Java get CPU serial number and Nic MAC address __java

Java obtains the CPU serial number and the network card MAC address
/*
Using the commands of the runtime call operating system, the specific commands depend on the different operating systems, and do not invoke the Runtime.getruntime (). EXEC (String) interface to use Runtime.getruntime (). EXEC ( String[]) This interface, or the execution of complex commands can be problematic. Examples are as follows (take the number of CPUs, other similar):
To define a command:
Windowscmd = "cmd.exe/c echo%number_of_processors%";//windows Special
Solariscmd = {"/bin/sh", "-C", "/usr/sbin/psrinfo | Wc-l "};
Aixcmd = {"/bin/sh", "-C", "/USR/SBIN/LSDEV-CC processor | Wc-l "};
Hpuxcmd = {"/bin/sh", "-C", "Echo/" map/"|/usr/sbin/cstm | grep CPU | wc-l"};
Linuxcmd = {"/bin/sh", "-C", "Cat/proc/cpuinfo | grep ^process | Wc-l "};

Then judge the system:
OS = System.getproperty ("Os.name"). toLowerCase ();

Call different commands depending on the operating system.
