Declaring String Variables within a while loop without it looping all throughout - java

Question

I am stuck at a part where I am supposed to declare a string variable called "phrase", where it shouldn\'t loop, all the way through.

to give you an idea my tas

1. You can reuse the same variables for individual points i.e. pointsW and pointsO because you do not want to retain their values till the end where you are publishing the results. The same is the case with the variable for the loop condition i.e. go and the variable used for inputting win/loss i.e. letter.

2. You will need arrays or different variables for storing total points, countings, and team name.

   import java.util.Scanner;
   
   public class Standings {
       public static void main(String[] args) {
           Scanner keyboard = new Scanner(System.in);
           int option = keyboard.nextInt();
           int pointsW = 0;
           int pointsO = 0;
           String letter;
           boolean go = true;
           if (option == 2) {
               // Variables for total points, counting, and name for the first team
               int playedGamesTeamOne = 0;
               int teamOnePoints = 0;
               String teamOneName = keyboard.next();
               while (go) {
                   letter = keyboard.next();
                   if (letter.equals("W")) {
                       pointsW += 2;
                   } else if (letter.equals("O")) {
                       pointsO++;
                   }
                   playedGamesTeamOne++;
                   if (letter.equals("N")) {
                       teamOnePoints = pointsW + pointsO;
                       playedGamesTeamOne--;
                       go = false;
                   }
               }
   
               // Reset common variables
               go = true;
               pointsW = 0;
               pointsO = 0;
   
               // Variables for total points, counting, and name for the second team
               int playedGamesTeamTwo = 0;
               int teamTwoPoints = 0;
               String teamTwoName = keyboard.next();
               while (go) {
                   letter = keyboard.next();
                   if (letter.equals("W")) {
                       pointsW += 2;
                   } else if (letter.equals("O")) {
                       pointsO++;
                   }
                   playedGamesTeamTwo++;
                   if (letter.equals("Q")) {
                       teamTwoPoints = pointsW + pointsO;
                       playedGamesTeamTwo--;
                       go = false;
                   }
               }
   
               System.out.println(teamOneName + " has played " + playedGamesTeamOne + " games and has earned "
                       + teamOnePoints + " points");
               System.out.println(teamTwoName + " has played " + playedGamesTeamTwo + " games and has earned "
                       + teamTwoPoints + " points");
               if (teamOnePoints > teamTwoPoints) {
                   System.out
                           .println(teamOneName + " is in first place by " + (teamOnePoints - teamTwoPoints) + " points");
               } else {
                   System.out
                           .println(teamTwoName + " is in first place by " + (teamTwoPoints - teamOnePoints) + " points");
               }
           }
       }
   }
