用JAVA得到本机MAC地址 参考

import java.io.*;

			//Process process = Runtime.getRuntime().exec("E:\\QQ\\QQ.exe" );
			/*System.out.println("begin to read mac address" );

			System.out.println( line );

	public static void main(String[] args) 
	{
		System.out.println("Hello World!");
		System.out.println( "本机的MAC地址是：" + ReadMAC.checkPhysicalAddress() );
