Cannot resolve symbol 'getDamage'

[iYM8jXCs3pcvblTE]

Hello, everyone.
I am a newbie in "java" "forge" "gradle".
Recently I want to listen to the player's health and will perform some actions once it changes. I found the file from "
CombatEntry" method from " net.minecraft.world.damagesource.CombatEntry" but when I write the behavior to listen in my class, idea prompts me "Cannot resolve symbol 'getDamage'"

• main.java

@Mod(Utils.MOD_ID)
@Mod.EventBusSubscriber()
public class Main {
    public static DamageSource a;
    public static int b;
    public static float c;
    public static float d;
    public static String e;
    public static float f;
    @SubscribeEvent
    public static void Demo02(getDamage) {
        //CombatEntry combatEntry = new CombatEntry(a,b,c,d,e,f);
        System.out.println("sadawedawdawdawdadwa" + c);
    }
}

Is it because "forge" doesn't support "minecraft" native events, or is "getDamage" not an event that can be listened to?

getDamage is a method not a class nor an Event

Yes, I'm sorry, I just realized that the previous "AttackEntityEvent" was a class/event. And "getDamage" is a method. That's why I couldn't listen to this event. I have understood the reason.
Native events, meaning events from "minecraft", not "forge" or other third party events. (Ultimately what I want to say is whether "forge" can only call/listen to events from "forge" and not from "minecraft", or whether "minecraft" has no event system)
When I checked the "forge" event system in the past two days, I didn't find any events related to listening to player health, is this because if you want to listen to player health, you can only listen to it from events that may cause damage. (For example, when the player falls, I can only insert the action I want to perform into the method that will calculate the fall damage)

there are no Events from vanilla, all Events are added by Forge

OK, I have understood what you are trying to say and thank you very much for your patience in answering the almost common sense questions of the rookies.
