The problem you describe can be solved without using regular
expressions at all:
String original = ...;
String replaced = original.replace("'", "''");

No, not without (1) the code you are trying to compile and
(2) the *exact* error message or messages the compiler emits.

It's not clear to me what "do the same" means. The replaceAll()
calls you show seem to have nothing to do with the problem you say
you are trying to solve -- in fact, some of them are nonsensical to
the point that I think they would throw exceptions at run-time (not
compile-time). If the replace() call above doesn't meet your needs,
please show your actual code and your actual error messages, and
give a fuller description of what you're trying to do.
