check if arraylist is NOT empty java

I know the isEmpty() method used to check if an arraylist is empty, but I am trying to check if an arraylist is not empty. I tried to look online but I didn't find any useful information on how to do this. My code is like "while ArrayList is not empty then run code).


Invert the result of isEmpty().

public boolean notEmpty(ArrayList a) {
    return !a.isEmpty();

That will tell you when a list is not empty.
