What we’re about
The greater Washington DC area's oldest and largest java user group, established in the mid 90's golden era of Java and going strong to this day! We focus on anything of interest to today's software developers, not just Java!
In addition to running the DCJUG, we host the annual Frontrunners conference series focusing on the interests of the DC area's software developer community. The next Frontrunners will happen on March 27, 2026 and will feature two main areas of focus, JS/Web and AI/Data.

Title: July 16: The Java Legacy Code Survival Guide: Add Features Without Fear
Thank you to BTI360 for hosting. They are providing the venue, plus food and refreshments.
Details:
How do you feel when you need to add a new feature to a legacy system with no tests, confusing naming, and tight coupling? Nervous? Anxious? What if there was a way to make it safer to work with and even enjoyable?
The key is to make the code safer to work with by adding tests, improving names, and refactoring toward OO principles like encapsulation and abstraction. Through live coding examples, you’ll see how small, simple refactorings can make adding new features easier.
By the end of this session, you’ll be able to identify common Java code smells, apply refactoring techniques to improve code design, and safely add new features to your codebases with confidence.
