I had very errorsome Exception handling with if-clauses. An exception occurs if not found path. An exception returns the function again. The function is recursive. Safe?

$ javac SubDirs.java 
$ java SubDirs
Give me an path.

Give me an path.
IT WON'T FIND ME, SO IT RETURNS ITSELF due to Exception caught
Give me an path.
