Discharging java ArrayList

Question

I`ve two methods to discharge an ArrayList in java:

1- re-assign the list object.

list = new ArrayList();

2- using clear method.

list.clear();

Which is better?

Usually I'd suggest `.clear()` to not change the refrence to the `ArrayList`, but it depends what you want to do. — xander, Aug 01 '17 at 14:42

If you have a large arraylist it may be faster to make a new arraylist than using clear. http://www.docjar.com/html/api/java/util/ArrayList.java.html
