Method Detail

newArrayList

public static <E> ArrayList<E> newArrayList()

Creates an empty ArrayList instance.

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

Returns:

a new, empty ArrayList

newArrayList

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

Creates an ArrayList instance containing the given elements.

Note: if you need an immutable List, use ImmutableList instead.

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 new ArrayList containing those elements

newArrayList

public static <E> ArrayList<E> newArrayList(Iterable<? extends E> elements)

Creates an ArrayList instance containing the given elements.

Parameters:

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

Returns:

a new ArrayList containing those elements

newArrayList

public static <E> ArrayList<E> newArrayList(Iterator<? extends E> elements)

Creates an ArrayList instance containing the given elements.

Parameters:

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

Returns:

a new ArrayList containing those elements

newArrayList

public static <E> ArrayList<E> newArrayList(@Nullable
                            E first,
                            E[] rest)

Returns an unmodifiable list containing the specified first element and the additional elements.
