A thread in Java is the path followed when executing a program. All Java programs have at least one thread, known as the main thread, which is created by theJava Virtual Machine(JVM) at the program’s start, when themain()method is invoked. In Java, creating a thread is accomplished b...
CompletableFuture isan extension to Java's Future APIwhich was introduced in Java. A Future is used as a reference to the result of an asynchronous computation. It provides an isDone() method to check whether the computation is done or not, and a get() method to retrieve the result of th...
Extensive: In Java development, if you want to improve system performance, thread pool is already a basic tool that more than 90% of people choose to use Uncertainty: There may be many thread pools created in the project, both IO-intensive and CPU-intensive, but the parameters of the threa...
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...

Garbage Collection is a feature of Java programming language that automatically manages memory allocation and deallocation for objects created in an eden space.
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. ...
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 ...
