How to Debug Python with Visual Studio Code (VS Code) (2026)

Video Description

How to Debug Java with Visual Studio Code (VS Code) Debugging is one of the most important skills every Java developer must learn, and Visual Studio Code (VS Code) provides powerful built-in tools that make Java debugging simple and effective. In this tutorial, you will learn how to debug Java applications using Visual Studio Code step by step. This guide is perfect for beginners, students, and developers who want to understand Java debugging in a clear and practical way. We begin by explaining what debugging is and why it is essential in Java development. Debugging helps you identify logical errors, runtime issues, and unexpected behavior in your Java programs without relying only on print statements. VS Code offers an interactive debugger that allows you to see exactly how your code executes line by line. In this video, you will learn how to prepare your environment for Java debugging in VS Code. We briefly cover the required setup, including installing the Java Development Kit (JDK) and the necessary Java extensions in Visual Studio Code. These extensions enable features like debugging, IntelliSense, code navigation, and project support. Next, we demonstrate how to open or create a Java project in VS Code and run it in debug mode. You will learn how to set breakpoints in your Java code and understand how breakpoints pause execution at specific lines so you can inspect variables and program flow. We then explain the VS Code debugging interface in detail. You will learn how to use the Debug panel, inspect variables, view the call stack, and use the Watch window to monitor expressions while your program is running. Step-by-step debugging actions such as Step Over, Step Into, Step Out, and Continue are explained clearly with practical examples. This tutorial also covers how to debug common Java issues such as null pointer exceptions, incorrect logic, and unexpected variable values. You will learn how to trace errors efficiently and understand what your program is doing at runtime. Additionally, we show how to use the Debug Console in VS Code to evaluate expressions and test code while debugging. Common beginner mistakes and troubleshooting tips are also discussed to help you avoid confusion and debug Java programs more effectively. By the end of this tutorial, you will be confident in debugging Java applications using Visual Studio Code. This skill will help you write better code, fix bugs faster, and become a more productive Java developer.
