Black box testing focuses on input-output without internal knowledge, while white box testing examines internal code structure.
Black box testing evaluates functionality without knowing the internal workings (e.g., testing a web application by checking user inputs).
White box testing requires knowledge of the code and internal logic (e.g., unit testing specific functions in a codebase).
Black box testing is often use...
Manual testing involves human testers executing test cases, while automation testing uses tools to execute tests automatically.
Manual testing is time-consuming and requires human intervention, e.g., exploratory testing.
Automation testing is faster and more efficient for repetitive tasks, e.g., regression testing.
Manual testing is better for usability testing, where human judgment is crucial.

What people are saying about HCLTech
Threads are lightweight processes that share the same memory space, while processes are independent with their own memory allocation.
Memory Usage: Threads share the same memory space, making them more efficient in terms of memory usage compared to processes, which have separate memory.
Communication: Threads can communicate with each other more easily since they share the same memory, while processes require inter-...
A stack is a LIFO data structure, while a queue is a FIFO structure, each serving different use cases in programming.
LIFO vs FIFO: Stack follows Last In First Out (LIFO) principle, while Queue follows First In First Out (FIFO).
Stack Example: Think of a stack of plates; you add and remove plates from the top.
Queue Example: A queue is like a line at a ticket counter; the first person in line is the first to be serve...
In five years, I envision myself as a Senior Software Engineer, leading projects and mentoring junior developers.
I aim to deepen my expertise in software architecture and design patterns, similar to how I learned from senior colleagues.
I plan to take on leadership roles in projects, guiding teams through complex challenges, much like a project I led last year.
I aspire to contribute to open-source projects, enhanci...
A prime number is a natural number greater than 1 that cannot be formed by multiplying two smaller natural numbers.
Definition: A prime number is only divisible by 1 and itself. For example, 2, 3, 5, and 7 are prime numbers.
First Prime: The smallest prime number is 2, which is also the only even prime number.
Non-Prime Examples: Numbers like 4, 6, 8, and 9 are not prime because they have divisors other than 1 and th...
A palindrome is a word, phrase, or sequence that reads the same backward as forward. This code checks for palindromes.
A simple palindrome check can be done using string reversal.
Example: 'racecar' is a palindrome, while 'hello' is not.
In Python, you can use slicing: s == s[::-1].
Consider ignoring spaces and punctuation for phrases.
Copying files from blob storage to a target container in CSV format involves data extraction, transformation, and loading processes.
Data Extraction: Use Azure SDK or REST API to access and download files from the source blob storage.
Data Transformation: Convert the data into CSV format, ensuring proper formatting and handling of special characters.
Data Loading: Upload the transformed CSV files to the target contai...

Interview questions for Software Engineer position covering OOPS concepts, exception handling, SOLID principles, Java 8 features, and Streams.
Abstraction in OOPS: Hiding implementation details. Example: Abstract class Shape with method draw().
Encapsulation in OOPS: Bundling data and methods that operate on the data. Example: Class Employee with private fields and public getters/setters.
Inheritance in OOPS: Reusing code...
The interview questions cover various topics related to Spring framework, REST vs SOAP, JPA repository, Feign client, circuit breaker, and Spring Security.
Spring Boot provides a simpler and faster way to set up and run Spring applications compared to traditional Spring.
Common annotations in Spring include @Controller, @Service, @Repository, @Autowired, @Component, @RequestMapping, @GetMapping, @PostMapping, @PutMapping...

Java is a popular programming language known for its platform independence and object-oriented features.
Java is platform-independent, meaning it can run on any device with a Java Virtual Machine (JVM)
Java is object-oriented, allowing for modular and reusable code
Java is known for its robust standard library, providing a wide range of pre-built functionality
Java supports multithreading, allowing for concurrent execution...
Multithreading is the ability of a CPU to execute multiple threads concurrently, allowing for better performance and responsiveness in software applications.
Multithreading allows multiple threads to run concurrently within the same process.
Each thread has its own stack and program counter, but shares the same memory space.
Multithreading is commonly used in applications that require handling multiple tasks simultaneousl...
A collection in Java is a framework that provides an architecture to store and manipulate groups of objects.
Java Collections Framework (JCF) includes interfaces like List, Set, and Map.
List example: ArrayList<String> names = new ArrayList<>();
Set example: HashSet<Integer> numbers = new HashSet<>();
Map example: HashMap<String, Integer> ageMap = new HashMap<>();
Collections can dynamica...
