public final void add(int index,
                      double element)
```
    Description copied from interface: DoubleList
    
    Inserts the specified element at the specified position (optional operation). Shifts the element currently at that position (if any) and any subsequent elements to the right, increasing their indices.
    
    Specified by:
    
    add in interface DoubleList
    
    Parameters:
    
    index - the index at which to insert the element
    
    element - the value to insert
  - addAll
```
public final boolean addAll(int index,
                            DoubleCollection collection)
```
    Description copied from interface: DoubleList
    
    Inserts all of the elements in the specified collection into me, at the specified position (optional operation). Shifts the element currently at that position (if any) and any subsequent elements to the right, increasing their indices. The new elements will appear in the order that they are returned by the given collection's iterator.
    
    Specified by:
    
    addAll in interface DoubleList
    
    Parameters:
    
    index - the index at which to insert the first element from the specified collection
    
    collection - the DoubleCollection of elements to add
    
    Returns:
    
    true iff I changed as a result of this call
  - removeElementAt
```
public final double removeElementAt(int index)
```
    Description copied from interface: DoubleList
    
    Removes the element at the specified position in (optional operation). Any subsequent elements are shifted to the left, subtracting one from their indices. Returns the element that was removed.
    
    Specified by:
    
    removeElementAt in interface DoubleList
    
    Parameters:
    
    index - the index of the element to remove
    
    Returns:
    
    the value of the element that was removed
  - set
```
public final double set(int index,
                        double element)
```
    Description copied from interface: DoubleList
    
    Replaces the element at the specified position in me with the specified element (optional operation).
    
    Specified by:
    
    set in interface DoubleList
    
    Parameters:
    
    index - the index of the element to change
    
    element - the value to be stored at the specified position
    
    Returns:
    
    the value previously stored at the specified position
  - add
```
public final boolean add(double element)
```
    Description copied from interface: DoubleCollection
    
    Ensures that I contain the specified element (optional operation). Returns true iff I changed as a result of this call.
    If a collection refuses to add the specified element for any reason other than that it already contains the element, it must throw an exception (rather than simply returning false). This preserves the invariant that a collection always contains the specified element after this call returns.
    
    Specified by:
    
    add in interface DoubleCollection
    
    Specified by:
    
    add in interface DoubleList
    
    Parameters:
    
    element - the value whose presence within me is to be ensured
    
    Returns:
    
    true iff I changed as a result of this call
  - addAll
```
public final boolean addAll(DoubleCollection c)
```
    Description copied from interface: DoubleCollection
    
    Adds all of the elements in the specified collection to me (optional operation).
    
    Specified by:
    
    addAll in interface DoubleCollection
    
    Parameters:
    
    c - the collection of elements whose presence within me is to be ensured
    
    Returns:
    
    true iff I changed as a result of this call
  - clear
```
public final void clear()
```
    Description copied from interface: DoubleCollection
    
    Removes all my elements (optional operation). I will be empty after this method successfully returns.
    
    Specified by:
    
    clear in interface DoubleCollection
  - removeAll
```
public final boolean removeAll(DoubleCollection c)
```
    Description copied from interface: DoubleCollection
    
    Removes all of my elements that are contained in the specified collection (optional operation). The behavior of this method is unspecified if the given collection is modified while this method is executing. Note that this includes the case in which the given collection is this collection, and it is not empty.
    
    Specified by:
    
    removeAll in interface DoubleCollection
    
    Parameters:
    
    c - the collection of elements to remove
    
    Returns:
    
    true iff I contained the at least one of the specified elements, in other words, returns true iff I changed as a result of this call
  - removeElement
```
public final boolean removeElement(double element)
```
    Description copied from interface: DoubleCollection
    
    Removes a single occurrence of the specified element (optional operation).
    
    Specified by:
    
    removeElement in interface DoubleCollection
    
    Parameters:
    
    element - the element to remove, if present
    
    Returns:
    
    true iff I contained the specified element, in other words, iff I changed as a result of this call
  - retainAll
```
public final boolean retainAll(DoubleCollection c)
```
    Description copied from interface: DoubleCollection
    
    Removes all of my elements that are not contained in the specified collection (optional operation). (In other words, retains only my elements that are contained in the specified collection.) The behavior of this method is unspecified if the given collection is modified while this method is executing.
    
    Specified by:
    
    retainAll in interface DoubleCollection
    
    Parameters:
    
    c - the collection of elements to retain
    
    Returns:
    
    true iff I changed as a result of this call
  - subList
```
public final DoubleList subList(int fromIndex,
                                int toIndex)
```
    Description copied from interface: DoubleList
    
    Returns a view of the elements within me between the specified fromIndex, inclusive, and toIndex, exclusive. The returned DoubleList is backed by me, so that any changes in the returned list are reflected in me, and vice-versa. The returned list supports all of the optional operations that I support.
    Note that when fromIndex == toIndex, the returned list is initially empty, and when fromIndex == 0 && toIndex == size() the returned list is my "improper" sublist, containing all my elements.
    The semantics of the returned list become undefined if I am structurally modified in any way other than via the returned list.
    
    Specified by:
    
    subList in interface DoubleList
    
    Parameters:
    
    fromIndex - the smallest index (inclusive) in me that appears in the returned list
    
    toIndex - the largest index (exclusive) in me that appears in the returned list
    
    Returns:
    
    a view of this list from fromIndex (inclusive) to toIndex (exclusive)
  - iterator
```
public final DoubleIterator iterator()
```
    Description copied from interface: DoubleCollection
    
    Returns an iterator over all my elements. This base interface places no constraints on the order in which the elements are returned by the returned iterator.
    
    Specified by:
    
    iterator in interface DoubleCollection
    
    Specified by:
    
    iterator in interface DoubleList
    
    Returns:
    
    an iterator over all my elements.

```
public DoubleListIterator listIterator(int index)
```
    Description copied from interface: DoubleList
    
    Returns a bidirectional iterator over all my elements, in the appropriate sequence, starting at the specified position. The specified index indicates the first element that would be returned by an initial call to the next method. An initial call to the previous method would return the element with the specified index minus one.
