Get a String between two Strings?

Hi!

If i have a thing like:

Hello %wWorld%, how are you?

How, can i get "World" ? I've tryed to scan for the first % token, and then split the rest.. but yeah, bad idea ._. How can i get a this thing, without nowing the lentgh? (If i now the length i can make substring or a thig like that..)

Find the first % token, substring, then find the second one. Then substring the original one again to get the string between the two tokens.

 

you could just convert that string into a char array and set the pointer to 2-6 to be added to a new string using StringBuilder?

 

might also be easier to know what your trying to accompish?

where is %wWorld% being read from?
What is %wWorld% replacing?

 

string.replaceAll("%World%", "people")

 

Splitting on % and getting the first element is probably easiest and simplest. If you want something more advanced, say you want to get multiple strings out of a single string, you could use regular expressions.

Code:

        String s = "test %world% another test %wow% awesome";
        Matcher matcher = Pattern.compile("%(.*?)%").matcher(s);
        while (matcher.find()) {
            System.out.println(matcher.group(1));
        }
