Doubt regarding regex

[archu sweet]

public class Test {
	
	public static void main(String... args) {
            
		
		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(); 
		

	}
}




ANSWER:
1 2 red blue

I just came across this code in mocktest...I need to know what's \\s* for? whitespace? and what does useDelimiter acrually do??
