OOP stands for Object-Oriented Programming, a programming paradigm based on the concept of objects.
OOP focuses on creating objects that contain data and methods to manipulate that data.
Encapsulation, inheritance, and polymorphism are key principles of OOP.
Examples of OOP languages include Java, C++, and Python.
Polymorphism in Java refers to the ability of a method to do different things based on the object it is acting upon.
Types of polymorphism in Java include method overloading and method overriding.
Method overloading is when multiple methods have the same name but different parameters.
Method overriding is when a subclass provides a specific implementation of a method that is already defined in its superclass.
Threads in Java allow multiple tasks to run concurrently within a single program.
Threads are lightweight sub-processes that share the same memory space.
They are used to improve performance by allowing tasks to run simultaneously.
Examples include creating a new thread using the Thread class or implementing the Runnable interface.
Spring profile is a way to segregate parts of your application configuration and make it only available in certain environments.
Spring profiles allow you to define different configurations for different environments such as development, testing, and production.
You can use @Profile annotation to specify which beans should be loaded based on the active profile.
Profiles can be activated in various ways such as through app...
Annotations used in Spring Security to apply authorization rules before and after a method is called.
Used in Spring Security to define authorization rules

OOPs concept in Java includes keywords and access specifiers for defining classes and objects.
OOPs concept focuses on objects and classes for code organization
Keywords like 'class', 'extends', 'implements' are used for defining classes and inheritance
Access specifiers like 'public', 'private', 'protected' control visibility of class members
ArrayList is implemented using a dynamic array while LinkedList is implemented using a doubly linked list.
ArrayList provides fast random access and slower insertion/deletion, while LinkedList provides fast insertion/deletion and slower random access.
ArrayList uses more memory as it needs to allocate a fixed-size array, while LinkedList uses more memory for storing references to the next and previous elements.
Example: A...
Set is a collection of unique elements with no specific order, while list is a collection of elements with a specific order and allows duplicates.
Set does not allow duplicate elements, while list allows duplicates.
Set does not maintain insertion order, while list maintains insertion order.
Examples: HashSet is a set implementation, ArrayList is a list implementation.
Reverse a palindrome string using Java
Create a function to check if a string is a palindrome
If the string is a palindrome, reverse it using a StringBuilder

To create a REST API, you need to define endpoints, implement CRUD operations, handle HTTP methods, and use frameworks like Spring Boot.
Define endpoints for different resources (e.g. /users, /products)
Implement CRUD operations (Create, Read, Update, Delete) for each endpoint
Handle HTTP methods like GET, POST, PUT, DELETE
Use frameworks like Spring Boot to simplify API development
Lambda functions in Java 8 allow for concise and functional programming style.
Use the lambda operator '->' to define the lambda function.
Specify the parameters and the body of the lambda function.
Example: (int a, int b) -> a + b

HashSet is a collection that does not allow duplicate elements and does not guarantee the order of elements.
HashSet uses a hash table for storage.
Elements are stored based on their hash code.
Adding an element to a HashSet returns false if the element is already present.

Solid design principles are a set of best practices for designing software that is maintainable, scalable, and flexible.

Liskov Substitution Principle - objects of a superclass should be replaceable with objects of its subclasses without affecting the pro...
Authentication verifies the identity of a user, while authorization determines what actions they are allowed to perform.
Authentication is the process of verifying the identity of a user, typically through credentials like username and password.
Authorization determines what actions a user is allowed to perform after they have been authenticated.
