class loader bootstrap classloader trying to load, If not loaded, the task is forwarded to the extension ClassLoader attempt to load, if not loaded, then to the app ClassLoader to load, if it is not loaded, then return to the initiator of the delegate, It loads the class into a URL such as a specified file system or network. If none of them are loaded into this class, the ClassNotFoundException exception is thrown. Otherwise, the found class generates a class definition, loads it into memory, a

The front-end time because of the soft examination reason, has already begun the J2SE study, the horse soldier teacher takes us into the Java world. Recently in the process of learning the Java EE, learn about the 13 core technologies, so first to a macro understanding of it.In fact, the general direction of Java is th

Java has become a large and complex technology platform, for developers, to better grasp the Java technology, in-depth understanding of the underlying technical processing details is essential. Now let's introduce the four core concepts of Java: 1.Java Virtual Machine The

each thread will share the program's memory Space (code snippets, data segments, heap space) and process-level resources (such as open files), but each thread has its own stack space.At the operating system level, the process is the basic unit of the program's operation, and in a process there are often multiple threads that do not interfere with each other concurrently. So why use multithreading?The advantages of using multithreading are:1. Using multithreading can reduce the response time of

, but have Bo not anxious to want to "Java multithreaded programming core technology" recommended to you.The specific content of the book is not listed, the Ape friends after downloading the reading will know.Read suggestions:(1) Like deep Java virtual machine This kind of book, may need to read three times to understand the knowledge point basically. "

bloggers only read the first two chapters, but they are no longer eager to recommend the Java multi-thread programming core technology to everyone. The specific content of the book is not detailed. You can read it after downloading it. Read suggestions: (1) books such as deep-dive into Java virtual machines may need to be read three times before they can basi

Multi-line threads for other Java knowledge points, there is a certain threshold for learning, and it is more difficult to understand. In peacetime work if improper use will appear data confusion, inefficient execution (as a single-threaded to run) or deadlock program hangs and so on, so mastering the understanding of multithreading is critical.From the beginning of the basic concept to the final concurrency model, this paper explains the knowledge of
