Is there any Regex optimizer written in Java?

Question

I wrote a Java program which can generate a sequence of symbols, like \"abcdbcdefbcdbcdefg\". What I need is Regex optimizer, which can result \"a((bcd){2}ef)

Answer 1

Regular expressions are not a substitute for compression

Don't use a regular expression to represent a string constant. Regular expressions are designed to be used to match one of many strings. That's not what you're doing.
