JavaForge: Java Interview
教育
$60.00 · 專為 iPad 設計。尚未針對 macOS 驗證。
A no-nonsense Java interview prep app for backend engineers. Fully offline. Zero ads. Zero tracking.
JavaForge bundles Blind 75, System Design, Core Java, the Spring ecosystem, and behavioral questions into a pocket coach you can pull out on the train, at lunch, the night before an onsite.
WHAT YOU GET
▸ Blind 75 — 75 classic coding problems
Organized by Array / Binary / DP / Graph / Interval / Linked List / Matrix / String / Tree / Heap. Each problem ships with:
- Step-by-step approach (brute force → optimal → edge cases)
- Complete Java solution (ready to read or rewrite from memory)
- Time / Space complexity
- Gotchas that catch most candidates
▸ System Design — high-frequency designs
URL shortener, design Twitter, ride-hailing dispatch, messaging, recommendations — broken down into requirements → capacity estimation → high-level architecture → component details → trade-offs.
▸ Core Java — the three hot spots
Collections, Concurrency, the JVM. HashMap internals, ConcurrentHashMap's evolution, the Java memory model, G1 vs CMS garbage collection.
▸ Spring · Boot · Data
IoC, AOP, Spring Data JPA, Spring Security — concepts and high-frequency interview questions.
▸ Behavioral — 20 STAR-method questions
Fully editable answer templates. Pre-polish your "Tell me about a time…" stories into STAR shape so you don't freeze on the day.
