java - Java - 对象类型的方法 getValue() 未定义

Question

我有这个错误：

方法 getValue() 未为 Object 类型定义

*这是错误代码： 在行中：

final String materialName = BasePlugin.getPlugin().getItemDb().getName(new ItemStack(((Object) ((Map)dataMap).entrySet().iterator().next()).getValue().getItemType(), 1));

完整代码

什么对象generate()方法返回？你能在你的问题中添加generate()方法吗？

您尝试将其强制转换为Object

((Object) ((Map)dataMap).entrySet().iterator().next()).getValue()...

哪个（正如@MadProgrammer 所说）没有getValue()方法。如果您需要，Map您应该将其转换为Map并使用该get(Object key)方法

final String materialName = BasePlugin.getPlugin().getItemDb().getName(new ItemStack(((Map) ((Map)dataMap).entrySet().iterator().next()).get(**the key**).getItemType(), 1));

但在这种情况下，您必须知道key.
