Relational DBMS stores data in tables with predefined relationships, while non-relational DBMS stores data in flexible, schema-less formats.
Relational DBMS uses structured query language (SQL) for querying data
Non-relational DBMS can store data in various formats like key-value pairs, document-based, graph databases
Relational DBMS ensures data integrity through normalization and constraints
Non-relational DBMS offers be...

Dependency Injection is a design pattern in which components are given their dependencies rather than creating them internally.
Allows for easier testing by providing mock dependencies
Promotes loose coupling between components
Improves code reusability and maintainability
Examples: Constructor injection, Setter injection, Interface injection
In Java, exceptions can be handled using try-catch blocks to catch and handle specific exceptions.
Use try-catch blocks to catch exceptions and handle them gracefully
Use multiple catch blocks to handle different types of exceptions
Use finally block to execute code regardless of whether an exception is thrown or not
Throw custom exceptions using throw keyword
map transforms each element in a stream, while flatMap transforms each element into multiple elements
map applies a function to each element in a stream and returns a new stream of the results
flatMap applies a function that returns a stream for each element in the original stream, then flattens the streams into a single stream
Example: map - stream.map(x -> x * x), flatMap - stream.flatMap(str -> Arrays.stream(str.split(
ConcurrentModificationException occurs when a collection is modified while iterating over it.
Use Iterator to iterate over the collection instead of foreach loop.
If modification is necessary, use Iterator's remove() method instead of collection's remove() method.
Consider using synchronized collections or ConcurrentHashMap to avoid ConcurrentModificationException.
Linked list is a data structure where elements are stored in nodes with pointers to the next node. Array list is a dynamic array that can grow or shrink in size.
Linked list allows for efficient insertion and deletion of elements anywhere in the list.
Array list provides fast access to elements using index, but slower insertion and deletion compared to linked list.
Example: Linked list - 1 -> 2 -> 3 -> 4 -> 5, Array list
The @Controller annotation is used for traditional MVC controllers, while @RestController is used for RESTful web services.
The @Controller annotation is used to define a class as a Spring MVC controller, which can handle HTTP requests and return a view.
The @RestController annotation is used to define a class as a controller for RESTful web services, which can handle HTTP requests and return data in JSON or XML format.

OOPS stands for Object-Oriented Programming System. It is a programming paradigm based on the concept of objects.
OOPS focuses on creating objects that contain data and methods to manipulate that data.
It allows for encapsulation, inheritance, and polymorphism.
Examples of OOPS languages include Java, C++, and Python.
Dependency Injection is a design pattern where components are given their dependencies rather than creating them internally.

Promotes loose coupling between components

Normalization in SQL is the process of organizing data in a database to reduce redundancy and improve data integrity.
Normalization involves breaking down a table into smaller tables and defining relationships between them.
It helps in reducing data redundancy by storing data in a structured manner.
There are different normal forms like 1NF, 2NF, 3NF, and BCNF that define the level of normalization.
Example: If we have a t...
