in which they are sent. Then TCP is a reliable protocol. The order of packets received by the receiving end is consistent with the order of the packets on the sending side.In short, TCP is suitable for network services such as remote login (rlogin,telnet) and file Transfer (FTP). Because the size of the data that needs to be transferred is indeterminate. UDP is simpler and lighter than TCP. UDP is used to achieve higher real-time or packet loss is not important for some services. UDP packet los

I. Inheritance and polymorphism1. definition of inheritanceIn the face of an object, the subclass inherits the parent class, avoids duplicate behavior definitions, but does not use inheritance to avoid repeating defined behavior, which can cause problems with program maintenance.Program code duplication in the programming is bad signal, multiple classes of duplicate code, one of the design can be considered to improve the way, is to promote the same p

Summary:The recent enterprise online written test, found that most of the enterprise's written test platform using the game Code network (although a lot of slots), and on-line programming needs to use scanner to read the input of the program, therefore, the author on the achievements of the ancestors of scanner did a new, detailed summary. We know that Java.util.Scanner is a new feature of JAVA5, and the ma

Starting with tutorial (10), you have moved from learning the basic syntax of a single class to learning about relationships between multiple classes. In tutorial (10), we learned the relationship between class and class length, association and dependency. To maintain a 1-many-to-many relationship, in the tutorial (11), we learned the array. In addition to associ

Java Network ProgrammingNetwork programming refers to writing programs that run on multiple devices (computers) that are connected through the network.The J2SE API in the java.net package contains classes and interfaces that provide low-level communication details. You can use these classes and interfaces directly to focus on solving problems without focusing on the details of the communication.The java.net

method is to request the system for garbage collection. Whether the system is recovered immediately depends on the implementation of the garbage collection algorithm in the system and the implementation of the system.E, GetProperty methodpublic static string GetProperty (String key)The function of this method is to obtain the value corresponding to the attribute named key in the system. The property names and properties that are common in the system are shown in the following table.List of prop

Java 8 Functional InterfaceA functional interface (functional Interface) is an interface that has and has only one abstract method, but can have multiple non-abstract methods.A functional interface can be implicitly converted to a lambda expression.A functional interface can support lambda in an existing function-friendly manner.Pre-JDK 1.8 functional Interfaces: Java.lang.Runnable Java.util.concurrent.Callable Java.security.Privilege
