Debugging is the process of identifying and resolving "bugs" (errors) in your code or design [4]. It is often the most time-consuming phase of development [4]. The Three-Step Process
Unified Modeling Language (UML) is a visual standard used to specify, visualize, and document software systems [1, 28]. is a free, open-source tool favored for its speed and minimalist interface, allowing you to create diagrams without complex menus [1, 12]. Key Features of UMLet
: Diagrams can be exported to multiple formats, including PDF, EPS, JPG, and SVG [12]. Common Diagram Types UMLet and Intro to Debugging
: Visualizes the flow of control or actions, similar to a flowchart [17, 29]. Part 2: Introduction to Debugging
: Computers are deterministic; if you give them the same input, they should produce the same output [40]. Confirm the error happens consistently before trying to fix it. Debugging is the process of identifying and resolving
: Models how objects interact over time, focusing on the order of events and method calls [17, 36].
: The most common "blueprint" showing system structure, including classes, attributes (data), and methods (actions) [16, 38]. is a free, open-source tool favored for its
