Can I call the event method?

Can I instantiate an event/class in 'forge' to call one of its methods?
Here is the code I used as an example

package com.AJ.LifeShareing;;
import net.minecraft.world.damagesource.DamageSource;
import net.minecraft.world.entity.LivingEntity;
import net.minecraftforge.event.entity.living.LivingHurtEvent;
import net.minecraftforge.event.entity.player.AttackEntityEvent;
import net.minecraftforge.eventbus.api.SubscribeEvent;
import net.minecraftforge.fml.common.Mod;

@Mod(Utils.MOD_ID)
@Mod.EventBusSubscriber()
public class Main {
    public static LivingEntity a;
    public static DamageSource b;
    public static float c;
    public static float d;
    @SubscribeEvent
    public static void Demo02(LivingHurtEvent event) {
        LivingHurtEvent livingHurtEvent = new LivingHurtEvent(a,b,c);
        d = livingHurtEvent.getAmount();
        System.out.println("aaaaaaaaaaaaaaaaaaa" + '\n' + d);
    }
}

You can, but it won't do anything useful. The event instance is already given to you as a parameter.

I just checked the description of "LivingHurtEvent" and he tells me that the event does not return results and if I instantiate the event/class and then call his method, I can't get the return value (amount,source). Do I have to get the return value I want in some other way.
Here is the code for the "LivingHurtEvent" event

package net.minecraftforge.event.entity.living;

import net.minecraft.world.damagesource.DamageSource;
import net.minecraft.world.entity.LivingEntity;
import net.minecraftforge.common.ForgeHooks;
import net.minecraftforge.common.MinecraftForge;
import net.minecraftforge.eventbus.api.Cancelable;

/**
 * LivingHurtEvent is fired when an Entity is set to be hurt. <br>
 * This event is fired whenever an Entity is hurt in

 * {@code Player#actuallyHurt(DamageSource, float)}.<br>
 * <br>
 * This event is fired via the {@link ForgeHooks#onLivingHurt(LivingEntity, DamageSource, float)}.<br>
 * <br>
 * {@link #source} contains the DamageSource that caused this Entity to be hurt. <br>

@net.minecraftforge.eventbus.api.Cancelable
public class LivingHurtEvent extends LivingEvent
{
    private final DamageSource source;
    private float amount;
    public LivingHurtEvent(LivingEntity entity, DamageSource source, float amount)
    {
        super(entity);
        this.source = source;
        this.amount = amount;
    }

    public DamageSource getSource() { return source; }

    public float getAmount() { return amount; }

    public void setAmount(float amount) { this.amount = amount; }
}

I'm wondering if the 'forge' event is only used as a 'forge' listener and not for other purposes. That is, after these events are instantiated, the method is called and cannot provide any return value, or after instantiation, the method is called and cannot change the data, because the events/classes are only used to listen to minecraft/forge.

Thanks for the tip, I managed to get the data I wanted in the return parameters of the listened event.
Here is part of the code

    @SubscribeEvent
    public static void Demo02(LivingHurtEvent event) {
        System.out.println("sadawedawdawdawdadwa" + '\n' + event.getAmount());
    }

why, you have Event instance so call the getters

we all have the code of the Event

the Event exist to perform an action at a specific 'time'/'action' in the game

Mr. diesieben07 und Mr. Luis_ST. Ich danke Ihnen für Ihre Geduld.
Erst jetzt habe ich gelernt, dass "Listen Events" als Parameter zurückgegeben werden, also habe ich auch gelernt, dass man Methoden direkt mit Parametern aufrufen kann.
Ich stelle den Ereigniscode zur Verfügung, weil es sich um ein geringfügiges Problem handelt und ich ein sehr schlechter Fragesteller wäre, wenn Sie auch für dieses Problem den Ereigniscode selbst durchgehen müssten.
Ich verwende derzeit ein Übersetzungsgerät, um mit Ihnen zu kommunizieren, daher werden viele Wörter nicht klar und deutlich zu verstehen sein, und ich entschuldige mich für etwaige Missverständnisse.
Ich bin Ihnen beiden dankbar, dass Sie sich trotz Ihres vollen Terminkalenders die Zeit genommen haben, um meine Fragen zu beantworten. Ich gebe Ihnen beiden ein Dankeschön, um meine Dankbarkeit auszudrücken.
Ich danke Ihnen nochmals. :):)
