How to take scanner input without space

I have a homework question that wants me to write a

Program that takes three names and their scores from a user by using delimiters. Example:

Tom:54, Matt:12, Ali:89

I keep getting an input mismatch exception when Java is assigning user2Score. I am currently testing my program but scanner seems to take in user2 as " Matt" instead of "Matt". I'm not sure if my delimiter syntax is correct. Any feedback would be greatly appreciated!

import java.util.Scanner;

public class General {

    public static void main(String[] args) {

        Scanner input = new Scanner(System.in).useDelimiter("[: | ,*\\s]");

        String user1;
        String user2;
        String user3;

        int user1Score;
        int user2Score;
        int user3Score;

        System.out.println("Please enter the user name and their score:");
        user1 = input.next();
        user1Score = input.nextInt();
        user2 = input.next();
        user2Score = input.nextInt();
        user3 = input.next();
        user3Score = input.nextInt();


        System.out.println(user1 + " " + user1Score + "\n" + user2 + " " + user2Score);
    }

}

you can use the trim()-method of String. This elimates all spaces at the beginning and at the end of the string.
