Ok I've tried that in

 

    @SubscribeEvent
    public void ClientsTick(TickEvent.ClientTickEvent event) {
        if (event.phase == TickEvent.Phase.END) {
            if (!(TESTInventory.container.getStackInSlot(1).isEmpty())) {
                LOGGER.info("Is Not Empty");
            }
        }
    }

 

And TESTInventory.container get the IItemHandler from the capability

 

and when I load a world I get a 

java.lang.NullPointerException: null

public interface ITESTInv extends IItemHandlerModifiable {

}

And

public class TESTInventory extends ItemStackHandler implements ITESTInv {

    public static ITESTInv container;

    public TESTInventory () {
        super(8);
    }

    @Override
    protected void onContentsChanged(int slot) {
        super.onContentsChanged(slot);
    }

    @Override
    public CompoundNBT serializeNBT() {
        return super.serializeNBT();
    }


    @Override
    public void deserializeNBT(CompoundNBT nbt) {
        super.deserializeNBT(nbt);
    }
}

Its static so I can use it in a different class.

this is not the way you use a capability

you bind the capability to an object for example the World an Entity or an Item,
than you get the capability via getCapability, then do your stuff

I need to know how do i get .getStackInSlot(1) in a different class or somthing like it.

This is basic OOP, you need a reference to the object that has the capability.

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable.  If you think this is the case, JUST REPORT ME.  Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.

 

Exception: If you do not understand Java, I WILL NOT HELP YOU and your thread will get locked.

 

DO NOT PM ME WITH PROBLEMS. No help will be given.
