大佬帮忙看看哪里有问题！！！

程序代码：

import *;

public class InetAdressTest {
    public static void main(String[] args){
        InetAddress address;
        try {
            address = InetAddress.getByName("http://www.hunnu.);
            String Hostaddr1 = address.getHostAddress();
            System.out.println("主机IP:" + Hostaddr1);
            address = InetAddress.getLocalHost();
            String HostName = address.getHostName();
            String Hostaddr2 = address.getHostAddress();
            System.out.println("本地主机名:" + HostName);
            System.out.println("本地主机IP:" + Hostaddr2);
        } catch (UnknownHostException e) {
            e.printStackTrace();
        }
    }
}

public class Test {
     public static void main(String[] args) throws UnknownHostException{

         //获取指定域名ip
         InetAddress inetAddress = InetAddress.getByName("www.baidu.com");
         System.out.println(inetAddress.getHostAddress());
         //获取本机ip
         InetAddress inetAddress2 = InetAddress.getLocalHost();
         System.out.println(inetAddress2.getHostAddress());
     }

}

程序代码：

import import public class InetAdressTest {
    public static void main(String[] args){
        InetAddress address;
        try {
            address = InetAddress.getByName("www.hunnu.);
            String Hostaddr1 = address.getHostAddress();
            System.out.println("主机IP:" + Hostaddr1);
            address = InetAddress.getLocalHost();
            String HostName = address.getHostName();
            String Hostaddr2 = address.getHostAddress();
            System.out.println("本地主机名:" + HostName);
            System.out.println("本地主机IP:" + Hostaddr2);
        } catch (UnknownHostException e) {
            e.printStackTrace();
        }
    }
}

把htttp去掉就可以了
