What you are doing requires a bitstring not an integer. If you really need to convert this bitstring to an integer then you need to do Integer.parseInt(string, 2) ; What you probably should do, if you really need to pass an integer, rather than the bitstring in string form is to ...

This value is converted to a string of ASCII digits in octal (base 8) with no extra leading 0s. The value of the argument can be recovered from the returned string s by calling Integer.parseUnsignedInt(s, 8). If the unsigned magnitude is zero, it is represented by a single zero ...
