今天改善了一个别人写的有dns获取IP的小代码

不足之处,各位指点.偶在学习中.............

import java.net.*;
import java.io.*;

public class _0001GetIP
{
InetAddress myIPaddress=null;
InetAddress myServer=null;
String s;
BufferedReader bin;
public static void main( String args[])
{
_0001GetIP mytool=new _0001GetIP();

System.out.println("Your host IP is: " + mytool.getMyIP());
System.out.println();
System.out.println("The Server IP is :" +mytool.getServerIP());
}

//取得LOCALHOST的IP地址
public InetAddress getMyIP() {
try
{
 myIPaddress=InetAddress.getLocalHost();
}
catch (UnknownHostException e)
{
 System.out.println("error occured");}
    return myIPaddress;
}
//取得 的IP
public InetAddress getServerIP()
{
 try
 {
  System.out.print("Enter your DNS:");
    InputStreamReader in=new InputStreamReader(System.in);
    BufferedReader bin=new BufferedReader(in);
  s=bin.readLine();
  myServer=InetAddress.getByName(s);
 }
catch (Exception e)
  {
   e.printStackTrace();
  }
return myServer;
}
}
