Proxy pattern: When an object does not want or cannot directly reference another object, the proxy object can act as an intermediary between the client and the target object. Static proxy is specific to implement the need for proxy object interface, overwrite the method when personalized operation. A static proxy is the implementation class for an interface that is implemented separately for the agent.Not much to say, on the code?Package com.ant;Public interface Hello {public void say ();}Packag

Dynamic proxy, as the name implies is to create a proxy object dynamically, do not need to manually create a proxy class for the proxy class, Java dynamic proxy through the proxy class and the invocation interface implementation, the code is as follows:Agent interfacePublic interface HelloWorld {public void test ();}Handlerpublic class Testhandler implements Invocationhandler {public object invoke (object proxy, Method method, object[] args) throws Th

then create the object by reflection, passing in a parameter when creating the object, that is, our own implementation of the Myinvocationhandler3. Specific operating conditionsWhen you run the proxy object's method, the virtual machine does the following:1. Collect three parameters: a reference to the proxy object, the method name of the currently calling method, the parameter of the method2. Call the Invoke method of Myinvocationhandler, parameter for the parameters collected in the previous

Python. Of course, just because a lot of developers are using a language doesn't mean they like it. Earlier this year, Stack overflow tried to understand developers ' preferences by asking developers what language they liked best. This list is dominated by new and simple languages such as Mozilla Rust, Apple's Swift,f#,scala, and go. The rise of 20,go and Swift, from obscurity to the most popular language of RedMonk surveys, is particularly striking
