Course Description

Thank you for checking out the Java Multithreading and Concurrency Masterclass, your comprehensive path to becoming a master of concurrent programming using Java. The course is best suited for developers who want to build scalable, high-performance, and thread-safe applications, while using the current multithreading patterns.
Module 1: In this module, you will learn key concepts about multithreading, concurrency vs parallelism, and how the Java memory model works with multithreaded situations.
Module 2: In this module, you will learn how to create and control threads using the Thread Class for general use and the Runnable interface, as well as the significant new Virtual Threads in Project Loom. You will Also, learn about the thread states, thread lifecycle, and key thread methods like start(), join(), and sleep().
Module 3: is dedicated to synchronization methods for avoiding race conditions and making threads safe. You'll use synchronized blocks, locks, and the volatile keyword, and learn about Java's happens-before guarantee in depth.
Module 4: you will learn about advanced synchronization primitives, such as wait()/notify(), Semaphores, Count Down Latch, Cyclic Barrier, as well as how to avoid deadlocks and starvation.
Module 5 discusses thread pools and the Executor framework as well as the Fork/Join framework, Scheduled Thread Pool Executor, thread reuse, and best practices for managing task execution.
Module 6 covers concurrency utilities and atomic operations. You will learn to use Concurrent HashMap, Blocking Queue, atomic variables, Compare-and-Swap(CAS), and understand false sharing and its performance implications....
Module 7: you are going to learn how to test and debug multithreaded code. You'll identify race conditions, create unit tests using JUnit/TestNG, and profile JVM performance so that your applications run efficiently.
Module 8: brings practical multithreading patterns like Producer-Consumer, the use of Thread Local variables, and design patterns like Singleton in multithreaded environments.
Module 9: focuses on parallel programming and performance optimization. You’ll implement parallel algorithms, understand Amdahl’s Law, and learn to improve memory consistency and minimize interference.
At the conclusion of this masterclass, you will have the know-how and confidence to build solid, concurrent Java applications, ace technical interviews, and make your software ready for real-world performance.

Goals

  • Java Thread lifecycle and concurrency fundamentals
  • Creating and managing threads using Thread, Runnable, and Virtual Threads (Project Loom)
