What is Java Unit testing, and how do I learn it...


Java Unit testing is when you create small tests to verify that small bits of your code are working as “units.” Typically you write these tests in Java itself. In each test, you might get the system into a certain state, then you interact with the system to exercise the behavior you want to test. You finally verify whether or not the system did what you expected.
A primary goal is to reduce the number of defects that you integrate into the rest of the source base.
You’ll find numerous tutorial articles if you search. Most people use JUnit, a simple tool that you’ll find in Eclipse or IDEA.

  2. Unit testing is the software testing technique where a group of software program components or modules are tested individually. This technique effectively helps in validating the accuracy of a section of code by considering stubs, mock objects, drivers, and unit testing frameworks.

JDK 25: The new features in Java 25

 Java Development Kit (JDK) 25, scheduled for release in September 2025, is set to introduce several significant enhancements. Here's an overview of the notable features: 1. Stable Values API (Preview): This feature introduces stable values—objects holding immutable data treated as constants by the Java Virtual Machine (JVM). By allowing greater flexibility in initialization timing compared to final fields, stable values aim to improve application startup times. They enable performance optimizations akin to constant-folding, previously exclusive to JDK code, and ensure thread-safe, single-time initialization. This decouples the creation of stable values from their initialization without significant performance penalties.  2. Removal of 32-bit x86 Port: JDK 25 plans to eliminate both the source code and build support for the 32-bit x86 port, which was deprecated in JDK 24. Maintaining this port has become less beneficial, especially with the challenges in keeping it updated wit...

what is circuit breaker in microservice

   A circuit breaker is a design pattern used in microservice architecture to improve the resilience and fault tolerance of the system. In a microservice architecture, multiple services work together to deliver a business function. When a service is not available, the downstream services depending on it may start to fail as well, leading to a cascading failure. A circuit breaker helps prevent cascading failures by monitoring the status of the dependent services. If a dependent service is not responding, the circuit breaker trips and redirects the traffic to a fallback mechanism, such as a cache or a default response. The circuit breaker periodically attempts to reconnect to the dependent service, and once it's available, it resumes directing traffic to it. The circuit breaker pattern helps prevent failures from spreading across the system, improves the availability of the overall system, and can help reduce the load on dependent services.
