binary and text conversion java

Ok, I have a text file with the 1's and 0's that is the exact binary of file.
Basically I need to create a file who's binary is exactly the 1's and 0's that are in that text. Please don't ask how I got it or anything. Just how to create a file who's binary is those 1's and 0's. if you could show me some code in java that would do this I would love you forever.

btw the binary is meant to be 8bit

There are certain tools on web which can help you for this. You will need to just find the right convertor on google. There are many programmers who had uploaded a ready to use code for this purpose. Or else you can also find sample codes from web. I had seen many sites offers a online version of convertor which converts many characters to text.
