Hi,

I think you should write



If you want to write a \ in a String literal you have to write \\, anyway Java compiler interprets it as an escape character. Since no such escape characters as \T or \d the java compiler reports an error.

Miklos is indeed correct, shifting to the beginners forum, more people will gain benefit from this if they search there.

Another option is using forward slashes. File is smart enough to convert those to backslashes when accessing the actual file system.

Generally speaking, when the compiler gives you an error message, it tells you more than just "illegal escape character". It will show you the line and even the exact spot it thinks the error actually is:


It GREATLY helps people help you if you post the ENTIRE message. This lets a reader instantly focus in on where the problem is, rather than having to parse you entire java file and GUESS.

Just a little helpful tip for next time.

There are only two hard things in computer science: cache invalidation, naming things, and off-by-one errors
