如何通过Java获取本地主机的厂商信息以及序列号啊?请各路神仙帮帮忙!在此谢过!

主机的厂商信息以及序列号需要Windows编程
下面是代码。你研究一下：
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.net.InetAddress;
import java.net.NetworkInterface;
import java.net.SocketException;
import java.net.UnknownHostException;
import java.util.Properties;

/**
* 获取当前系统信息
* @author gxsn
*
*/
public class SystemInfo {
//当前实例
private static SystemInfo currentSystem=null;
private InetAddress localHost=null;

private SystemInfo()
{
try {
localHost = InetAddress.getLocalHost();
} catch (UnknownHostException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}

/**
* 单例模式获取对象
* @return
*/
public static SystemInfo getInstance()
{
if(currentSystem==null)
currentSystem= new SystemInfo();
return currentSystem;
}
/**
* 本地IP
* @return IP地址
*/
public String getIP()
{
String ip=localHost.getHostAddress();
return ip;
}
/**
* 获取用户机器名称
* @return
*/
public String getHostName()
{
return localHost.getHostName();
}

/**
* 获取C盘卷 序列号
* @return
*/
public String getDiskNumber()
{
String line = "";
String HdSerial = "";//记录硬盘序列号

try {

Process proces = Runtime.getRuntime().exec("cmd /c dir c:");//获取命令行参数
BufferedReader buffreader = new BufferedReader(
new InputStreamReader(proces.getInputStream()));

while ((line = buffreader.readLine()) != null) {

if (line.indexOf("卷的序列号是 ") != -1) { //读取参数并获取硬盘序列号

HdSerial = line.substring(line.indexOf("卷的序列号是 ")
+ "卷的序列号是 ".length(), line.length());
break;
}
}

} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

return HdSerial;
}

/**
* 获取Mac地址
* @return Mac地址，例如：F0-4D-A2-39-24-A6
*/
public String getMac()
{
NetworkInterface byInetAddress;
try {
byInetAddress = NetworkInterface.getByInetAddress(localHost);
byte[] hardwareAddress = byInetAddress.getHardwareAddress();
return getMacFromBytes(hardwareAddress);
} catch (SocketException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return null;
}

/**
* 获取当前系统名称
* @return 当前系统名，例如： windows xp
*/
public String getSystemName()
{
Properties sysProperty = System.getProperties();
//系统名称
String systemName=sysProperty.getProperty("os.name");
return systemName;
}

private String getMacFromBytes(byte[] bytes)
{
StringBuffer mac=new StringBuffer();
byte currentByte;
boolean first=false;
for (byte b : bytes) {
if(first)
{
mac.append("-");
}
currentByte=(byte)((b&240)>>4);
mac.append(Integer.toHexString(currentByte));
currentByte=(byte)(b&15);
mac.append(Integer.toHexString(currentByte));
first=true;
}
return mac.toString().toUpperCase();
}
}
