What you'll learn
Debug Java 25 applications confidently in IntelliJ IDEA using breakpoints, stepping, watches, and call stack inspection.
Diagnose and fix bugs faster by inspecting variables, collections, and objects, and modifying state at runtime while debugging.
Use advanced debugger features like conditional and logging breakpoints, exception breakpoints, and Evaluate Expression.
Design, test, and troubleshoot complex regular expressions in IntelliJ using Check RegExp and debugger‑driven regex experiments.
Requirements
Basic Java knowledge (variables, methods, classes) and ability to run simple Java programs.
IntelliJ IDEA (Community or Ultimate) installed on Windows, macOS, or Linux.
JDK 25 (or Java 21 +) installed and configured in IntelliJ IDEA.
Very basic Maven familiarity is helpful but not strictly required.
Description
Master debugging in modern Java using IntelliJ IDEA with a fully hands‑on, project‑driven approach. This course shows how to use the debugger as a daily development tool, not just as a last resort when something breaks. Every concept is demonstrated directly in code, so you can follow along step by step.Learn to Use IntelliJ's Debugger with ConfidenceSet, configure, and manage line and exception breakpointsStep through code execution to really understand what your program doesInspect variables, call stack, and threads to find the real cause of bugsUse Evaluate Expression and Watches to test fixes without changing source codeWork effectively with lambdas, streams, and modern Java features during debuggingApply debugger techniques to real‑world Java 25 + Maven examplesUse IntelliJ's built‑in regex tools and debugger together to design, test, and fix complex regular expressions directly in your Java codeYou'll start with the fundamentals of running Java applications in debug mode and setting your first breakpoints. From there, you will progressively move to more advanced topics, including conditional breakpoints, logging breakpoints, exception breakpoints, and non‑suspending breakpoints. Practical examples show how to combine step‑over, step‑into, and step‑out actions to quickly navigate even complex code paths.​A full section is dedicated to understanding IntelliJ's debug tool window: threads view, frames, variables, watches, and inline debugger hints. You'll see how to inspect collections and objects, change variable values at runtime, and use Evaluate Expression to experiment with fixes before touching your source files.Modern Java features are covered using Java 25 examples built with Maven. You'll debug code that uses streams, lambdas, pattern matching, and other language features that can be tricky to step through if you don't know the right IDE tools. The course focuses on realistic debugging scenarios rather than toy examples, so you learn techniques you can apply immediately in your own projects.How You Will LearnThe course is structured as a sequence of short, focused lessons, each built around a specific debugging scenario. You'll see the problem first, then watch how to diagnose and fix it using IntelliJ. All sample projects are provided as Maven modules targeting Java 25, so you can clone the repository, open it in IntelliJ, and reproduce everything on your own machine.​You will also get practical tips on keyboard shortcuts, debugger settings, and productivity tricks that make debugging feel natural in your daily workflow. By the end of the course, you will not only know which buttons to press, but also how to think systematically when tracking down bugs in Java applications.​If you want to move beyond System.out.println() and start using IntelliJ's debugger as a powerful ally in your development process, this course is designed for you—whether you're just starting with Java or already working as a professional developer.
This course is for Java developers and QA engineers who want to use the IntelliJ debugger effectively in real projects.,It's ideal for junior and mid‑level developers, automation testers, and anyone working with Java 21+ and Maven who wants a practical, hands‑on guide to debugging effectively.
