Cannot find symbol

If i try to run the exact same code as shown in the vid at min 3:32 i got an error saying 

com/teamtreehouse/override/Main.java:6: error: cannot find symbol
        System.out.println(mycheese);
                           ^
   symbol:   variable mycheese
   location: class Main
   1 error

My SDK ist set to "temurin-17" and Compiler output is defined too.

All this error is saying is that there is an attempt to reference "mycheese" but that it has not been declared. To help identify the actual issue, we'd need to see the rest of the code, or you could share a link to a workspace snapshot.

Hi, thank you for your reply. Here is what my Main.java looks like: 

package com.teamtreehouse.override;

public class Main {
    public static void main(String[] args) {
        Cheese myCheese = new Cheese();
        System.out.println(mycheese);
    }
}

and my Cheese.java:

package com.teamtreehouse.override;

public class Cheese {
    public String toString(String something){
        return "String cheese!";
    }
}

If the problem is a missing reference, why does it work in the video though?

It's a spelling issue. The symbol previously declared is "myCheese" (with a capital "C"), but the undefined reference is to "mycheese" (all lower case).

The working code in the video has a reference to "myCheese", spelled the same as it was declared.
