OOPs (Object-Oriented Programming) is a programming paradigm based on objects and classes, promoting code reusability and modularity.
Encapsulation: Bundling data and methods that operate on the data within one unit (e.g., a class).
Inheritance: Mechanism to create a new class from an existing class, inheriting attributes and methods (e.g., a 'Dog' class inheriting from an 'Animal' class).
Polymorphism: Ability to pr...
Java Streams provide a modern way to process sequences of elements, enabling functional-style operations on collections.
Stream Creation: Streams can be created from collections, arrays, or I/O channels. Example: List<String> names = Arrays.asList("Alice", "Bob"); Stream<String> stream = names.stream();
Intermediate Operations: These operations return a new stream and are lazy. Example: stream.filter(nam...
Java offers platform independence, strong community support, and robust security features, making it ideal for various applications.
Platform Independence: Java's 'Write Once, Run Anywhere' capability allows applications to run on any device with a Java Virtual Machine (JVM).
Strong Community Support: Java has a vast community, providing extensive libraries, frameworks, and resources for developers.
Robust Security F...
A TypeScript class implementing basic stack operations: push, pop, peek, and isEmpty.
Class named 'Stack' with a private array to hold stack elements.
Method 'push(item: T)': Adds an item to the top of the stack.
Method 'pop(): T | undefined': Removes and returns the top item, or undefined if empty.
Method 'peek(): T | undefined': Returns the top item without removing it, or undefined if empty.
Method 'isEmpty(): boole...
Implement a custom flat function in JavaScript to flatten nested arrays without using the built-in flat method.
Use recursion to handle nested arrays. Example: flatten([1, [2, [3]]]) returns [1, 2, 3].
Check if the current element is an array using Array.isArray().
If it is an array, recursively call the flatten function on it.
If it is not an array, push it to the result array.
Return the result array after processing...
Create a component to fetch data from an API using JavaScript and handle responses.
Use Fetch API or Axios for making HTTP requests.
Handle asynchronous operations with async/await for cleaner code.
Implement error handling to manage failed requests.
Example: const response = await fetch('https://api.example.com/data');
Use useEffect in React to call the API when the component mounts.
OAuth 2.0 is an authorization framework that allows third-party applications to obtain limited access to a user's account.
OAuth 2.0 is used for delegated authorization, allowing a user to grant access to their resources without sharing their credentials.
It uses tokens (access token, refresh token) to grant access to resources on behalf of the user.
OAuth 2.0 is widely used in APIs, social media platforms, and other...

Data Structures and Algorithms (DSA) questions assess problem-solving skills and understanding of data organization.
Understand basic data structures: arrays, linked lists, stacks, queues, trees, and graphs.
Practice common algorithms: sorting (e.g., quicksort, mergesort) and searching (e.g., binary search).
Familiarize yourself with time and space complexity analysis using Big O notation.
Solve problems on platforms ...
