游戏没有在java石头剪刀游戏中结束

编辑：我已经修复了我的程序，使其正常工作，并添加了括号。然而，我遇到了另一个错误。当用户赢得游戏时，我的代码不会结束。我希望它结束，所以请帮帮我。下面是我的代码：

public void rockPaperScissors ()
{
System.out.println ("First one to 3 Points wins the battle!");
char again = 'y';
while (again == 'y'){
int rPoint = 0;
int uPoint = 0;
int game = 1;
System.out.println ("nLET THE BATTLE BEGIN!");
while (uPoint < 3 || rPoint < 3) {
 String user = uChoice ();
 System.out.println (user + ", I choose you!");
 String rival = rChoice ();
 System.out.println ("Your rival has chosen " + rival + "!");
 String win = winner (rival, user);
 if (win == "r")
 {
  rPoint++;
  System.out.println ("nYour rival has won the match.");
 }
 else if (win == "u")
 {
  uPoint++;
  System.out.println ("nYou have won the match!");
 }
 else 
  System.out.println ("nBoth Pokemon have fainted! It's a tie!");
 System.out.println ("Points: You " + uPoint + " Rival: " + rPoint);
 if (uPoint == 3) {
  System.out.println ("Congrats! You have beaten your rival!");
  break;
  }
 else if (rPoint == 3) {
  System.out.println ("Too bad! Your rival has beaten you!");
  again = IBIO.inputChar ("nWant to try again? (y/n) ");
  uPoint = 0;
  rPoint = 0;
  }
 }
 }
 }

public boolean isValid (String c)
{
 if (c.equals ("Bulbasaur") || c.equals ("BULBASAUR") || c.equals ("bulbasaur") || c.equals ("B") || c.equals ("b") || c.equals ("Charmander") || c.equals ("CHARMANDER") || c.equals ("charmander") || c.equals ("c") || c.equals ("C") || c.equals ("CHARMANDER") || c.equals ("SQUIRTLE") || c.equals ("Squirtle") || c.equals ("squirtle") || c.equals ("s") || c.equals ("S"))
 return true;
 else
 return false;
}
public String uChoice ()
{
printSlow ("Pokemon: Bulbasaur, Charmander, Squirtle");
String c = IBIO.inputString ("Which Pokemon do you choose? ");
while (!isValid (c))
{
 System.out.println ("You don't have that Pokemon. Try again.");
 c = IBIO.inputString ("Which Pokemon do you choose? ");
}
if (c.equals ("Bulbasaur") || c.equals ("BULBASAUR") || c.equals ("bulbasaur") || c.equals ("b") || c.equals ("B"))
 return "Bulbasaur";

else
 return "Squirtle";
}

{

 if (num == 1)
  return "Bulbasaur";
 else if (num == 2)
  return "Charmander";
 else
  return "Squirtle";
}
public String winner (String rival, String user)
{
 if ((rival == "Bulbasaur" && user == "Squirtle") || (rival == "Charmander" && user == "Bulbasaur") || (rival == "Squirtle" && user == "Charmander"))
        return "r";
