One, Applicationlistener and ApplicationadapterReferring to the game life cycle of LIBGDX, you have to mention a very important interface Applicationlistener, which is located in the COM.BADLOGIC.GDX package, and the main responsibility of Applicationlistener is to create and display windows. As a function in Applicationlistener: Since Applicationlistener is an interface, then it must be to implement to us

The beans in the spring container have a distinct life cycle consisting of several specific life stages, each of which allows the outside to exert control over the bean. In spring, we describe the bean's life cycle from the scope of the bean and the series of stages it under

the thread pool ends. IsTerminating () describes the shutdown and stop two states. IsShutDown () describes the non-running state, which is shutdown/stop/terminated three states. Figure 1The API for the thread pool is as follows:Figure 2where Shutdownnow () returns a list of tasks that have entered the queue but have not yet been executed. Awaittermination describes the time it takes to wait for the thread pool to shut down, and a timeout exception will be thrown if the wait time th

determine the order in which the threads are redeployed.Java thread priority is an integer, the value range is: 1 (thread.min_priority)-Ten (Thread.max_priority)By default, each thread will be assigned a priority of norm_priority (5).A thread with a higher priority is more important to the program, and the processor resources should be allocated before a low-priority thread. However, thread precedence does not guarantee the order in which threads are executed, and is very dependent on the platf

terminated state.(02) State toggle: When the thread pool is in tidying state, after executing TERMINATED (), it will be TERMINATED by tidying.The thread pool's deny policy refers to the actions taken when a task is added to the thread pool and is rejected.When a task is added to the thread pool it is rejected, possibly because: first, the thread pool closes unexpectedly. Second, the number of tasks exceeds the maximum limit of the thread pool. thread pool consists of 4 rejection policies: ,

(1) initialization----in this phase, two main tasks are accomplished: First, initialize the settings required in the life cycle of the incoming Web request, and track view state. First, the page framework raises the Init event by default and calls the OnInit () method, which the control developer can override to provide initialization logic for the control. Thereafter, the page

JSP is the essence of the servlet, the developer's JSP file will be compiled by the Web container into the corresponding servlet, when the servlet is running in the container, the creation and destruction of its instance is not determined by the programmer, but by the Web container control. There are two opportunities to create a servlet: 1. When a client requests a servlet for the first time, the system creates an instance of the servlet, most of which are the servlet. 2.WEB application star

When the access is increased, the performance of your server is compared, and cookies should be used to mitigate server performance. 4, a single cookie can not save more than 4K of da

CORBA excitation. Although the last two features have nothing to do with the concept of object adapters, we still incorporate them into the "POA generation" definition. This means that this article has abridged the history of CORBA's extensive version of Boa and PoA's views, enabling users to focus on concepts. The following focuses on the life cycle of CORBA objects and their implementation, looking at t

first, what is the life cycle. In popular language, it is a sequence of instances in Vue or components from creation to elimination. Although not very rigorous, but also basically understandable. Through a series of practices, now put all the problems encountered, and today to record the difference between created and mounted: two, created and mounted difference. The official illustrations are as follows

) is used to convert the source file into a machine language and then run it on the virtual machine;6. The extension layer is a set of functions, class libraries, and streams that PHP uses to perform certain operations. For example, we need MySQL extension to connect to MySQL database;7. When Ze executes the program, it may be necessary to connect a number of extensions, then Ze will control to the extension, and so on after the specific tasks are processed and then returned;8. Finally, ZE retur
