java中获得IP地址

public class IPTest {
    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();
        }
    }
}
