Java-Concurrency

A focused collection of Java concurrency experiments, examples, and notes aimed at building intuition for safe, performant multithreaded code.

Goals

• Explore core concurrency primitives in Java
• Demonstrate common patterns and pitfalls
• Provide small, runnable examples for learning and reference
• Track performance and GC behavior where relevant

What’s Inside

• Thread creation and lifecycle
• Synchronization and visibility
• Locks and atomics
• Executors, futures, and thread pools
• Coordination utilities (latches, barriers, semaphores)
• Concurrent collections
• Performance notes and micro-benchmarks

Requirements

• Java 17+ (or a modern LTS)
• Gradle (wrapper or system Gradle)

Build

gradle build

Run

gradle run

Notes

• Examples are intentionally small and focused.
• Some classes may be used for experimentation and logging to observe GC and scheduling behavior.
