How to declare multiple arraylists in Java

Question

I want to declare multiple arraylists but i failed to do so. Is there a way to it? here's my failed code:

List<Integer>[] table = new ArrayList<Integer>[]();

It seems no matter how and where do i put '[]' , it just doesn't work. any help or suggestion would be appreciated

Answer 1

You have to specify the size like this:

ArrayList<Integer>[] table = new ArrayList[10];

Creates an array of ArrayList with capacity of 10.

Answer 2

@SuppressWarnings("unchecked")
List<Integer>[] table = (ArrayList<Integer>[]) Array.newInstance(ArrayList.class, size);

Answer 3

List<Integer> multiple = new ArrayList<String>(), myArray = new ArrayList<String>();

希望能帮助到你。
