Exercise 4 — File handling exceptions

File handling is traditionally an area where the program has to be able to deal with all sorts of errors and unexpected results (these are collectively called ‘exceptions’ by Java programmers) Assuming that a program is well written (and therefore will not fail because of a trivial error on the part of the programmer), what can go wrong while attempting to read to data from, or write data to, a file? Some of these errors may be the result of a mistake on the part of the user, but the program must deal with them nonetheless. Try to think of at least five possible exceptions.
