Method Detail

newArrayList

public static <E> java.util.ArrayList<E> newArrayList()

Creates an empty ArrayList instance.

Note: if you only need an immutable empty List, use Collections.emptyList() instead.

Returns:

a newly-created, initially-empty ArrayList

newArrayList

public static <E> java.util.ArrayList<E> newArrayList(E... elements)

Creates a resizable ArrayList instance containing the given elements.

Note: due to a bug in javac 1.5.0_06, we cannot support the following:

List<Base> list = Lists.newArrayList(sub1, sub2);

where sub1 and sub2 are references to subtypes of Base, not of Base itself. To get around this, you must use:

List<Base> list = Lists.<Base>newArrayList(sub1, sub2);

Parameters:

elements - the elements that the list should contain, in order

Returns:

a newly-created ArrayList containing those elements
