java 网络编程-端口

public class http {

public static void main(String[]args) throws UnknownHostException
{
    InetSocketAddress socketaddress=new InetSocketAddress( "127.0.0.1", 8080);
    InetSocketAddress socketaddress2=new InetSocketAddress("localhost",9000);
    System.out.println(socketaddress.getHostName());//获取本机名
    System.out.println(socketaddress2.getAddress());//获取本机地址和域名
    System.out.println(socketaddress.getPort());//得到端口名

}
}
