问题描述

how to give ip address as a input on java...if i give ip addrees as a input need to display present in the server or not 

我尝试了什么：

What I have tried:

public class CrunchifyGetIPHostname {
 
    public static void main(String[] args) {
 
        InetAddress ip;
        String hostname;
        try {
            ip = InetAddress.getLocalHost();
            hostname = ip.getHostName();
            System.out.println("Your current IP address : " + ip);
            System.out.println("Your current Hostname : " + hostname);
 
        } catch (UnknownHostException e) {
 
            e.printStackTrace();
        }
    }
}

推荐答案

目前还不是很清楚你最终想做什么但 InetAddress（Java Platform SE 7） [ ^ ]类提供所有必要的功能。



未经测试的例子：

It is not quite clear what you finally want to do but the InetAddress (Java Platform SE 7 )[^] class provides all necessary functions.

Untested example:

// Input: 
//  strIp containing an IP address or a machine name
//  strServer containing a machine name

// Get the IP address to look for as InetAddress
InetAddress ip = InetAddress.GetByName(strIp);
// Get all IP adresses associated with strServer
InetAddress[] serverIps = InetAddress.getAllByName(strServer);
for (int i = 0; i < serverIps.length; i++)
{
    if (ip.equals(serverIps[i]))
    {
        // Is an IP address of the server
    }
}
