代码没有在java中输入正确的答案

Question

这是我的工作代码。但是，一个小问题。我似乎无法输入正确的答案。代码总是只重复＆＃34;不正确。错误答案......＆＃34;即使我输入的答案是＆＃34; slowbro＆＃34;，＆＃34; Slowbro＆＃34;和＆＃34; SLOWBRO＆＃34;。如果有人可以帮我修改以下代码，我将非常感激：

public void PokemonQuiz ()
{
char again = 'y';
while (again == 'y' ||  again == 'Y') {
 String ans = IBIO.inputString ("\nUnscramble: OBORSLW (Hint: Shelder latches onto its tail.) ");
 int tries = 0;

 while (ans != "slowbro" || ans != "Slowbro" || ans != "SLOWBRO") {
  System.out.println ("Incorrect. Wrong answer. Try again.");
  tries++;
  ans = IBIO.inputString ("\nUnscramble: OBORSLW (Hint: Shelder latches onto its tail.) ");

  if (tries > 3)
  {
   System.out.println ("The correct answer was SLOWBRO.");
   again = IBIO.inputChar ("Play again? (y/n) ");

   if (again != 'y' || again != 'Y')
    break;
  }
  }
  System.out.println ("Correct.");
  }

编辑：我知道＆＃34; ==＆＃34;应替换为＆＃34; .equals（）＆＃34;但那我怎么会改变＆＃34;！=＆＃34; ??
