1.19.2 !1.19.2-43.3.13 Cant get my tab code to not syntax no matter everything i've tried

[HHYPER_Red]

import net.minecraft.world.item.CreativeModeTab;
import net.minecraft.world.item.ItemStack;


public class sbcTab {
    public static final CreativeModeTab SBCTAB = new CreativeModeTab("StayBackCretin!") {
        @Override
        public ItemStack makeIcon() {
            return null;
        }
    };
}

Everything I've tried so far has been met with nothing, currently in this code the (@Overide) is causing this error to show : 'Method does not override method from its superclass' but after removing it, trying other things I've always been met with the other one : 'Required type: Builder   Provided: String' or sometimes even both in my attempts, someone help please

OK Holy WOW, so the leading problem can be multiple things but my experience is really just stupid, the version I was using wasn't the issue, so... when you load a file as an intelij project it creates an .idea folder and if that isn't in the same folder as the build.gradle file it wont let you go in and change the project build sdk to match the one you need and as default there isnt one it dosent just default, needless to say problem solved
