Get MAC address using Java

Getting MAC address of any system is very simple. But how can we get the MAC address programmatically  using Java ? 

Let see, how it is possible in Java ?

try{

           String IP  =InetAddress.getLocalHost().getHostAddress();//get the system ip address

         //System.out.print(IP);

          String hostname=InetAddress.getLocalHost().getHostName();//get the system name

        

        //get mac addrress

        

        InetAddress inet=InetAddress.getLocalHost();

        NetworkInterface network = NetworkInterface.getByInetAddress(inet);

byte[] mac = network.getHardwareAddress();

//System.out.print("Current MAC address : ");

StringBuilder sb = new StringBuilder();

for (int i = 0; i < mac.length; i++) {

sb.append(String.format("%02X%s", mac[i], (i < mac.length - 1) ? "-" : ""));

}

String mac1=sb.toString();// Get the Mac Address in a string

}

catch(Exception e)

{

}
