将对象添加到arraylist会产生标识错误？ [英] Adding an object to a arraylist creates an identifier error?

问题描述

我正在处理的一个小组项目中有一些很长的代码。我们都将自己的单独类添加到军队类中，该类包含显示每个不同类的GUI（如Archer，Ninja，Catapult等）。



无论如何，我想创建一个记录军队实例化的每个对象的ArrayList。但是，一旦我尝试向ArrayList添加任何东西，它就会给我错误< identifier> ;预期。



我添加它们时这两行编译正常：

I have some big long code from a group project I'm working on. We all add our own separate classes to an "Army" class that consists of a GUI showing each of our different classes (like "Archer, Ninja, Catapult, etc.).

Anyway, I want to create an ArrayList that records each of the objects instantiated by the Army. However, as soon as I try to add anything to the ArrayList, it gives me the error <identifier> expected.

These two lines compile fine when I add them:

   ArrayList<object>armyList = new ArrayList<object>();
   Warrior warrior = new Warrior();
But as soon as I add the line <pre lang="java"> armyList.add(warrior);

它给了我上面提到的错误。



发生什么事了？ />


这是完整的鳕鱼陆军的一员（我不想把这个问题空间搞得一团糟）。



我试过的：



广泛研究互联网。确保我正确地声明并添加到ArrayLists。将问题隔离到一个单独的文件中。

It gives me the aforementioned error.

What's going on??

Here's the full code of the Army class (I didn't want to clutter up this question space with the full thing).

What I have tried:

Researching the Internet extensively. Making sure I am declaring and adding to ArrayLists correctly. Isolating the problem into a separate file.

推荐答案

结果我无法直接在类中调用方法（如.add（）方法），而不是一个方法。问题解决了：/

Turns out I couldn't call methods (like the .add() method) from directly within the class, not in a method. Problem solved :/
