如何在点击游戏中更新JLabels？

标签： jlabel

我参加了一个编程和解决问题的课程，而我们这个实验室给了我一些麻烦。我们的教授已经写出了游戏的基本代码＆＃34; Cookie Clicker＆＃34;并且已经要求我们填写剩下的部分以使游戏真正起作用（如果你还不熟悉游戏，那么你很可能无法提供帮助）。截至目前，游戏已经拥有了所有按钮，但是如果你点击它们中的任何一个，则没有任何反应。如果有人可以告诉我如何更新JLabel，以便按钮每次点击时都显示正确的数字，那么我们将非常感激。需要代码的部分由// Start和// End标记，几乎一直在底部。

public class CookieClickerGUI extends javax.swing.JFrame {
//Instance variables
public int cookies;
public int cursors;
public int grandmas;
public int farms;
public int factories;

//Getters
public int getCookies()
{
    return cookies;
}

    return cursors;

    this.cookies = cookies;
}

    this.grandmas = grandmas;
}

{
    this.farms = farms;
}

{
    this.factories = factories;
