動力節(jié)點小編告訴大家，在 Java 中，您可以使用 InetAddress.getLocalHost() 獲取當(dāng)前運行 Java 應(yīng)用程序的服務(wù)器的 IP 地址和獲取InetAddress.getHostName()當(dāng)前服務(wù)器名稱的主機(jī)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();
        }
    }
}

輸出：

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