if we have a byte value EX: 11111111 where 1 in first digit place shows that its negative number, how to get back the decimal number which will be negative.

You can convert it to an int, and then convert this into a byte:
int i = Integer.parseInt ("11111111", 2); byte b = (byte) i;
The casting in the second line is needed, to avoid the compilerwarning 'possible loss of precision'.
