Breaking down a large application into smaller, independently deployable services can seem like a big shift in the way software is designed. When I began working with microservice architectures, the main challenge was figuring out how to structure the services so they could communicate effectively, stay maintainable, and scale independently. This is where Microservices with…
Boilerplate code has always been one of those aspects of Java development that slows me down. While Java is a powerful and widely used language, it often requires a significant amount of repetitive code just to get simple things working. Writing getters, setters, constructors, toString() methods, equals() and hashCode() implementations can take up dozens of…
Real-time communication has become a vital part of modern applications. Whether I am working on a live chat platform, a multiplayer game, a collaborative document editor, or a real-time dashboard, I often need a way to send and receive messages instantly without constant page reloads or inefficient polling. Java WebSocket Programming provides a reliable and…
Efficient logging is one of the most important aspects of building reliable Java applications. Without a good logging strategy, tracking bugs, analyzing system behavior, and diagnosing production issues becomes incredibly difficult. In my experience, a robust logging setup can save countless hours that would otherwise be spent trying to reproduce issues blindly. Among the various…
Working with databases is one of the most common tasks in software development, and MySQL has long been a popular choice due to its reliability, performance, and open-source nature. As a Java developer, I’ve often had to integrate Java applications with MySQL to store, retrieve, and manage data. Connecting Java applications to MySQL databases is…
In the evolving landscape of software development, REST APIs have emerged as a cornerstone for enabling communication between different systems and applications. Java, a widely adopted programming language, combined with the Spring Boot framework, offers an efficient and streamlined approach for building robust REST APIs. This article explores the process, tools, and best practices for…
JSON (JavaScript Object Notation) has become the de facto standard for data exchange between applications. Its human-readable syntax and lightweight structure make it an ideal choice for APIs, configuration files, and data serialization. In Java, two of the most popular libraries for handling JSON are Jackson and Gson. Both offer powerful capabilities for parsing, generating,…
Apache Kafka has grown into one of the most widely adopted platforms for building real-time streaming and messaging applications. Originally developed at LinkedIn, Kafka is now a top-level Apache Software Foundation project, known for its scalability, durability, and fault-tolerant event streaming capabilities. For Java developers, Kafka offers a rich API that integrates naturally with the…
Jakarta EE, short for Jakarta Enterprise Edition, is the modern evolution of Java EE (Java Platform, Enterprise Edition). It is a powerful, standardized platform for building large-scale, distributed, and enterprise-level applications in Java. Managed by the Eclipse Foundation since Oracle donated Java EE in 2017, Jakarta EE provides a robust set of APIs and tools…
Unit testing plays an essential role in producing reliable, maintainable, and bug-free software. It allows developers to verify that individual components of their applications work as intended, reducing the likelihood of issues in production. In the Java ecosystem, JUnit has been the de facto standard for unit testing for over two decades. With the release…
