asked on

some conversion problems

I have a program which does conversion.

For example,

12345678ABCD0000

should be represented as 0x12 0x34 0x56 0x78 0xAB 0xCD 0x00 0x00

Note that 2 digits is represented as one byte.

This is how I stored:

byte b[];
b = {0x12, 0x34, 0x56, ......... , 0x00}

If I were to code like ....toHexString(0x00), the output is 0. Now I want the output to be 00 and not 0.

Any suggestions?

ops...sorry...this doesnt work....
the easiet way i can think off is

String test = Integer.toHexString(0x00);
if (test.length()==1)
    test = "0" + test;

hope this helps...:)
 

String out = Integer.toHexString(b[i]);

return out.length() == 1 ? "0" + out : out;

DecimalFormat decimalFormat = new DecimalFormat("00");
String hexString = decimalFormat.format(0x00);
System.out.println(hexString);// prints 00
hi yongsing...
think this might not work for 0x0a...
