🎓 Preparing for OCPJP, OCJP, or SCJP? JavaFy is a focused Java certification companion — built for exam prep, not another "learn 10 languages at once" app.

📘 22 CHAPTERS, EXAM-STRUCTURED
The complete OCPJP-style syllabus across 8 categories — Core Java, OOP, Collections & Generics, Exceptions & Assertions, Concurrency, I/O & Files, GUI & Networking, and the Java Ecosystem. Organized the way the certification is actually structured, not just a random tutorial list.

🧠 QUIZZES FOR EVERY CATEGORY
Multiple-choice quizzes for each topic area. Track your best score per category and come back to beat it.

💻 WORKED PROGRAMS
Complete, real example programs — sorting, searching, file I/O, multithreading, exception handling, and more — so you see full working solutions, not fragments.

🗣️ INTERVIEW PREP
A dedicated set of common core-Java interview questions, for when certification prep turns into job-interview prep.

⚡ RUN CODE IN THE APP
A built-in compiler — write and run real Java code on your phone. No laptop, no IDE install, no setup.

🔥 STREAKS, BOOKMARKS & ACHIEVEMENTS
