Get host address information In Java we use the InetAddress class to represent the destination network address, including the host name and numeric type address information, and the InetAddress instance is immutable, and each instance always points to an address. The InetAddress class contains two subclasses, corresponding to the two version of the IP address: Copy

Php implements the shopping cart function. Take the Big Apple shopping network as an example. First, there are several simple login pages The logon page is displayed. Next we will go to the home page, and call out all the fruit information from the database. Then we will implement the function of adding to the shopping cart. Home page display Next is the Add shopping cart page Then the main shopping cart

Java provides two classes for the TCP protocol, which are used in client programming and server-side programming, respectively. Before the application begins to communicate, you need to create a connection that is initiated by the client program, and the server-side program needs to listen to the host's specific port number and wait for the client to connect. In the client we only need to use the socket instance, while the server side handles both the

Java programming example code based on three algorithm questions of quick sorting, java example Overview Quick sorting is an update of the Bubble sorting we have learned before. They all belong to the exchange sorting class and are sorted by continuous comparison and movemen

Java UDP network programming is implemented mainly through the Datagramsocket and Datagrampacket two classes, the following is an example program,The server listens on UDP 2000 ports and prints the received long type valuesThe client then gets a long value by entering it and sends it to the server Server:/**//* Coding by NYZHL *Import java.net. * ;Import java.io.

Speaking of the content in the java Network Communication Section, the beginner may feel a headache. It should be because the Socket communication will always be accompanied by IO stream operations, of course, those familiar with IO streams will think that this is a very interesting chapter, because everything is under their control, and this operation will become very handy, however, I/O is not familiar to

The first is a few simple landing pagesAfter the login page is written, you need to go to the processing page and bring up the user name and password from the database:This shows the login pageBelow to go to the main page, from the database to get all the fruit information, and then we can add to the shopping cart this functionMain Page display diagramNext is the Add Shopping cart pageThen first the shopping owner interface, as follows　　And then we get to the delete page, when the shopping cart

UDP is an unreliable protocol that establishes a socket on both ends of the communication, which does not establish a persistent communication connection and only sends data unilaterally to the other party without checking the results of the transmission.UDP protocol-based communication in Java uses the receive and send methods of the Datagramsocket class, but the message needs to be encapsulated by a specific class (Datagrampacket)The following is an

To give readers a better understanding of non-blocking I/O, this section provides a simple example that demonstrates how to apply non-blocking I/O to a network program. The reader may not have to worry about the specifics of the example first. Because the main purpose of this example is not to explain the use of non-bl
