Module 12: Concurrency

In this module, we'll explore Java's concurrency model and compare it with JavaScript's asynchronous programming patterns. We'll learn about threads, synchronization, concurrent collections, and modern concurrency utilities.

Learning Objectives

By the end of this module, you will be able to:

• Understand Java's threading model and concurrency concepts
• Compare Java threads with JavaScript async patterns
• Implement thread-safe code using synchronization
• Use concurrent collections and utilities
• Apply modern concurrency patterns
• Understand thread lifecycle and management

Threading Basics

1. Thread Creation and Management

Java provides native threading support, while JavaScript uses event loop and async patterns.

2. Synchronization and Thread Safety

Java provides various synchronization mechanisms, while JavaScript relies on single-threaded execution.

Exercises

Exercise 1: Thread Creation and Management

Exercise 2: Synchronization and Thread Safety

Summary

In this module, we explored Java's concurrency model and compared it with JavaScript's async patterns:

Key Points:

1. Thread Creation: Java provides native threading support
2. Synchronization: Various mechanisms for thread safety
3. Concurrent Collections: Thread-safe data structures
4. Modern Concurrency: CompletableFuture and ExecutorService
5. Thread Lifecycle: Understanding thread states and management

Next Steps:

• Practice thread creation and management
• Master synchronization mechanisms
• Explore concurrent collections
• Prepare for the next module on Spring framework

Additional Resources

• Java Concurrency
