The difference in performance and memory consumption between Array and ArrayList

Question

I find that I can do almost anything easily and with more control using ArrayListthan with the array in my daily coding. So I ask:

• Is it advisable to avoid arrays if I can use instead ArrayList?
• Is there something I need to keep in mind when I replace an array ArrayList?
