1）最簡單的獲取本機的機器名
[java] view plaincopy
import java.net.InetAddress;
import java.net.UnknownHostException;
public class GetInfo {
public static void main(String[] args) throws UnknownHostException {
InetAddress s = InetAddress.getLocalHost();
System.out.println(s.getHostName());
}
}
輸入結果：
PC-201012262159
2）獲取Java環境信息和操作系統環境信息
[java] view plaincopy
import java.util.*;
public class GetInfo {
public static void main(String[] args) {

3）獲取本機MAC地址和實時IP地址
[java] view plaincopy
import java.net.InetAddress;
import java.net.NetworkInterface;
import java.net.SocketException;
import java.net.UnknownHostException;
import java.util.Formatter;
import java.util.Locale;
public class GetInfo {
public static void main(String[] args) throws UnknownHostException, SocketException {
InetAddress address = InetAddress.getLocalHost();
NetworkInterface ni = NetworkInterface.getByInetAddress(address);
ni.getInetAddresses().nextElement().getAddress();
byte[] mac = ni.getHardwareAddress();
String sIP = address.getHostAddress();
String sMAC = "";
Formatter formatter = new Formatter();
for (int i = 0; i < mac.length; i++) {
sMAC = formatter.format(Locale.getDefault(), "%02X%s", mac[i],
(i < mac.length - 1) ? "-" : "").toString();
}
System.out.println("IP：" + sIP);
System.out.println("MAC：" + sMAC);

Map<String, String> map = System.getenv();
String userName = map.get("USERNAME");// 獲取用戶名
String computerName = map.get("COMPUTERNAME");// 獲取計算機名
String userDomain = map.get("USERDOMAIN");// 獲取計算機域名
System.out.println(userName);
System.out.println(computerName);
System.out.println(userDomain);
