This is a question im just not understanding in my Object Oriented class using java

"Simon Says" is a memory game where "Simon" outputs a sequence of 10 characters (R, G, B, Y) and the user must repeat the sequence. Create a for loop that compares the two strings starting from index 0. For each match, add one point to userScore. Upon a mismatch, exit the loop using a break statement. Ex: The following patterns yield a userScore of 4:

simonPattern: RRGBRYYBGY userPattern: RRGBBRYBGY 

import java.util.Scanner;

public class SimonSays { public static void main (String [] args) { String simonPattern; String userPattern; int userScore; int i;

userScore = 0; simonPattern = "RRGBRYYBGY"; userPattern = "RRGBBRYBGY";

/* Your solution goes here */

System.out.println("userScore: " + userScore);

return; } }
