Question

"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: R, R, G, B, R, Y, Y, B, G, Y
import java.util.Scanner;

public class SimonSays {
public static void main (String [] args) {
String simonPattern = "";
String userPattern = "";
int userScore = 0;
int i = 0;

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


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

return;
}
}

Answer:

import java.util.Scanner;

public class SimonSays{

    public static void main(String []args)

    {

       String simonPattern = "";

       String userPattern = "";

       int userScore = 0;

       int i = 0;

       userScore = 0;

       simonPattern = "RRGBRYYBGY";

       userPattern = "RRGBBRYBGY";

       for(i=0 ; i<simonPattern.length(); i++)

       {

           if(simonPattern.charAt(i)==userPattern.charAt(i))

           {

               userScore+=1;

           }

           else

           {

               break;

           }

           

           

       }

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

 

    }

}

Explanation:

the string method charAt() is used to access each character of the string.
