What Is a Quasar Fiber? Quasar is a user-friendly library of lightweight threads for concurrent programming in Java. Quasar abstracts the fiber and thread into a single strand, allowing fibers and threads to interoperate seamlessly. Quasar fibers are implemented just like OS threads, only in JVM...
What is Java? In this article, we explore the history of Java, its key features and benefits, and real-world examples of its applications.
If we need to share state between different threads, we can create thread-safe classes by making them immutable. 如果我们需要在不同线程之间共享状态,则可以通过使它们的值不可变来创建线程安全类。 Immutability is a powerful, language-agnostic concept and it's fairly easy to achieve in Java. ...
Java 8 is a giant step forward for the Java language. Writing this book has forced me to learn a lot more about it. In Project Lambda, Java gets a new closure syntax, method-references, and default methods on interfaces. It manages to add many of the features of functional languages wit...

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 ...
