What is the best way to extract the first word from a string in Java?

Question

Trying to write a short method so that I can parse a string and extract the first word. I have been looking for the best way to do this.

I assume I would use s

You could use a Scanner

The scanner can also use delimiters other than whitespace. This example reads several items in from a string:

     String input = "1 fish 2 fish red fish blue fish";
     Scanner s = new Scanner(input).useDelimiter("\\s*fish\\s*");
     System.out.println(s.nextInt());
     System.out.println(s.nextInt());
     System.out.println(s.next());
     System.out.println(s.next());
     s.close(); 

prints the following output:

     1
     2
     red
     blue
