How to convert a binary representation of a string back into a string?

Question

I have a string that was converted to binary with Integer.toBinaryString() on each of its characters. The binary string was then mangled a bit (random bit flips) and I'd like to convert it back into a string. Are there any simple methods for this in java?

Answer 1

Yes, you can easily do it using Integer.parseInt(String s, int radix).

In your case the radix is 2 so you just have to split your whole binary string in substrings of 8 chars each and use Integer.parseInt(substring, 2). Then you convert them to characters and you concatenate them..
