Java Core Programming Volume 1: Fundamentals

Now that we are in the 21st century, it is hard to imagine that Java-related books are so scarce, but this is just the case with Java. All the Java-related books were basically published by several Sun engineers, such as the "Hooked on Java" written by Arthur Van Hoff and "The

execution path; the so-called execution path refers to the directory list where the operating system searches for a local executable file.The same level directory in Jdk\bin contains the file, which is the source code for all public classesGet more source code (compilers, virtual machines, local methods, and private helper classes, etc.) with access to: is the anatomy of the JDK section:The difference between the JDK and the JRE can be seen clearly:There are three types

each other.Synchronization queueA synchronization queue is a mechanism for pairing producers with consumer threads. When a thread calls the Put method of synchronousqueue, it blocks until another thread calls the Take method, and vice versa. Unlike Exchanger's case, data travels only in one direction, from producers to consumers. Even though the Synchronousqueue class implements the Blockingqueue interface, conceptually it is still not a queue. It does not contain any elements, and its size met

called and passed to it with the methods object and the original invocation parameters. The calling processor must give a way to call processing.To create a proxy object, you need to use the Newproxyinstance method of the proxy class, which has three parameters:1: Class loader. As part of the Java security model, for system classes and from other classes, you can use a different classloader, currently using the default class loader with null notation

, it can be embedded, based on the class set that is currently loaded. If necessary, you can also undo the optimization.Multithreading : Multithreading brings better interactive response and real-time behavior. Multithreaded compilation is simple.Dynamic : Dynamic is important when some code is added to a running program. The current version of Java allows programmers to know the structure and behavior of objects. It is useful for systems that must pa

Iterators are often referred to as "lightweight" objects because they are less expensive to create.The iterator functionality in Java is relatively simple and can only be moved one way:(1) Use Method iterator () "Call
