What is "Java by Comparison"? (A Book Overview)
Full Title: Java by Comparison: Become a Java Craftsman in 70 Examples
Authors: Simon Harrer, Jörg Lenhard, and Linus Dietz
Publisher: The Pragmatic Programmers (2018)
Unlike traditional Java textbooks that dedicate chapters to syntax, Java by Comparison is structured entirely around before-and-after code examples. Each chapter presents a common code smell or anti-pattern ("The Old Way"), explains why it fails, and then refactors it into maintainable, professional-grade code ("The New Way").
Step 2: Create a Personal "Code Smell" Cheatsheet
As you go through the 70 examples, build a table:
| Code Smell (Old) | Better Approach (New) | Page Ref |
|----------------|----------------------|----------|
| Long parameter list | Introduce Parameter Object | 45 |
| Nested null checks | Optional flatMap | 112 |
| Catch-all exception | Specific exception types | 78 |
Step 3: Apply to Legacy Code at Work
Pick one of your company's oldest Java classes. Run a static analyzer (SpotBugs, SonarQube) and map its violations to chapters in Java by Comparison. Then submit a refactoring pull request referencing the book.
