Constructor Detail

OverrideList

public OverrideList()

Constructs an empty list with an initial capacity of ten.

OverrideList

public OverrideList(int initialCapacity)

Constructs an empty list with the specified initial capacity.

Parameters:

initialCapacity - the initial capacity of the list

Throws:

IllegalArgumentException - if the specified initial capacity is negative

OverrideList

public OverrideList(Collection<? extends E> c)

Constructs a list containing the elements of the specified collection, in the order they are returned by the collection's iterator.

Parameters:

c - the collection whose elements are to be placed into this list

Throws:

NullPointerException - if the specified collection is null

Method Detail

set

public E set(int index,
             E element)

Replaces the element at the specified position in this list with the specified element.

Specified by:

set in interface List<E>

Overrides:

set in class ArrayList<E>

Parameters:

index - index of the element to replace

element - element to be stored at the specified position

Returns:

the element previously at the specified position

Throws:

IndexOutOfBoundsException

add

public boolean add(E e)

Appends the specified element to the end of this list. if the element is exist override old element.

Specified by:

add in interface Collection<E>

Specified by:

add in interface List<E>

Overrides:

add in class ArrayList<E>

Parameters:

e - element to be appended to this list

Returns:

true (as specified by Collection.add(E))

add

public void add(int index,
                E element)

Inserts the specified element at the specified position in this list. Shifts the element currently at that position (if any) and any subsequent elements to the right (adds one to their indices). if the element is exist no processing any more

Specified by:

add in interface List<E>

Overrides:

add in class ArrayList<E>

Parameters:

index - index at which the specified element is to be inserted

element - element to be inserted

Throws:

IndexOutOfBoundsException

addAll

public boolean addAll(Collection<? extends E> 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. The behavior of this operation is undefined if the specified collection is modified while the operation is in progress. (This implies that the behavior of this call is undefined if the specified collection is this list, and this list is nonempty.) if the element is exist override old element.

Specified by:

addAll in interface Collection<E>

Specified by:

addAll in interface List<E>

Overrides:

addAll in class ArrayList<E>

Parameters:

c - collection containing elements to be added to this list

Returns:

true if this list changed as a result of the call

Throws:

NullPointerException - if the specified collection is null

addAll

public boolean addAll(int index,
                      Collection<? extends E> c)

Inserts all of the elements in the specified collection into this list, starting at the specified position. 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 the list in the order that they are returned by the specified collection's iterator. remove all existed elements

Specified by:

addAll in interface List<E>

Overrides:

addAll in class ArrayList<E>

Parameters:

index - index at which to insert the first element from the specified collection

c - collection containing elements to be added to this list

Returns:

true if this list changed as a result of the call

Throws:

IndexOutOfBoundsException

NullPointerException - if the specified collection is null
