Java获取本机ip地址和主机名

赢咖4小编告诉大家，在 Java 中，您可以使用 InetAddress.getLocalHost() 获取当前运行 Java 应用程序的服务器的 IP 地址和获取InetAddress.getHostName()当前服务器名称的主机名。

package com.crunchify.tutorials; 
import java.net.InetAddress;
import java.net.UnknownHostException; 
/**

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();
        }
    }
}

输出：

Your current IP address : appshah-mac/192.168.0.1
Your current Hostname : appshah-mac
