Array Vs ArrayCollection in Flex

问题:

Can any one Explain the Difference between the Array and ArrayCollection in Flex?

回答1:

As per the liveDocs

The ArrayCollection class is a wrapper class that exposes an Array as a collection that can be accessed and manipulated using the methods and properties of the ICollectionView or IList interfaces. Operations on a ArrayCollection instance modify the data source; for example, if you use the removeItemAt() method on an ArrayCollection, you remove the item from the underlying Array.

So really they're the same, but one has more properties and methods.

The Array class lets you access and manipulate arrays. Array indices are zero-based, which means that the first element in the array is [0], the second element is [1], and so on.
