Formatting a byte array to string in java
- by rgksugan
I am using this code to find the MAC address of a machine.This code prints directly the MAC address, but i want to return it as a string.I am completely confused.
please help.
try {
InetAddress add = InetAddress.getByName("10.123.96.102");
NetworkInterface ni1 = NetworkInterface.getByInetAddress(add);
if (ni1 != null) {
byte[] mac1 = ni1.getHardwareAddress();
if (mac1 != null) {
for (int k = 0; k < mac1.length; k++) {
System.out.format("%02X%s", mac1[k], (k < mac1.length - 1) ? "-" : "");
}
} else {
System.out.println("Address doesn't exist ");
}
System.out.println();
} else {
System.out.println("address is not found.");
}
} catch (UnknownHostException e) {
e.printStackTrace();
} catch (SocketException e) {
e.printStackTrace();
}
