游戏运行良好，但我不知道如何获得获胜者。

  1. 我不确定我需要在代码中的确切位置放置它。

  2. 首先我试过

    if((jButton1.getText())==(jButton2.getText())&&((jButton2.getText())==(jButton3.getText()){

    ganador =真；
    }

但它说它缺少返回语句。然后我更改了代码以使用 .equals 但它说它再次缺少返回语句。

     if(jButton1.getText().equals(jButton2.getText()) && (jButton2.getText.equals(jButton3.getText)) && (jButton2.getText() != "") {
  ganador = true;        
}

另外，我将这部分代码放在最后，但不确定这是否是问题所在。

中的getText()函数AbstractButton返回 a String，在 java 中您需要Strings使用该.equals(otherString)函数进行比较

编辑：关于您丢失的退货声明。这也意味着您的代码并不像所有这些方法一样完整void。但是如果你说一个函数是:public boolean doSomething()那么你需要一个实际返回一个boolean诸如:的 return 语句return ganador。

为了进一步说明 Simon 所说的，您希望按照以下方式实施： jButton1.getText().equals( jButton2.getText() )
