import java.net.InetAddress;import java.text.SimpleDateFormat;import java.util.Date; public class test{ public static void main(String[] args) throws Exception{ InetAddress addr = InetAddress.getLocalHost(); String address=addr.getHostName();//獲得本機(jī)名稱(chēng) Date d = new Date(); SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss"); String dateNowStr = sdf.format(d); System.out.println("IP: "+ip+" Name: "+address+" Time: "+dateNowStr); } } |
輸出結(jié)果如下：
