我目前正在使用Java制作一个自定义Hangman游戏，并且已进入JPanel上显示按钮的阶段。我没有按钮工作，因为letterA actionListener中的if语句将无法访问。此外，单击时，这些字母不会更新显示被绞死人员的Hanger类的图形。有人可以帮忙看看为什么letterA if语句将无法访问并修复它。我已经尝试使用多个System.out.println()语句来查看程序是否曾在letterA actionListener中输入if if语句而它没有。请记住，我没有得到HangmanWord中的字母来点击时改变颜色。任何建议或帮助都会很棒。
This is an example of clicking the letter A button and not having any drawing appear (the head is already supposed to be there because I set the count to a number other than 0.
