What will you learn in Java Multithreading for Senior Engineering Interviews Course
- Fundamentals of concurrency in Java: Core concepts like threads, processes, parallel vs concurrent execution, deadlocks, critical sections, and synchronization primitives.
- Deep dive into Java threading constructs: Become proficient in
ExecutorService, thread pools, locks (ReentrantLock,StampedLock), atomics, barriers, latches, and concurrent collections. - Java Memory Model & synchronization: Understand
volatile, happens-before relationships, memory reordering, and how they impact thread safety.
- Real-world concurrency patterns: Learn classic problems like producer-consumer, dining philosophers, reader-writer, token bucket filters, and how to implement and reason about them.
- Interview-focused practice: Tackle 19+ hands-on problems modeled after FAANG-level questions to build confidence under pressure.
