I need Java regular expression to match String which contains lowercase or uppercase or 1 or more hyphens and may end in period(.) comma(,) question mark(?) exclamation mark(!)

example: done-done, Done!, where?, Ahhh! are some of the inputs that should satisfy the regex

I came up with "^([a-z][A-Z]) ! (.|,|\\?|!)?$") but not working as expected, appreciate anyone can help me with this.

CodePudding user response：

See if this regex helps you:

^[a-zA-Z\-] [\.,!?]?$

If you need to accept an empty string as well, you should use a *:

^[a-zA-Z\-]*[\.,!?]?$

Bear in mind that the above regex will also accept strings that only contain . , ! or ?.
