Section A:
1) Current
project explanation from cv
2) Roles and
responsibilities in past projects
3) Technologies
you know
4) Spring Cyclic
dependency if class has B bean and class B has class A bean as
@Autowired
5) Spring
@Autowired annotation
6) In Spring is
@Autowired B b in class A not get autowire then what is the problem
scenarious in this and its fix
7) Abstract
versus Interface
8) Duplets like
1, -1 , 3, -3 in array, and how to find number of duplets
9) Scenario
based:- If many number of TREDS transaction are going on in threads
and each transaction giving its value money amount and to find the
total sum at any time of all previous transactions and threads
transaction are going on from moring 9AM to 3:30 PM and at any time
to evaluate total amount of all previous transactions.
write the the
linkedlist template class.
• Asked to
write your stack using array and some question on functions push and
pop and when/how will you resize it, give implementation logic.
• Problem
statement : you have a file of 1000 line, read the line of file by
using 10 thread in such a way line one read by thread 1, 2nd by
thread 2, line 3 read by thread 3............. line 10 read by thread
10 again line 11 read by thread 1........ line 20 read by thread 10
.... and so on....
1) some question
on wait , notifyAll() and synchronization and logic.
• Problem
Statement: There is one way linked list find the Nth element from
last.
Section C:
1. Static String
variable in Interface and it’s accessibility through
implementing/Extending class
2. Default method
in java
3. Final modifier
for to method of implementing class of interface and extending class
of abstract class
4. Linked list vs
Tree set
5. Hashmap-(get/put
method functionality – Collision resolution, improvements in java
8, null as key, multithreading issues with synchronized map,
comparison with Hash table, when it will behave as linklist and
performance comparison in the same case with linklist time+space
both).
6. Concurrent
Hashmap- Read/Write/Delete functionality and their parallelism in
case of multiple threads
7. Three threads
needs to execute and main method waits for their finish, Join
functionality internal working, wait internal working
8. What is
executor framework and type of pools and way of returning futures
9. Scenario:
Multiple threads are executing with one thread throwing unhandled
runtime exception, what will be returned in future
10. Design
patterns:- Singlton/ Difference between builder vs Factory
11. Joins in sql
12. Composite Key
in sql
13. referential
integrity
14. Composite key
vs Foreign key relationship
15. Algorithm/Puzzle:
Array of 10
numbers: shift by two elements
{0,1,2,3,4,5,6,7,8,9}{0,1,1,2,3,4,5,6,7}
Puzzle: Cut a
rectangular cake in two equal half without using any scale to
measure.
