Although multithreading is a powerful feature, it comes at a price. In multithreaded environments, we need to write implementations in a thread-safe way. 尽管多线程是一项强大的功能,但是是需要付出一定的代价。 在多线程环境中,我们需要有方法的去实现线程安全 This means that different threads can acces...
If we need to share state between different threads, we can create thread-safe classes by making them immutable. Immutability is a powerful, language-agnostic concept, and it’s fairly easy to achieve in Java. To put it simply, a class instance is immutable when its internal state can’t ...
ConcurrentHashMap: ConcurrentHashMap is a thread-safe version of HashMap designed for concurrent access in multithreaded environments. It provides higher performance by allowing concurrent read operations without the need for synchronization while still ensuring the consistency and integrity of the data. ...
Therefore, when I'm asked "is this code thread safe?" I always have to push back and ask "what are the exact threading scenarios you are concerned about?" and "exactly what is correct behaviour of the object in every one of those scenarios?" Communication problems arise when people with...

This means you could iterate and work with stale value, but this is the cost you need to pay for a fail-safe iterator and this feature is clearly documented Difference between Fail Safe and Fail Fast Iterator in Java In order to best understand the difference between these two iterators, yo...

Depending on the security level set in the Java Control Panel, RIAs that have an expired certificate might not be allowed to run. However, if the signature is time stamped and the time stamp shows that the certificate was valid when the RIA was signed, the RIA is allowed to run....
