Replace first and last character upon condition (which method is faster)?

I have a list of thousands of strings that may come in the form:

word

or

"more than one word"

I want to remove the "" whenever they are present, so that I can save the string to my DB.

I'm wondering which method is faster:

  1. Using line.replace("\"","");
  2. Validating that first character is '"', then making a substring from character 1 to length - 1.

Or even, is there a better way to do this?

The second method is faster. It will perform at most one character comparison and one array copy, instead of comparing all characters in the string with the " character.
