Returns a string representation of the integer argument as an unsigned integer in base 2.

The unsigned integer value is the argument plus 232 if the argument is negative; otherwise it is equal to the argument. This value is converted to a string of ASCII digits in binary (base 2) with no extra leading 0s.

The value of the argument can be recovered from the returned string s by calling Integer.parseUnsignedInt(s, 2).

If the unsigned magnitude is zero, it is represented by a single zero character '0' ('\u005Cu0030'); otherwise, the first character of the representation of the unsigned magnitude will not be the zero character. The characters '0' ('\u005Cu0030') and '1' ('\u005Cu0031') are used as binary digits.

Parameters:
i an integer to be converted to a string.

Returns:
the string representation of the unsigned integer value represented by the argument in binary (base 2).
