Thank you . You were right . I didn't set up the classes correctly.
I corrected a few other errors and the program runs ok !
Below is the corrected code and the output
public class GameLauncher
  public static void main(String[] args)
   GuessGame game = new GuessGame();
   game.startGame();
/* One possible set of output is
I'm thinking of a number between 0 and 3....
I'm guessing 1
I'm guessing 3
I'm guessing 0
Player one guessed 1
Player two guessed 3
Player three guessed 0
We have a winner !
Player one got it right? true
Player two got it right? false
Player three got it right? false
Game is over !
public class Player
  int number = 0;   // the guess is stored here
  public void guess()
    number = (int)(Math.random() * 4);
    System.out.println(" I'm guessing " + number);
public class GuessGame
  public void startGame()
    int x = 0;
  Player p1 = new Player();
  Player p2 = new Player();
  Player p3 = new Player();
  int guessp1 = 0;
  int guessp2 = 0;
  int guessp3 = 0;
  boolean p1isRight = false;
  boolean p2isRight = false;
  boolean p3isRight = false;
  int targetNumber = (int) (Math.random() * 4);
  System.out.println("\n I'm thinking of a number between 0 and 3....\n");
  while(x <5)
    p1.guess();
    p2.guess();
    p3.guess();
    guessp1 = p1.number;
    System.out.println("\nPlayer one guessed " + guessp1);
    guessp2 = p2.number;
    System.out.println("Player two guessed " + guessp2);
    guessp3 = p3.number;
    System.out.println("Player three guessed " + guessp3);
    if (guessp1 == targetNumber)
      p1isRight = true;
    if (guessp2 == targetNumber)
      p2isRight = true;
    if (guessp3 == targetNumber)
      p3isRight = true;
    if ( p1isRight || p2isRight || p3isRight)
      System.out.println("\nWe have a winner ! ");
      System.out.println("Player one got it right? " + p1isRight);
      System.out.println("Player two got it right? " + p2isRight);
      System.out.println("Player three got it right? " + p3isRight);
      System.out.println("Game is over ! ");
      break; //game is over so break out of loop
    else
      //we must keep going because no one guessed the number !
      System.out.println(" Players will have to try again ! ");
    } // end of if/else
    x = x + 1;
  } // end of loop
} // end of startGame() method
} //end of class
