Eliminate anti-patterns: magic numbers, code duplication, and code quality issues

[Copilot]

Static analysis identified multiple anti-patterns affecting code maintainability and readability across test and source files.

Changes

Magic numbers → Named constants

• Test files: Replaced 12 hardcoded numeric literals with descriptive constants
  • BoardTest: 3 → MAX_WIDTH/MAX_HEIGHT
  • PlayerTest: 10, 20, 30 → TEST_POINTS_FIRST/TEST_POINTS_SECOND/EXPECTED_TOTAL_SCORE
  • GhostColorTest, DirectionTest, PelletTest, GhostCollisionTest: Similar replacements

Code duplication → Shared constant

• Ghost subclasses (Blinky, Pinky, Inky, Clyde) all defined identical INTERVAL_VARIATION = 50
• Extracted to base Ghost class as DEFAULT_INTERVAL_VARIATION

// Before: Duplicated in each ghost class
private static final int INTERVAL_VARIATION = 50;
super(spriteMap, MOVE_INTERVAL, INTERVAL_VARIATION);

// After: Shared in base class
protected static final int DEFAULT_INTERVAL_VARIATION = 50;
super(spriteMap, MOVE_INTERVAL, DEFAULT_INTERVAL_VARIATION);

Method length violation

• GhostCollisionTest.setUp(): 32 lines → Extracted createTestBoard(), createGhostList(), createStartSquaresList()

Code quality

• Removed commented dead code in Level.java
• Fixed indentation and trailing whitespace

Result

Checkstyle violations: 12 → 0

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• www.puppycrawl.com
  • Triggering command: /opt/hostedtoolcache/CodeQL/2.23.1/x64/codeql/tools/linux64/java/bin/java -jar /opt/hostedtoolcache/CodeQL/2.23.1/x64/codeql/xml/tools/xml-extractor.jar --fileList=/home/REDACTED/work/jpacman-framework-test/.codeql-scratch/dbs/java/working/files-to-index6976283046090517522.list --sourceArchiveDir=/home/REDACTED/work/jpacman-framework-test/.codeql-scratch/dbs/java/src --outputDir=/home/REDACTED/work/jpacman-framework-test/.codeql-scratch/dbs/java/trap/java (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
