What to Look for in a Quality java-coding-problems Repository

Not every GitHub repo with "coding problems" is worth your time. Here is a checklist to evaluate a repository before downloading it as a PDF: java-coding problems pdf github

1. JDK Version: Does it use modern features (Records, Sealed Classes, Pattern Matching for switch)? Avoid repos stuck on Java 7.
2. Test Coverage: Look for a /src/test/ folder with JUnit 5 tests. This ensures the solutions actually work.
3. Explanations: The best repos don't just dump code; they explain why a HashMap is better than a TreeMap for a specific problem.
4. Active Maintenance: Check the "Last commit" date. Repos updated within the last 12 months are more likely to compile without errors.

Automated with GitHub Actions

A workflow in .github/workflows/build-pdf.yml rebuilds the PDF on every push to main and attaches it to the release.

Content Quality: Varies (4/10 to 7/10)

• The Good: Some repositories are curated gems, linking to high-quality tutorials and LeetCode solutions categorized by difficulty.
• The Bad: Many "Java Coding Problems" PDFs on GitHub are static exports from 2015. They rely on legacy code (Vector, Hashtable, pre-Java 8 date handling) which can lead you to fail modern interviews looking for current best practices.
