Bitwise XOR operator

Hi Frens,
This is my first post here, I am trying to learn more about Bitwise operators. I want to hide the parameters in my java code. The logic i am trying to use is i use bitwise xor operator to encrypt the value and then use the encrypted value. but i don't know how to get it back.

for example
if i do (') XOR (\034) i get (w).
now how do i get back (') from (w). any other bitwise operator which can reverse the results of the XOR operator.

ne pointers for this are welcome.................

TIA

10101010 (eg if this was ' but its not xor'ed with
11001100 (your w)
-------- gives
01100110 (encrypted)


01100110 xor encrypted
11001100 with w again
-------- gives
10101010 ' again


hope this helps dude.
