Can't understand the meaning of "cannot find symbol error" in my code

Question

My code keeps getting 6 errors called "Cannot find symbol", I've gone over my code and cannot understand where this issue is coming from in the given locations

symbol:   method prtIntro()
  location: variable session of type Session
/tmp/H9bVKeD6Jn/Session.java:68: error: cannot find symbol
            session.setTurns();
                   ^
  symbol:   method setTurns()
  location: variable session of type Session
/tmp/H9bVKeD6Jn/Session.java:71: error: cannot find symbol
            for (int i = 0; i < session.getTurns(); i++) {
                                       ^
symbol:   method getTurns()
  location: variable session of type Session
/tmp/H9bVKeD6Jn/Session.java:75: error: cannot find symbol
                game.setPairBonus();
                    ^
  symbol:   method setPairBonus()
  location: variable game of type Game
/tmp/H9bVKeD6Jn/Session.java:76: error: cannot find symbol
                game.setSeven11Bonus();
                    ^
  symbol:   method setSeven11Bonus()
location: variable game of type Game
/tmp/H9bVKeD6Jn/Session.java:77: error: cannot find symbol
                game.setTotal();
                    ^
symbol:   method setTotal()
  location: variable game of type Game

I've attached my code below so if someone could explain how I can resolve these issues I would greatly appreciate it

import java.util.Random;
import java.util.Scanner;

// The Game class handles the game logic and calculations
class Game {
    private Random random = new Random();
    private int die1;
    private int die2;
    private int sum;
    private int pairBonus;
    private int seven11Bonus;
    private int total;

    public void setDice() {
        die1 = random.nextInt(6) + 1;
        die2 = random.nextInt(6) + 1;
        sum = die1 + die2;
    }

    public void sortDice() {
        if (die1 > die2) {
            int tempDie = die1;
            die1 = die2;
            die2 = tempDie;
        }
    }

    // Other getter and setter methods for various calculations
    // ...

    // More methods for setting and getting bonuses and totals
    // ...
}

// The Session class manages player information and interaction
class Session {
    private Scanner scan = new Scanner(System.in);
    private String name;
    private int turns;

    public void setName() {
        System.out.print("Enter your name: ");
        name = scan.nextLine();
    }

    // Other methods for getting player information and printing messages
    // ...

    public void prtOutro() {
        System.out.println("Thanks for playing, " + name + "! See you next time.");
    }
}

// The main Driver class runs the game
public class Driver {
    public static void main(String[] args) {
        Scanner input = new Scanner(System.in);
        Game game = new Game();
        Session session = new Session();
        String playAgain;

        // Get player name and display welcome message
        session.setName();
        session.prtIntro();

        do {
            // Get the number of turns from the player
            session.setTurns();

            // Loop through the specified number of turns
            for (int i = 0; i < session.getTurns(); i++) {
                // Set up the game for this turn
                game.setDice();
                game.sortDice();
                game.setPairBonus();
                game.setSeven11Bonus();
                game.setTotal();

                // Display the results of this turn
                System.out.println("\nRoll " + (i + 1) + ":");
                // Display other information using the game's getter methods
                // ...

            }

            // Ask if the player wants to play again
            System.out.print("\nDo you want to play again? (Y/N): ");
            playAgain = input.next();
        } while (playAgain.equalsIgnoreCase("Y"));

        // Display a goodbye message
        session.prtOutro();
    }
}

I attempted to change the formatting of the code and experimented with deleting certain elements yet each came with a progressively different issue
