In java, without Arrays and using only String methods ( don't use String builder)
// Question 17: In MS-DOS, a file name consists of up
// to 8 characters (excluding '.', ':', backslask, '?',
// and '*'), followed by an optional dot ('.' character)
// and extension. The extension may contain zero to three
// characters. For example, 1STFILE.TXT is a valid filename.
// Filenames are case-blind.
//
// Write and test a method that takes
// in a String, validates it as a valid MS-DOS file
// name, appends the extensions ".TXT" if no extension
// is given (that is, no '.' appears in FILENAME), converts
// the name to uppercase, and returns the resulting string
// to the calling method
// If fileName ends with a dot, remove that dot and do not
// append the default extension. If the name is invalid,
// validFileName should return null.
public String validFileName(String n)
