Tech Interview Questions -2 1. What is the difference between fail-fast and fail-safe iterators? Answer: Fail-fast: These iterators throw a ConcurrentModificationException if the collection is modified while iterating (e.g., iterators from ArrayList, HashMap). Fail-safe: These iterators do not throw an exception if the collection is modified while iterating, as they operate on a clone of the collection (e.g., iterators from CopyOnWriteArrayList, ConcurrentHashMap). 2. How does the ConcurrentHashMap work in Java? Answer: ConcurrentHashMap is designed for concurrent access. It divides the map into segments and allows multiple threads to read and write concurrently without locking the entire map. Each segment can be locked independently, thus improving concurrency. 3. What are the main differences between Comparable and Comparator interfaces? Answer: Comparable: Used for natural ordering of objects. It has a single method compareTo(Object o) and is implemented by the class of objects to be compared. Comparator: Used for custom ordering of objects. It has a single method compare(Object o1, Object o2) and can be implemented as a separate class or anonymous class. 4. How does the TreeSet maintain order in Java? Answer: TreeSet is a NavigableSet implementation based on a TreeMap. It maintains elements in a sorted order according to their natural ordering (if the elements implement Comparable) or a specified Comparator (if provided at the set creation). 5. What is the purpose of the Collections utility class? Answer: The Collections utility class provides static methods for working with collections. It includes methods for sorting, searching, reversing, shuffling, and creating synchronized or unmodifiable collection wrappers, among others. #Canada #USA #Europe #Australia #India #Toronto #Seattle #Dubai #AbuDhabi #HR #Recruiter #IT #MNC #Hiring #Opportunity #LPU #PTU #MBA #Delhi #Gurugram #Noida #bangalore #pune #chennai #mumbai #Jobs #ITJobs #Freshers #Placements #hiring #job #vacancy

I.T. Jobs are dead for Freshers ? In the I.T. industry, there is no job for freshers. because the lost company wants an experienced candidate for their job post. Suppose we find any job postings for freshers. In that job post were already lost of experience people already apply for that job. And mainly experienced people get jobs. For company thought. If I want to hire someone according to my requirements,. I get some experience people of that Job role they have experience. Then the company will hire experienced people. Not for freshers If you have the option, will you choose freshers or experience? LinkedIn InSync Solutions #IT_Insdustry #web developer Sana A. #IT_service  

"Stop the Layoff Trend" My genuine request to all companies, Please hire freshers!! Today I am seeing lots of openings but most of them require 3+ years of experience. Every company is asking for experienced professionals only. This is a very bad trend going on in the market. Companies are thinking they need experienced professionals for positive contribution to their projects and they need to spend time in training freshers and only after they are trained for few months they will be able to contribute. This is completely false. Freshers contribute heavily in project development! Freshers bring a lot of energy into the teams. They are always curious to learn new technologies. They ask very good questions. They help seniors revise their concepts. They are the ones who work super hard because they have the energy and time. They are happily willing to spend as much time as they want in order to grow and learn. Freshers, just by doing what they are doing, helps seniors revitalize their zeal to code. They will be able to pick up new technologies very quickly and happily teach everyone what they have learnt. Hiring freshers is essential for growth of an organization. They help the companies to innovate, adapt to change and stay competitive. 🌟This post serves as an invitation to everyone. Please repost as much as possible and initiate a new chain of positivity. To all dear #recruiters: If there are any current openings in your company, please comment with the job position, years of experience (YOE), and any specific requirements. #Job_seekers, please comment down your skills and years of experience (YoE). Your participation is greatly appreciated. Let's support each other in this journey. Share your thoughts; they will be valued.

Walking into my first interview, it feels like every step is a mix of excitement, nerves, and self-doubt. 💭. There’s a thousand things running through my head – 'Did I prepare enough? What if I forget something crucial? Will they recognize my potential despite my lack of experience?' 😬 As a fresher, there's always that hint of imposter syndrome, wondering if I'm good enough compared to others. But then I remind myself: this interview isn’t just a test of knowledge; it’s a chance to show my eagerness to learn, my resilience, and my dedication 🌱💪. I might not have years of experience, but I bring with me countless hours of hard work, late-night study sessions, and the determination to grow in any way I can 📚✨. To all freshers like me: let’s keep our heads up, let our passion speak for us, and remember, this is just the beginning of our journey 🚀🌟." Fresher Jobs Fresher Jobs WebDevelopment
