125-java-concurrency

What problem does it solve?

Java concurrency can be tricky, risking data races and poor scalability; this skill provides a guided set of best practices to build thread-safe, high-performing concurrent code.

Core Features & Use Cases

• Thread-safety fundamentals with java.util.concurrent primitives and immutability.
• Efficient task coordination using ExecutorService configurations and bounded queues.
• Patterns like Producer-Consumer and asynchronous workflows with CompletableFuture, plus modern features like virtual threads and structured concurrency.
• Observability, cancellation discipline, and safe publication.

Quick Start

Run a simple Producer-Consumer example using a bounded BlockingQueue to illustrate safe task handoff between producers and consumers.
