以下实例演示了如何使用 net.Socket 类的 getInetAddress() 方法来连接到指定主机:
/* author by itshubao.com 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.itshubao.com", 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); } } }
以上代码运行输出结果为:
连接到 http:/www.itshubao.com/120.25.193.95
