Hand hands coincide several times on the surface there are 60 of small lattice, each Georg represents one minute, the hand hour walks 1/12 small lattice, the minute hand walks 1 compartments every minute, from the first coincidence to the second coincidence the minute hand is more than the hand hour to walk a circle namely 60 small lattice, therefore 60/(1-1

declare the runtime constant. 20. What are the similarities and differences between UDP and TCP connections? A: TCP is a transmission control protocol that provides connection-oriented and reliable byte stream services. When users and servers exchange data with each other, data can be transmitted only after a TCP connection is established before data interaction. TCP provides the time-out redial function to verify data. UDP is a User Datagram Protocol, a simple datagram-oriented transmissio

The controller provides an access to the application's behavior, which is typically implemented through the service interface. The controller parses the user input and translates it into a model that is presented to the user by the view. Spring implements a control layer in a very abstract way, allowing the user to create multiple-purpose controllers.@Controller AnnotationsThis note indicates th

instantiate an object as an XML document, and then instantiate it in reverse order. In. NET WebService, XML is also used to hold generic formats, such as WSDL and SOAP, which are XML-based. At the same time, the XAML front-end presentation language in WPF and Serverlight is also XML-based. Of course, XML can be combined with XSL to realize the performance of the foreground interface, but it cannot be done by itself.13, Microsoft's new technology and its application?The new template engine razor

the Java 5 annotation.Spring's MVC Framework64. What is the Spring MVC framework?Spring provides a full-featured MVC framework for building Web applications. The spring framework can be easily fused with other MVC frameworks (such as struts), which uses the inversion of control (IOC) to separate the controller logic from the business object. It also allows the request parameters to be bound declaratively on the business object.65.DispatcherServletThe Spring MVC Framework is designed around Disp
