First one, as you're reusing the same object. But calling new operator will create a new object. — Saif Ahmad, Dec 06 '17 at 10:19

I think if u just clear it its 1 less object for GC to handle, so its better.

I dont see any actual advantage on creating a new array list object if not changing the type.
