round -1
current project architecture
previous project architecture
singleton class program
At wt scenario , we will go to collections and which one u prefer and why
rest creation
comparsion vs noncomparsion algorthims
wt is container
round -2
display common elements in 2 array list
missed number in array
wt types can we pass to Switch statement
Rest annotations
uses of spring boot

2. Is it possible , jar inside jar
3. jar vs war
4. wt is the use of war

1) find 2nd highest value in arrayList without using collection
2. find 2nd highest salary
3. concurrentHashmap vs hashtable, why 2 thread safe implementations
4. internally dependency injection follwing which design pattern and how to relate to IOC
5. comparable and comparator differnce
6. internally hashmap working
7. howmany ways to hashing collision resolovetion ways
8. use of volatile keyword
9. after detached state how object become to persistent state
10. Does JVM create an object of class Main?

1) written Test
2 . exact difference between encapsulation and abstraction, where u implemented in ur project
3. interface vs abstaraction and realtime example
4. in method overriding , why method name same and why we need to do override
5. our own exception and show error to customer
6. classloader subsystems
7. dynamic binding class level or interface level
8. use of default method in interface

10. Does JVM create an object of class Main?
The answer is “No”. We have studied that the reason for main() static in Java is to make sure that the main() can be called without any instance. To justify the same, we can see that the following program compiles and runs fine.
// Not Main is abstractabstract class Main { public static void main(String args[]) { System.out.println("Hello"); }} |
Output:
Hello11. memory leaks in java
