In order to override a method in a given class, you would have to 
create a subclass of that class, and then define a method in the 
subclass that has the exact same signature as the method defined
in the superclass.

However, the String class is declared "final", which means that you 
cannot extend it.

It looks like you are really just trying to write a utility method in 
your class that works on Strings, and there is no problem with that.  
But you reference your replace() method as a String member class, and 
that is not correct.  From what you posted, it looks like you could 
simply change the call to:

   replace(s,"//:","package c");
