Question

I have a string, with characters a-z, A-Z, 0-9, (, ), +, -, etc.

I want to find every word within that string and replace it with the same word with 'word' (single quotes added). Words in that string can be preceded/followed by “(“, “)”, and spaces.

How do I go about doing that?

Input:

(Movie + 2000)

Output:

('Movie' + '2000')

Answer 1

As stated in the comments, regex is a good way to go:

String input = "(Movie + 2000)";

input = input.replaceAll("[A-Za-z0-9]+", "'$0'");

You don’t give a precise defition of ‘word’, so I assume it is any combination of letters and numbers.

EDIT OK, thanks to @Buhb for explaining why this solution is not the best one. Better solution was given by @Bohemian.
