more important. Most Internet games, such as Diablo, use UDP protocol communication, because the speed of network communication is the decisive factor of the smooth game. You can also think of a timekeeping server, if a message is lost, then really do not have to excessive tension. In addition, some applications may be able to send a UDP message back to the server for later recovery. If there is no response at the right time, the message is lost.Java

difference between the inheritance and interface, the book is very vivid examples, fish can swim, sharks are fish, clown fish is fish, so they are inheritance relationship, but people can swim, but people and fish there is no inheritance relationship, but the human and fish between the connection can be expressed by the interface. While this is understood, I cannot relate to how much of a difference these two definitions can have in a particular program. In short, to continue to learn or to fil

interface 1、接口定义行为： 对于“定义行为”，可以使用interace关键字定义。 类要操作接口，必须使用implements关键字。 操作某接口时，对接口中定义的方法有两种处理方式，一是操作接口中定义的方法，二是再度将该方法表示为 abstract。 2、行为的多态： 只要是操作同一个接口的对象，都可以使用同一方法（行为）。 3、解决需求变化： 在java中，类可以操作两个以上的类，也就是拥有两种以上的行为。 在java中，接口可以继承自另一个接口，也就是继承父接口行为，再在子接口中额外定义行为。7.2 Interface Syntax Details 1、接口的默认： 接口中的方法没有操作时，一定得是公开并且抽象。 2、匿名内部类： 临时继承某个类或操作某个接口并建立实例，由于只使用一次，不需要为这些类定义名称，这时可以用匿名内部 类（Anonymous Inner Class）。 3、使用
