Java regular expression for binary string

Question

First, I need to read a binary String from file into memory - how ? To read I tried nio.CharBuffer, and then byte[]. But later I need to get a binary String with all possible binary data to do regular expression on, so it was not a success.

Then, I need to extract binary sequences from this binary string and save them in each separate binary file. Regular expr is something like this "some_string \0{4} \2.+?\0{10}", some_string followed by a space, then the \2 byte, then binary data and then 10 NULL bytes.

What would you recommend?

I'm not sure your using the right tool here, however,

make sure you are using a 1-byte encoding such as ISO-8859-1 to convert between String and byte[],
note that a '.' in a regexp excludes the end of line character, so you may want to use [\0..\255] instead
