Have you been through the String class, particularly what they call the parameters to the replaceAll method, and what they are described as? Have you been through the links given in the method description, and I trust you are familiar with what they mean? If not, read the Java Tutorials section.

And remember that | is a meta-character, but you might not have that problem if you use | in the right-hand parameter.

I have tried it, and it is easier than I thought. As long as I have understood your request properly!

Correct: the 2nd parameter is not a regex-aware String. But the $ followed by a number is used to interpolate a matched group from the first parameter (the regex aware String). So, only the '$' needs escaping in the 2nd parameter.
