- Q4. Explain about Polymorphism
- Ans.
Polymorphism is the ability of an object to take on many forms.
It allows objects of different classes to be treated as if they were objects of the same class.
It can be achieved through method overloading or method overriding.
Example: A shape class can have different subclasses like circle, square, etc. and all can be treated as shapes.
It helps in achieving code reusability and flexibility.
- Q5. Explain about operator overloading
- Ans.
Operator overloading allows operators to have different meanings based on the operands they work on.
It allows operators to be used with user-defined data types
It can simplify code and make it more readable
Examples include using the + operator to concatenate strings or add numbers
Operators can be overloaded for unary and binary operations
- Q6. Explain about encapsulation
- Ans.
Encapsulation is the process of hiding implementation details and providing a public interface for accessing the object.
Encapsulation helps in achieving data abstraction and information hiding.
It prevents unauthorized access to the internal state of an object.

- Q4. What is exception propagation?
- Ans.
Exception propagation is the process of passing an exception up the call stack to be handled by a higher-level method.
Exceptions are thrown when an error occurs in a method.

Each method in the call stack has the option to catch and handle the exception or propagate it further up.
If the exception reaches the top of the call s...
- Q5. Difference between get and load method in hibernate?
- Ans.
get() method returns null if the object is not found in the cache or database, while load() method throws an exception.

get() method returns the object from the database or cache while load() method returns a proxy object.
get() method is slower than load() method.
get() method is used when we are not sure if the object exists in the database or cache while...
- Q6. What is method overriding?
- Ans.
Method overriding is when a subclass provides its own implementation of a method that is already defined in its superclass.
Method overriding is used to achieve runtime polymorphism.
The method signature (name, parameters, return type) must be the same in both the superclass and subclass.
The access level of the overriding method cannot be more restrictive than the overridden method.
Example: class Dog extends Animal { pub...
- Q7. What IOC and DI in spring?
- Ans.
IOC and DI are design patterns used in Spring framework for loose coupling and dependency injection.
IOC (Inversion of Control) is a design pattern where the control of object creation and lifecycle is handed over to a container or framework.

- Ans.
HashMap is a data structure that stores key-value pairs and uses hashing to retrieve values quickly.
HashMap uses an array of buckets to store key-value pairs
Each bucket contains a linked list of entries with the same hash code
When a key-value pair is added, its hash code is used to determine the bucket and added to the linked list
When a value is retrieved, its hash code is used to find the bucket and search the linked ...
