The following example demonstrates how to use the getInetAddress() method of the net.Socket class to connect to a specified host:
/* author by w3cschool.cc WebPing.java */import java.net.InetAddress;import java.net.Socket;public class WebPing { public static void main(String[] args) { try { InetAddress addr; Socket sock = new Socket("www.w3cschool.cc", 80); addr = sock.getInetAddress(); System.out.println("连接到 " + addr); sock.close(); } catch (java.io.IOException e) { System.out.println("无法连接 " + args[0]); System.out.println(e); } }}
The output result of the above code is:
连接到 http:/www.w3cschool.cc/222.73.134.120
The above is the Java example - using Socket to connect to the specified host. For more related content, please pay attention to the PHP Chinese website (www.php.cn)!
