如何利用JAVA程序得到电脑(windows和linux)的MAC地址
1、新建一个专门用来得到电脑的MAC地址对象类，然后对其进行调用
MacAddress.java
import java.io.*;import java.util.*;import java.util.regex.*;public class MacAddress { private static final String[] windowsCommand = {"ipconfig", "/all"}; private static final String[] linuxCommand = {"/sbin/ifconfig", "-a"}; private static final Pattern macPattern = Pattern.compile(".*((:?[0-9a-f]{2}[-:]){5}[0-9a-f]{2}).*", Pattern.CASE_INSENSITIVE); private static List<String> getMacAddressList() throws IOException { ArrayList<String> macAddressList = new ArrayList<String>(); final String os = System.getProperty("os.name"); final String[] command; if (os.startsWith("Windows")) { command = windowsCommand; } else if (os.startsWith("Linux")) { command = linuxCommand; } else { throw new IOException("Unknown operating system: " + os); } final Process process = Runtime.getRuntime().exec(command); // Discard the stderr new Thread() { @Override public void run() { try { InputStream errorStream = process.getErrorStream(); while (errorStream.read() != -1) { } errorStream.close(); } catch (IOException e) { e.printStackTrace(); } } }.start(); // Extract the MAC addresses from stdout BufferedReader reader = new BufferedReader(new InputStreamReader(process.getInputStream())); for (String line = null; (line = reader.readLine()) != null;) { Matcher matcher = macPattern.matcher(line); if (matcher.matches()) { //macAddressList.add(matcher.group(1)); macAddressList.add(matcher.group(1).replaceAll("[-:]", "")); } } reader.close(); return macAddressList; } public static String getMacAddress() { try { List<String> addressList = getMacAddressList(); if (addressList.isEmpty()) { return ""; } return addressList.get(0); } catch (IOException e) { e.printStackTrace(); return ""; } } public static String[] getMacAddresses() { try { return getMacAddressList().toArray(new String[0]); } catch (IOException e) { e.printStackTrace(); return new String[0]; } }}?2、建一个主类对其进行调用
import java.io.IOException;public class test {/** * @param args */public static void main(String[] args) {MacAddress mac = new MacAddress();System.out.println("本电脑的MAC地址为："+mac.getMacAddress());} }?
