Remove trailing whitespace and terminating character

String val = "this is a string        *"

I am attempting to remove the final character '*' along with any preceding whitespace with the following output:

String result = "this is a string"

What's the simplest and sturdiest approach to doing this?

Should I substring the final character and trim the string or use regex?

For matching you can use:

\s*\*$

Which is 0 or more whitespace characters followed by literal * character with anchor $ to assert end of line.

That needs to be replaced by empty string "" to remove it.
