Java - regular expression finding comments in code

Question

A little fun with Java this time. I want to write a program that reads a code from standard input (line by line, for example), like:

// some         


        

Answer 1

I think a 100% correct solution using regular expressions is either inhuman or impossible (taking into account escapes, etc.).

I believe the best option would be using ANTLR- I believe they even provide a Java grammar you can use.
