我试图通过从我的clicker类调用我的主类的方法来显示我的UI。 主要课程
package me.removed.clicker;
import me.removed.clicker.Clicker;
public class Main
{
public static void main(String[] args)
{
Clicker.getClicker().openUI();

你可以在我的主课程中看到我试图调用OpenUI但是即使我这样做没有任何反应，过程运行但没有UI打开，我尝试删除Void也没有用，如其他帖子所示。

public static Clicker instance;
在我看来，实例是null。
public static void setupClicker()
{
(Clicker.instance = new Clicker()).openUI();
}
您在哪里调用setupClicker()来初始化变量？
当您使用getClicker()方法显示用户界面时，为什么要调用setupClicker()？
