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

Another alternative is to use some library supporting AST parsing, for e.g. org.eclipse.jdt.core has all the APIs you need to do this and more. But then that's just one alternative:)
