java得到服务器的ip地址

① 如何用java获取服务器的地址呢大虾指教下呗，小女子这里谢谢喽！

import java.net.*;
public class NetTool{
InetAddress myIPaddress=null;
InetAddress myServer=null;

public static void main( String args[]){

NetTool mytool;
mytool=new NetTool();

System.out.println("Your host IP is: " + mytool.getMyIP());
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) {}
return (myIPaddress);
}
//取得 www.abc.com 的IP地址
public InetAddress getServerIP(){
try {myServer=InetAddress.getByName("www.abc.com");}
catch (UnknownHostException e) {}
return (myServer);
}

}

② java怎么通过域名获取ip地址

importjava.net.InetAddress;
importjava.net.UnknownHostException;
publicclassTestInetAddress{
InetAddressmyIpAddress=null;
InetAddress[]myServer=null;
publicstaticvoidmain(Stringargs[]){
TestInetAddressaddress=newTestInetAddress();
System.out.println("YourhostIPis:"+address.getLocalhostIP());
Stringdomain=www.jb51.net;
System.out.println("Theserverdomainnameis:"+domain);
InetAddress[]array=address.getServerIP(domain);
intcount=0;
for(inti=1;i<array.length;i++){
System.out.println("ip"+i+""+address.getServerIP(domain)[i-1]);
count++;
}
System.out.println("IPaddresstotal:"+count);
}
/**
*获得localhost的IP地址
*@return
*/
(){
try{
myIpAddress=InetAddress.getLocalHost();
}catch(UnknownHostExceptione){
e.printStackTrace();
}
return(myIpAddress);
}
/**
*获得某域名的IP地址
*@paramdomain域名
*@return
*/
publicInetAddress[]getServerIP(Stringdomain){
try{
myServer=InetAddress.getAllByName(domain);
}catch(UnknownHostExceptione){
e.printStackTrace();
}
return(myServer);
}
}

③ java 调用接口获取服务器IP和端口号

package test5;
public interface A {
void setAll(int ID,String IP);
String getAll();
}
package test5;
public class B implements A{
String IP;
int ID;
public void setAll(int ID,String IP) {
this.ID=ID;
this.IP=IP;
}
public String getAll() {
return "ID为: "+ID+"\t\t"+"IP为: "+IP;
}
public static void main(String[] args) {
B b=new B();
b.setAll(1, "192.168.1.1");
System.out.println(b.getAll());
}
}

④ java如何获取当前时间，java如何获取ip地址

publicstaticvoidmain(String[]args){

try{

System.out.println("当前时间:"+newDate());

System.out.println("IP地址:"+InetAddress.getLocalHost());

}catch(UnknownHostExceptione){

e.printStackTrace();

}

}

⑥ JAVA获取IP地址

public static void main(String[] args) { try { // 获取计算机名 String name = InetAddress.getLocalHost().getHostName(); // 获取IP地址 String ip = InetAddress.getLocalHost().getHostAddress(); System.out.println("计算机名："+name); System.out.println("IP地址："+ip); } catch (UnknownHostException e) { System.out.println("异常：" + e); e.printStackTrace(); } }
