Code analysis
Code analysis is the systematic examination of source code, compiled code, or program behavior to determine its structure, properties, behavior, or defects.
Troubleshooting Java, Second Edition
A method for examining source code and its execution to understand behavior, identify problems, or support changes.
- How it is used
- Uses investigation to understand applications, troubleshoot failures, implement capabilities, and learn unfamiliar technologies.
- How deep it goes
- Descends from method-level reading into hidden instructions while balancing detailed understanding against growing investigation complexity.
- Examples
- Examines a Java Decoder method that extracts digits from strings and sums them.
- What you can do after
- Diagnose behavioral differences by tracing execution, forming investigation questions, and choosing where to inspect more deeply.

Learn AI-Assisted Python Programming, Second Edition
Code reading is the deliberate examination of source code to understand its behavior and locate defects.
- How it is used
- Uses deliberate examination to understand program behavior and locate defects.
- How deep it goes
- Explains line-by-line tracing and overall purpose, without descending into implementation internals.
- Examples
- Uses a Scrabble best_word function and generated-code bugs that testing exposes.
- What you can do after
- Diagnose/debug with it by tracing execution and identifying a program’s purpose when generated code fails.

100 Java Mistakes and How to Avoid Them
- How it is used
- Uses static analyzers during editing, builds, and continuous integration to identify likely mistakes before they reach execution.
- How deep it goes
- Explains analyzer integration, diagnostic limits, misleading quick fixes, and scoped suppression, but not analyzer implementation internals.
- Examples
- Uses an out-of-range shift, an intentionally unread debug collection, and narrow suppression comments or annotations.
- What you can do after
- Diagnose warnings, evaluate quick fixes, integrate analyzers, and suppress intentional diagnostics without hiding future defects.

Think Like a CTO
Code analysis is the automated examination of source code for quality, correctness, compliance, or security issues.
- How it is used
- Uses automated quality checks as an acceptance gate before code advances through CI/CD.
- How deep it goes
- Explains placement and purpose in a pipeline but stops short of analyzing specific rules or findings.
- Examples
- Uses SonarQube, a develop-branch merge, and a failed pipeline gate as concrete examples.
- What you can do after
- Apply it via a CI/CD pipeline to flag quality problems before compilation, testing, or deployment.
