模糊编译器错误 "cannot find symbol"，但未指定哪个符号

Question

*这个问题不是 "non-static method cannot be referenced from a static context?" 的重复问题，它涵盖了不同的错误消息，即 "Cannot find symbol"。

我在使用 JCreator 显示构建错误 error: cannot find symbol 时遇到问题，但未指定找到的符号。

代码：

import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
public class FanTest extends JFrame
{
    public FanTest()
    {
        setLayout(new GridBagLayout());
    //more stuff here
    }
    public void addCompsToGui(Container pane)
    {
        pane.setLayout(new GridBagLayout());
        GridBagConstraints c = new GridBagConstraints();
     //more stuff here
    }
    public static void main(String[] args)
    {
        FanTest gui = new FanTest();
        gui.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        gui.setSize(600,600);
        gui.setTitle("Test Console for Fan");
        addCompstoGui(gui.getContentPane()); // error pointing to this line
        gui.setVisible(true);
    }
}

这是家庭作业，我只是寻求帮助解决一个错误及其解决方案

Answer 1

main 是 static 并且对实例方法不可见。变化

addCompstoGui(gui.getContentPane());

到

gui.addCompsToGui(gui.getContentPane());

Answer 2

addCompstoGui(gui.getContentPane()); // java naming convention Error

gui.addCompsToGui(gui.getContentPane()); //Successfully run becoz 

        //method name should be addCompsToGui and instance should associate with ths
