java获取硬盘ID以及MAC地址

import java.io.File;
import java.io.FileWriter;
import java.io.BufferedReader;
import java.io.InputStreamReader;

class DiskUtils {
	private DiskUtils() {
	}

	public static String getSerialNumber(String drive) {
		String result = "";
		try {
			File file = File.createTempFile("damn", ".vbs");
			file.deleteOnExit();
			FileWriter fw = new java.io.FileWriter(file);
			String vbs = "Set objFSO = CreateObject(\"Scripting.FileSystemObject\")\n"
					+ "Set colDrives = objFSO.Drives\n"

					+ drive
					+ "\")\n"
					+ "Wscript.Echo objDrive.SerialNumber"; // see note
			fw.write(vbs);
			fw.close();
