SCJD 同步语句与锁

[英]SCJD synchronized statement vs Lock

原文 2011-08-09 18:31:55 8 1 java

I'm trying to justify the use of synchronized statement vs Java Concurrent API for my SCJD.我试图证明我的 SCJD 使用synchronized语句与 Java 并发 API 是合理的。

So far the only reason I can give is it is more simple, easier to understand and cleaner.到目前为止，我能给出的唯一原因是它更简单、更容易理解和更清晰。

Are there any better technical reasons?有更好的技术原因吗？

1 个解决方案

The best reason is robustness.最好的理由是稳健性。

A lock must be released, and forgetting to do it, or not doing it properly (in a finally block) can have disastrous effects.一个锁必须被释放，而忘记释放它，或者没有正确地释放它（在 finally 块中）可能会产生灾难性的影响。

Since synchronized protects a whole block of code or a method, and automatically releases the lock when the block or method ends, using it is safer and leads to less programming errors.由于 synchronized 保护了整个代码块或方法，并在块或方法结束时自动释放锁，因此使用它更安全，并且导致编程错误更少。
