在第 3 行的这段代码中，我不断收到“操作符 == 未定义参数类型 boolean、int”：

    public void loadState(int i)
  {
      if (statesSaved[i] == 0)
      {
        return;
      }
      List list = TMIUtils.getMinecraft().h.at.e;
      for (int j = 0; j < 44; j++)
        {
          sx slot = (sx)list.get(j + 1);
          slot.c(null);
          ul itemstack = TMIUtils.copyStack(states[i][j]);
          if ((itemstack == null) || (itemstack.c < 0) || (itemstack.c >= sv.f.length) || (sv.f[itemstack.c] == null))
            continue;
          slot.c(itemstack);
    }
  }

我不知道为什么会发生这种情况，因为我有另一个类文件，其中没有错误。

Java 与 C 不同，C 允许在某些情况下将变量视为不同的类型有很大的自由度，它在允许您执行的操作方面更加严格。您的两条有问题的行是：

private static boolean[] statesSaved = new boolean[7];
if (statesSaved[i] == 0)

您需要将最后一个重新编码为：

if (!statesSaved[i])

而且，如果您重视那些将维护您的代码的人的理智，请不要使用以下内容：

if (statesSaved[i] == false)

永远不需要明确比较布尔值。您应该选择智能名称，例如hasSavedStateorisBroken这样的表达式：

if (isBroken)

或者：

while (!finished)

用英语说得通。这将大大提高代码的可读性。

无论如何，由于布尔值的显式比较会导致另一个布尔值，你会在哪里停下来。减少荒谬的历史悠久的传统需要如下代码：

if (((finished == true) == true) == true) ...

正如错误消息所述，您的代码毫无意义；你不能写if (boolean == int)。

你可能是说if (statesSaved[i] == false)
