    add

    public boolean add(Object o)
    Appends the specified element to the end of this list (optional operation).

    Lists that support this operation may place limitations on what elements may be added to this list. In particular, some lists will refuse to add null elements, and others will impose restrictions on the type of elements that may be added. List classes should clearly specify in their documentation any restrictions on what elements may be added.

    Specified by:
    add in interface Collection
    Parameters:
    o - element to be appended to this list.
    Returns:
    true (as per the general contract of the Collection.add method).
    Throws:
    UnsupportedOperationException - if the add method is not supported by this list.
    ClassCastException - if the class of the specified element prevents it from being added to this list.
    NullPointerException - if the specified element is null and this list does not support null elements.
    IllegalArgumentException - if some aspect of this element prevents it from being added to this list.

    remove

    public boolean remove(Object o)
    Removes the first occurrence in this list of the specified element (optional operation). If this list does not contain the element, it is unchanged. More formally, removes the element with the lowest index i such that (o==null ? get(i)==null : o.equals(get(i))) (if such an element exists).

    Specified by:
    remove in interface Collection
    Parameters:
    o - element to be removed from this list, if present.

    addAll

    public boolean addAll(Collection c)
    Appends all of the elements in the specified collection to the end of this list, in the order that they are returned by the specified collection's iterator (optional operation). The behavior of this operation is unspecified if the specified collection is modified while the operation is in progress. (Note that this will occur if the specified collection is this list, and it's nonempty.)

    Specified by:
    addAll in interface Collection
    Parameters:
    c - collection whose elements are to be added to this list.
    Returns:
    true if this list changed as a result of the call.

    addAll

    public boolean addAll(int index,
                          Collection c)
    Inserts all of the elements in the specified collection into this list at the specified position (optional operation). Shifts the element currently at that position (if any) and any subsequent elements to the right (increases their indices). The new elements will appear in this list in the order that they are returned by the specified collection's iterator. The behavior of this operation is unspecified if the specified collection is modified while the operation is in progress. (Note that this will occur if the specified collection is this list, and it's nonempty.)

    Parameters:
    index - index at which to insert first element from the specified collection.
    c - elements to be inserted into this list.
    Returns:
    true if this list changed as a result of the call.
    Throws:
    UnsupportedOperationException - if the addAll method is not supported by this list.
    ClassCastException - if the class of one of elements of the specified collection prevents it from being added to this list.
    NullPointerException - if the specified collection contains one or more null elements and this list does not support null elements, or if the specified collection is null.
    IllegalArgumentException - if some aspect of one of elements of the specified collection prevents it from being added to this list.
    IndexOutOfBoundsException - if the index is out of range (index < 0 || index > size()).

    removeAll

    public boolean removeAll(Collection c)
    Removes from this list all the elements that are contained in the specified collection (optional operation).

    Specified by:
    removeAll in interface Collection
    Parameters:
    c - collection that defines which elements will be removed from this list.
    Returns:
    true if this list changed as a result of the call.
    Throws:
    UnsupportedOperationException - if the removeAll method is not supported by this list.
    ClassCastException - if the types of one or more elements in this list are incompatible with the specified collection (optional).
    NullPointerException - if this list contains one or more null elements and the specified collection does not support null elements (optional).
    NullPointerException - if the specified collection is null.
    See Also:
    remove(Object), contains(Object)

    retainAll

    public boolean retainAll(Collection c)
    Retains only the elements in this list that are contained in the specified collection (optional operation). In other words, removes from this list all the elements that are not contained in the specified collection.

    Specified by:
    retainAll in interface Collection
    Parameters:
    c - collection that defines which elements this set will retain.
    Returns:
    true if this list changed as a result of the call.
    Throws:
    UnsupportedOperationException - if the retainAll method is not supported by this list.
    ClassCastException - if the types of one or more elements in this list are incompatible with the specified collection (optional).
    NullPointerException - if this list contains one or more null elements and the specified collection does not support null elements (optional).
    NullPointerException - if the specified collection is null.
    See Also:
    remove(Object), contains(Object)

    clear

    public void clear()
    Removes all of the elements from this list (optional operation). This list will be empty after this call returns (unless it throws an exception).

    Specified by:
    clear in interface Collection
    Throws:
    UnsupportedOperationException - if the clear method is not supported by this list.

    equals

    public boolean equals(Object o)
    Compares the specified object with this list for equality. Returns true if and only if the specified object is also a list, both lists have the same size, and all corresponding pairs of elements in the two lists are equal. (Two elements e1 and e2 are equal if (e1==null ? e2==null : e1.equals(e2)).) In other words, two lists are defined to be equal if they contain the same elements in the same order. This definition ensures that the equals method works properly across different implementations of the List interface.

    Specified by:
    equals in interface Collection
    Overrides:
    equals in class Object
    Parameters:
    o - the object to be compared for equality with this list.
    Returns:
    true if the specified object is equal to this list.
    See Also:
    Object.hashCode(), Hashtable

    hashCode

    public int hashCode()
    Returns the hash code value for this list. The hash code of a list is defined to be the result of the following calculation:
      hashCode = 1;
      Iterator i = list.iterator();
      while (i.hasNext()) {
          Object obj = i.next();
          hashCode = 31*hashCode + (obj==null ? 0 : obj.hashCode());
      }
     
    This ensures that list1.equals(list2) implies that list1.hashCode()==list2.hashCode() for any two lists, list1 and list2, as required by the general contract of Object.hashCode.

    Specified by:
    hashCode in interface Collection
    Overrides:
    hashCode in class Object
    Returns:
    the hash code value for this list.
    See Also:
    Object.hashCode(), Object.equals(Object), equals(Object)

    Parameters:
    index - index of element to return.
    Returns:
    the element at the specified position in this list.
    Throws:
    IndexOutOfBoundsException - if the index is out of range (index < 0 || index >= size()).

    set

    public Object set(int index,
                      Object element)
    Replaces the element at the specified position in this list with the specified element (optional operation).

    Returns:
    the element previously at the specified position.
    Throws:
    UnsupportedOperationException - if the set method is not supported by this list.
    ClassCastException - if the class of the specified element prevents it from being added to this list.
    NullPointerException - if the specified element is null and this list does not support null elements.
    IllegalArgumentException - if some aspect of the specified element prevents it from being added to this list.
    IndexOutOfBoundsException - if the index is out of range (index < 0 || index >= size()).

    add

    public void add(int index,
                    Object element)
    Inserts the specified element at the specified position in this list (optional operation). Shifts the element currently at that position (if any) and any subsequent elements to the right (adds one to their indices).

    Parameters:
    index - index at which the specified element is to be inserted.
    element - element to be inserted.
    Throws:
    UnsupportedOperationException - if the add method is not supported by this list.
    ClassCastException - if the class of the specified element prevents it from being added to this list.
    NullPointerException - if the specified element is null and this list does not support null elements.
    IllegalArgumentException - if some aspect of the specified element prevents it from being added to this list.
    IndexOutOfBoundsException - if the index is out of range (index < 0 || index > size()).

    remove

    public Object remove(int index)
    Removes the element at the specified position in this list (optional operation). Shifts any subsequent elements to the left (subtracts one from their indices). Returns the element that was removed from the list.

    Parameters:
    index - the index of the element to removed.
    Returns:
    the element previously at the specified position.
    Throws:
    UnsupportedOperationException - if the remove method is not supported by this list.
    IndexOutOfBoundsException - if the index is out of range (index < 0 || index >= size()).

    indexOf

    public int indexOf(Object o)
    Returns the index in this list of the first occurrence of the specified element, or -1 if this list does not contain this element. More formally, returns the lowest index i such that (o==null ? get(i)==null : o.equals(get(i))), or -1 if there is no such index.

    Parameters:
    o - element to search for.
    Returns:
    the index in this list of the first occurrence of the specified element, or -1 if this list does not contain this element.
    Throws:
    ClassCastException - if the type of the specified element is incompatible with this list (optional).
    NullPointerException - if the specified element is null and this list does not support null elements (optional).

    lastIndexOf

    public int lastIndexOf(Object o)
    Returns the index in this list of the last occurrence of the specified element, or -1 if this list does not contain this element. More formally, returns the highest index i such that (o==null ? get(i)==null : o.equals(get(i))), or -1 if there is no such index.

    Parameters:
    o - element to search for.
    Returns:
    the index in this list of the last occurrence of the specified element, or -1 if this list does not contain this element.
    Throws:
    ClassCastException - if the type of the specified element is incompatible with this list (optional).
    NullPointerException - if the specified element is null and this list does not support null elements (optional).

    listIterator

    public ListIterator listIterator()
    Returns a list iterator of the elements in this list (in proper sequence).

    Returns:
    a list iterator of the elements in this list (in proper sequence).

    listIterator

    public ListIterator listIterator(int index)
    Returns a list iterator of the elements in this list (in proper sequence), starting at the specified position in this list. 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.

    Parameters:
    index - index of first element to be returned from the list iterator (by a call to the next method).
    Returns:
    a list iterator of the elements in this list (in proper sequence), starting at the specified position in this list.
    Throws:
    IndexOutOfBoundsException - if the index is out of range (index < 0 || index > size()).

    subList

    public List subList(int fromIndex,
                        int toIndex)
    Returns a view of the portion of this list between the specified fromIndex, inclusive, and toIndex, exclusive. (If fromIndex and toIndex are equal, the returned list is empty.) The returned list is backed by this list, so non-structural changes in the returned list are reflected in this list, and vice-versa. The returned list supports all of the optional list operations supported by this list.

    This method eliminates the need for explicit range operations (of the sort that commonly exist for arrays). Any operation that expects a list can be used as a range operation by passing a subList view instead of a whole list. For example, the following idiom removes a range of elements from a list:

    	    list.subList(from, to).clear();
     
    Similar idioms may be constructed for indexOf and lastIndexOf, and all of the algorithms in the Collections class can be applied to a subList.

    The semantics of the list returned by this method become undefined if the backing list (i.e., this list) is structurally modified in any way other than via the returned list. (Structural modifications are those that change the size of this list, or otherwise perturb it in such a fashion that iterations in progress may yield incorrect results.)

    Parameters:
    fromIndex - low endpoint (inclusive) of the subList.
    toIndex - high endpoint (exclusive) of the subList.
    Returns:
    a view of the specified range within this list.
    Throws:
    IndexOutOfBoundsException - for an illegal endpoint index value (fromIndex < 0 || toIndex > size || fromIndex > toIndex).
