer array.with Arrays.Stream(n).boxed.collectr(collectors.toList());...After you get a list stream through that list and put the duplicate integers count in value of a map(u can use collectors.counting or hashmap getorDefault method.So hasmap now has the frequency of all characters..Now take a tree map and sort by a comparator..to get values in descending order..Poll the first entry from tree map

[@shivam-sharma]

int[] nums = new int[] { 1, 2, 3, 2, 1, 5, 4, 2, 5, 5, 5 }; int max = IntStream.of(nums).boxed().collect(Collectors.groupingBy(Function.identity(), Collectors.counting())) .entrySet().stream().max(new Comparator() { @Override public int compare(Map.Entry o1, Map.Entry o2) { return (int) (o1.getValue() - o2.getValue()); } }).get().getKey(); System.out.println(max);

[@shivam-sharma]

if we have to print all the numbers with max occurrence we can do another round of groupby and use limit 1 and print it.

[@mr.uthamaputhiran9790]

Map countMap = intList.stream() .collect(Collectors.groupingBy(v->v, Collectors.counting()));

[@pratapjavasingh3239]

As compared to sequecial stream better performance we can achieve Parallel stream bcz parallel stream internally use the frok joined concept so when we extracting the value from any collection then it will break ur code multiple parts then we can got the actual value

[@bmbharathh]

What was the CTC offered?

[@rahimkhan-fh9dd]

In Spring JPA we need to create pageable object and It allows us to set limit offset sorting order.
