Constructs an empty list with the specified initial capacity.

Parameters:

initialCapacity - the initial capacity of the list.

Throws:

java.lang.IllegalArgumentException - if the specified initial capacity is negative

SortedArrayList

public SortedArrayList()

Constructs an empty list with an initial capacity of ten.

SortedArrayList

public SortedArrayList(java.util.Collection c)

Constructs a list containing the elements of the specified collection, in the order they are returned by the collection's iterator. The SortedArrayList instance has an initial capacity of 110% the size of the specified collection.

Returns:

the number of elements in this list.

isEmpty

public boolean isEmpty()

Tests if this list has no elements.

Specified by:

isEmpty in interface java.util.Collection

Specified by:

isEmpty in interface java.util.List

Overrides:

isEmpty in class java.util.AbstractCollection

Returns:

true if this list has no elements; false otherwise.

contains

public boolean contains(java.lang.Object elem)

Returns true if this list contains the specified element.

Specified by:

contains in interface java.util.Collection

Specified by:

contains in interface java.util.List

Overrides:

contains in class java.util.AbstractCollection

Parameters:

elem - element whose presence in this List is to be tested.

Returns:

true if the specified element is present; false otherwise.

indexOf

public int indexOf(java.lang.Object elem)

Searches for the first occurence of the given argument, testing for equality using the equals method.

Specified by:

indexOf in interface java.util.List

Overrides:

indexOf in class java.util.AbstractList

Parameters:

elem - an object.

Returns:

the index of the first occurrence of the argument in this list; returns -1 if the object is not found.

See Also:

Object.equals(Object)

lastIndexOf

public int lastIndexOf(java.lang.Object elem)

Returns the index of the last occurrence of the specified object in this list.

Specified by:

lastIndexOf in interface java.util.List

Overrides:

lastIndexOf in class java.util.AbstractList

Parameters:

elem - the desired element.

Returns:

the index of the last occurrence of the specified object in this list; returns -1 if the object is not found.

clone

public java.lang.Object clone()

Returns a shallow copy of this SortedArrayList instance. (The elements themselves are not copied.)

Overrides:

clone in class java.lang.Object

Returns:

a clone of this SortedArrayList instance.

toArray

public java.lang.Object[] toArray()

Returns an array containing all of the elements in this list in the correct order.

Specified by:

toArray in interface java.util.Collection

Specified by:

toArray in interface java.util.List

Overrides:

toArray in class java.util.AbstractCollection

Returns:

an array containing all of the elements in this list in the correct order.

toArray

public java.lang.Object[] toArray(java.lang.Object[] a)

Returns an array containing all of the elements in this list in the correct order; the runtime type of the returned array is that of the specified array. If the list fits in the specified array, it is returned therein. Otherwise, a new array is allocated with the runtime type of the specified array and the size of this list.

If the list fits in the specified array with room to spare (i.e., the array has more elements than the list), the element in the array immediately following the end of the collection is set to null. This is useful in determining the length of the list only if the caller knows that the list does not contain any null elements.

Specified by:

toArray in interface java.util.Collection

Specified by:

toArray in interface java.util.List

Overrides:

toArray in class java.util.AbstractCollection

Parameters:

a - the array into which the elements of the list are to be stored, if it is big enough; otherwise, a new array of the same runtime type is allocated for this purpose.

Returns:

an array containing the elements of the list.

Throws:

java.lang.ArrayStoreException - if the runtime type of a is not a supertype of the runtime type of every element in this list.

get

public java.lang.Object get(int index)

Returns the element at the specified position in this list.

Specified by:

get in interface java.util.List

Specified by:

get in class java.util.AbstractList

Parameters:

index - index of element to return.

Returns:

the element at the specified position in this list.

Throws:

java.lang.IndexOutOfBoundsException - if index is out of range (index < 0 || index >= size()).

set

public java.lang.Object set(int index,
                            java.lang.Object element)

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

Returns:

the element previously at the specified position.

Throws:

java.lang.IndexOutOfBoundsException - if index out of range (index < 0 || index >= size()).

public boolean add(java.lang.Object o)

Appends the specified element to the end of this list.

Specified by:

add in interface java.util.Collection

Specified by:

add in interface java.util.List

Overrides:

public boolean add(java.lang.Object[] o)

Appends the specified element to the end of this list.

Parameters:

o - array element to be appended to this list.

Returns:

true (as per the general contract of Collection.add).

public boolean add(java.util.List list)

add

public void add(int index,
                java.lang.Object 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).

Specified by:

Overrides:

add in class java.util.AbstractList

Parameters:

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

Removes the element at the specified position in this list. Shifts any subsequent elements to the left (subtracts one from their indices).

Specified by:

remove in interface java.util.List

Overrides:

remove in class java.util.AbstractList

Parameters:

index - the index of the element to removed.

Returns:

the element that was removed from the list.

Throws:

clear in class java.util.AbstractList

addAll

public boolean addAll(java.util.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. 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.)

Specified by:

addAll in interface java.util.Collection

Specified by:

addAll in interface java.util.List

Overrides:

addAll in class java.util.AbstractCollection

Parameters:

c - the elements to be inserted into this list.

Returns:

true if this list changed as a result of the call.

Throws:

java.lang.IndexOutOfBoundsException - if index out of range (index < 0 || index > size()).

java.lang.NullPointerException - if the specified collection is null.

addAll

public boolean addAll(int index,
                      java.util.Collection 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.

Specified by:

addAll in interface java.util.List

Overrides:

addAll in class java.util.AbstractList

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.

Overrides:

removeRange in class java.util.AbstractList

Parameters:

fromIndex - index of first element to be removed.

toIndex - index after last element to be removed.
