上述代码示例中,我们首先通过NetworkInterface.getNetworkInterfaces()方法扫描可用的WiFi网络。然后,我们选择要连接的WiFi网络,并提供必要的连接信息,如SSID(网络名称)和密码。然后,我们调用connectToWiFi()方法来建立与WiFi网络的连接,并验证连接是否成功。 序列图 下面是一个使用mermaid语法标识的序列图,展示了WiFi连接的...
Java can help reduce costs, drive innovation, & improve application services; the #1 programming language for IoT, enterprise architecture, and cloud computing.
Returns all the interfaces on this machine. TheEnumerationcontains at least one element, possibly representing a loopback interface that only supports communication between entities on this machine. NOTE: can use getNetworkInterfaces()+getInetAddresses() to obtain all IP addresses for this node ...
Socket socket=newSocket();SocketAddress remoteAddr=newInetSocketAddress("1ocalhostn",8000);// 参数endpoint指定服务器的地址,参数timeout设定的超时时间(ms)// 如果参数timeout被设为0则表示永远不会超时socket.connect(remoteAddr,60000); 以上代码用于连接到本地机器上的监听 8000 端口的服务器程序,等待连接...
publicList<InterfaceAddress> getInterfaceAddresses() 获取此网络接口的InterfaceAddresses的全部或部分列表。 如果有安全管理器,则使用每个InterfaceAddress的InetAddress调用其checkConnect方法。只有checkConnect不会抛出SecurityException的InterfaceAddresses将在List中返回。
You can access network parameters about a network interface beyond the name and IP addresses assigned to it You can discover if a network interface is “up” (that is, running) with the isUP() method. The following methods indicate the network interface type: isLoopback() indicates if the ...
soc.connect(new InetSocketAddress(address, port)); You can also useNetworkInterfaceto identify the local interface on which a multicast group is to be joined. For example: NetworkInterface nif = NetworkInterface.getByName("bge0"); MulticastSocket ms = new MulticastSocket(); ...
This class represents a Network Interface made up of a name, and a list of IP addresses assigned to this interface.C# 复制 [Android.Runtime.Register("java/net/NetworkInterface", DoNotGenerateAcw=true)] public sealed class NetworkInterface : Java.Lang.Object...
publicList<InterfaceAddress>getInterfaceAddresses() 获取此网络接口的全部或部分InterfaceAddresses所组成的列表。 如果存在安全管理器,则使用 InetAddress 对每个 InterfaceAddress 调用其checkConnect方法。只有checkConnect不抛出 SecurityException 的 InterfaceAddresses 才会在列表中返回。
