String of bits to byte[]
 

how can i convert a string of bit String S = "01010101010101010101"
into a byte b[]
dont worry about left over bits.. assume that the size of S is a multiple of 8-bits

Do this for each grouping of 8 bits to get your byte[].

For example, given the string "01010101010101010101":
