Lists.newArrayList vs new ArrayList

The guava builder saves typing the type arguments multiple times. Compare:

List<Foo<Bar, Baz>> list = Lists.newArrayList();
List<Foo<Bar, Baz>> list = new ArrayList<Foo<Bar, Baz>>();

In Java 7 it's a bit obsolete though, because you have the diamond operator:

List<Foo<Bar, Baz>> list = new ArrayList<>();

From Guava's source:

public static <E> ArrayList<E> newArrayList() {
    return new ArrayList<E>();
}

All that's doing is allowing for type inference - no difference at runtime.

Add one point, overloading version of Lists.newArrayList() is more useful:

provide more useful functions than new ArrayList().

For example: new ArrayList() cannot do:

Lists.newArrayList("a","b");
Lists.newArrayList(anIterable);
