Java doesn’t call any of its List implementations “array”. There’s ArrayList, which just means a list implemented on top of an array (actually multiple arrays in the general case, since it has to switch between arrays when increasing capacity). It doesn’t mean that it is an array, any more than a stack implemented on top of an array is an array (it isn’t).
