What You'll Learn in the Course

Common Pitfalls (How GFG Helps You Avoid Them)

1. Memory Leaks in Java – GFG articles on finalize() misuse and proper resource closure.
2. Improper Transaction Management – @Transactional pitfalls (e.g., self-invocation).
3. Overusing ORM (N+1 Query Problem) – GFG demonstrates using @EntityGraph or join fetch in HQL.
4. Starting too complex – GFG recommends the "bottom-up" approach: Core Java → Servlets → Spring → Microservices.
