Method

ArrayListnewArrayList(Iterable iterable)
new Array List 
if (iterable == null) {
    throw new NullPointerException();
ArrayList<E> list = new ArrayList<E>();
for (Iterator<E> i = iterable.iterator(); i.hasNext();) {
    list.add(i.next());
return list;
...
ListnewArrayList(T anObj)
Creates a new array list with given object. 
return newArrayList(10, anObj);
ListnewArrayList(T... elements)
Avoid dependency on Guava types 
List<T> list = new ArrayList<>(1);
Collections.addAll(list, elements);
return list;
ListnewArrayList(T... items)
new Array List 
List<T> list = new ArrayList<T>();
for (T t : items) {
    list.add(t);
return list;
ListnewArrayList(T... objectList)
new Array List 
List<T> list = new ArrayList<T>(objectList.length);
for (T obj : objectList) {
    list.add(obj);
return list;
ListnewArrayList(T... objs)
Returns the value mapped by key, or if no mapping exists, puts to map and returns the value supplied by valueSupplier. 
List<T> results = new ArrayList<T>();
results.addAll(Arrays.asList(objs));
return results;
ListnewArrayList(X... args)
new Array List 
return Arrays.asList(args);
ListnewArrayListOnNull(List list)
new Array List On Null 
if (list == null) {
    list = new ArrayList<T>();
return list;
ArrayListnewArrayListSized(Iterable fromSize)
Creates a new ArrayList which if possible is sized the same as the passed in iterable (ie only if it is actually a Collection). 
if (fromSize instanceof Collection<?>)
    return new ArrayList<T>(((Collection<?>) fromSize).size());
else
    return new ArrayList<T>();
ArrayListnewArrayListWithCapacity(int initSize)
new Array List With Capacity 
return new ArrayList<T>(initSize);
