用java获取当地ip

用java获取本地ip
通常，我们都是用以下代码来获取本地ip地址的

这段代码会输出计算机中所有设备的ip，找需要的用吧，呵呵//通过调用系统的PING命令,来获得局域网IP
BufferedReader read=new BufferedReader(new InputStreamReader(proc.getInputStream()));
String str="";
for (int i = 0; i < 7; i++) 
str=read.readLine();
if(str.length()<17 || str.indexOf("timed out")!=-1){
//map.put(ip, new Boolean(false));
}else{
InetAddress addr=InetAddress.getByName(ip);
map.put(addr.getHostName(),ip);

        }
        else {
        // Process the IP to keep the last IP (real ip of the computer on the net)
            StringTokenizer tokenizer = new StringTokenizer(ip, ",");

            // Ignore all tokens, except the last one
            for (int i = 0; i < tokenizer.countTokens() -1 ; i++) {
            tokenizer.nextElement();
            }
            
            ip = tokenizer.nextToken().trim();
            
            if (ip.equals("")) {
            ip = null;
            }
        }
        
        // If the ip is still null, we put 0.0.0.0 to avoid null values
        if (ip == null) {
        ip = "0.0.0.0";
        }
        
        return ip;
}
