Does this skill support Java 21 features?

Yes, it includes comprehensive support for Virtual Threads and Scoped Values introduced in modern Java releases to enhance I/O-bound scalability.

Does it handle asynchronous programming patterns?

Absolutely, it provides patterns for CompletableFuture composition, including non-blocking chaining, exception handling, and orTimeout discipline.

How does it handle thread safety for shared data?

It applies best practices for immutability, safe publication, and the use of atomic variables or concurrent collections to ensure thread safety without excessive locking.

Can it help find deadlocks in my code?

Yes, the skill is designed to identify potential deadlock scenarios and suggest fixes using global lock ordering and tryLock with timeouts.

Will it improve my application's scalability?

By optimizing thread pool sizing, implementing backpressure strategies, and utilizing virtual threads, this skill directly improves system throughput.

API 开发

Implements high-performance, thread-safe Java patterns using modern java.util.concurrent utilities and Project Loom virtual threads.

This skill provides comprehensive guidance for building scalable Java applications through expert-level concurrency management and thread safety. It covers foundational thread safety using ConcurrentHashMap and Atomic types, sophisticated thread pool configuration via ExecutorService, and modern asynchronous programming with CompletableFuture. Additionally, it streamlines the adoption of Java 21+ features like Virtual Threads and Scoped Values while ensuring robust error handling, deadlock avoidance, and performance optimization through established industry patterns like Producer-Consumer and Publish-Subscribe.
