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 ...
