Ever wondered what happens behind the scenes when you hit that "run" button on your Java program? The process involves a series of complex steps, from compiling and loading the code into memory to managing data in data structures like the heap and stack.
Here, we'll explore the steps of running a basic Java program, highlighting the roles of the loader, compiler, runner, and memory model. Consider a simple Java program that calculates the factorial of a number "n" using recursion.
Data deduplication is a technique used to eliminate duplicate records or rows from a dataset. Data deduplication holds significant importance in the Big Data world due to the scale and volume of data handled in Big Data environments.
Here are some key reasons why data deduplication is crucial in the context of Big Data:
In today's rapidly evolving and highly competitive tech landscape, staying ahead of the curve is essential for career growth and success. As we look ahead to 2024, certain tech skills are poised to be in high demand, driving innovation and shaping the future of various industries.
In this article, we'll explore the top 5 in-demand tech skills for 2024 and how they can propel your career forward, helping you stay relevant and get hired in the competitive job market.
Dynamic Programming (DP) is a technique used in computer science and mathematics to solve problems by breaking them down into smaller overlapping subproblems. It stores the solutions to these subproblems in a table or cache, avoiding redundant computations and significantly improving the efficiency of algorithms. Dynamic Programming follows the principle of optimality and is particularly useful for optimization problems where the goal is to find the best or optimal solution among a set of feasible solutions.
You may ask, I have been relying on recursion for such scenarios. What’s different about Dynamic Programming?
Programs usually work with data in at least two different representations:
Are you an Individual Contributor (IC) aspiring to step into a leadership role? The journey might seem daunting, but in this article, we'll explore the qualities and qualifications essential for a successful career as an engineering leader and how to actively cultivate them. Drawing from personal experiences and insights, my goal is to provide clarity on the expectations and responsibilities of an Engineering Manager (EM). Hope it will help you!
Engineering management demands a unique skill set, combining technical prowess with interpersonal abilities learned through hands-on experience. EMs orchestrate, supervise, and streamline engineering projects, teams, and operations, requiring an intricate understanding of the software engineering lifecycle and business dynamics.
In software development, concurrency refers to the ability of a system to execute multiple tasks simultaneously, enhancing efficiency and responsiveness.
There are two main mechanisms for concurrency control.
Exponential backoff is a network algorithm that gradually increases the time between successive retries when a request to a server fails. This mechanism is commonly used in distributed systems and networking protocols to handle situations where a server is temporarily unavailable or overloaded. The goal is to prevent overwhelming the server with repeated requests and to allow the system to recover from transient failures.
1. Initial Timeout: Start with an initial timeout value for the first retry attempt.
A few months ago, I penned an article discussing the debut of virtual threads in JDK 21 and their role in enabling the thread-per-request pattern. You can access the full article here.
During my interactions with the readers, I uncovered an intriguing historical tidbit: virtual threads had been introduced previously, way back in the days of JDK 1, only to be subsequently phased out.

JDK 21, released on September 19, 2023, marks a significant milestone in Java's evolution. It's a long-term support (LTS) release, ensuring stability and support from Oracle for at least eight years. In this release, Java developers are introduced to several new features, including virtual threads, record patterns, pattern matching for switch statements, the foreign function and memory API, and the ZGC garbage collector.
Among these features, virtual threads stand out as a game-changer in the world of concurrent Java applications. Virtual threads have the potential to revolutionize the way developers write and manage concurrent code. They offer exceptional benefits, making them ideal for high-throughput concurrent applications.
