Introduction In Java, the manipulation and handling of time is a common requirement in programming tasks. The TimeUnit class, part of java.util.concurrent package, plays a crucial role in this aspect by providing a set of methods for converting time across different units. In this article, we delve into the TimeUnit class, its applications, and practical examples to illustrate its usefulness. Understanding TimeUnit in Java The TimeUnit class in Java provides methods for time conversions and thread-sleep operations with better readability and precision than standard approaches. TimeUnit defines the following time units: DAYS, HOURS, MICROSECONDS, MILLISECONDS, MINUTES, NANOSECONDS, and SECONDS, each ... Read More
Introduction Apache JMeter is an open-source software testing tool used primarily for load testing web applications, but its scope is not limited to web testing. It's a versatile tool that supports various types of tests, including functional, database, and more. One key feature of JMeter that ensures more realistic load testing scenarios is the use of 'Timers'. This article provides an in-depth look at Timers in JMeter and how they can enhance your performance testing. What Are JMeter Timers? In a load testing scenario, sending requests to the server without any pause can be unrealistic because real users don't continuously ... Read More
Introduction Java concurrency provides several classes and tools that allow developers to create multi-threaded applications. Among these are the ThreadPoolExecutor and Semaphore classes. The former is used to manage a pool of worker threads, while the latter can limit the number of threads accessing a certain resource at a given time. This article delves into throttling the task submission rate using these two Java classes. By understanding how to effectively manage threads and control their execution, you can significantly optimize your Java applications. Understanding ThreadPoolExecutor and Semaphore Before we jump into how to throttle the task submission rate, it's essential ... Read More
