I have this line of code:

ArrayList<String>[] rows = new ArrayList[size];

IDE(Eclipse give me this warning:

Type safety: The expression of type ArrayList[] needs unchecked conversion to conform to ArrayList[]

What exactly should I do to fix this?

I need an fixed Array of unsized Lists.

There is no way to really fix that without a `@SuppressWarning("unchecked")`. – Johannes Kuhn Jan 11 '19 at 16:06

Use `ArrayList[] rows = new ArrayList<>[size];` – Shuba Jan 11 '19 at 16:10
