Java Netbeans For循环错误：找不到符号类，<identifier>预期？

Question

我正在制作一个刽子手游戏，这是我目前的代码：

//Declaring the array
    String [] WordList = {"anonymous", "tolerate", "appreciation", "commissioner", "harm", "flexibility", "instructional", "scramble", "casino", "tumor"};

// Getting a random word for the game
int num = ((int)Math.ceil(Math.random()*(WordList.length)));
String word = WordList[num];

// The puzzle to be displayed for the user to guess
int letters = word.length();
String hiddenWord = "";
for (int i=0; i<letters; i++){
    hiddenWord+="-";
}

在for循环中，我收到错误提示＆＃39;非法启动类型，找不到符号：class i＆＃39;。 ＆＃39;我＆＃39;应该是一个整数，我已经宣布了，所以我不确定为什么它要求上课。 还有另一个错误说，＆＃39;标识符预期＆＃39;并且那里缺少＆gt;。作为我的＆lt;用于比较（而不是作为声明或标识符），我不理解这个错误。

为了澄清，我应该补充一点，这是netbeans中的桌面应用程序。代码位于以下行之后：

public class HangmanGameView extends FrameView {

我的大部分代码都位于我的按钮的actionPerformed代码中。我需要能够从按钮的代码中访问word和hiddenWord变量，这就是我将它们放在这里的原因。如果那是问题，我不肯定。我也不确定在哪里放置代码;据我所知，没有主要方法。

编辑：我没有发布完整的代码，因为这是我现在所做的一切;其余的都是由NetBeans自动生成的，我认为它不相关。但这是：

最终编辑： 我将我的for循环移动到开始按钮代码内部 - 在开头留下hiddenWord字符串的初始声明 - 现在它正常工作。谢谢你的帮助！
