jafly by example — branded bilingual editions

jafly by example — English and Spanish editions

The Java book now uses the jafly identity, the shared Firefly palette, the approved gradient-y wordmark, and new localized front/back covers. Chapter openers and interior headings carry the same identity; the collection name is lowercase throughout.

• English: 421-page PDF and EPUB.
• Español: PDF de 450 páginas y EPUB.
• Full-page covers, correct EPUB navigation and final back-cover reading entries.
• Technical sample code, module coordinates and public APIs remain unchanged.

Source: 008ae71ae5b51d5da9f320c3ba830dfb997cee2d.

Validation: 23 book-tooling tests; English/Spanish source-listing checks; sample Maven reactor; successful post-merge GitHub CI; PDF trim/text bounds across every page; EPUB XML/navigation checks; and visual review of covers, titles, chapter openings and interior pages. All four PDF cover images match the approved artwork exactly.

The four files below include both formats and languages. SHA256SUMS records their exact bytes.

Fixed

• Wrap ordinary fenced code blocks in PDF and EPUB, matching the named listings, so long lines remain readable.
• Use JDK 25 for the companion application gates, matching the published framework dependencies.
• Install the book-tooling test dependency and pin the renderer dependencies.
• Validate both English and Spanish listings and run the tooling tests before publishing all four download formats.

The manuscript and companion application content are unchanged from the previous edition.
