public final int lastIndexOf(Object elem, int index)

throws IndexOutOfBoundsException;

}

21.11.1

protected Object[] elementData;

Internally, a

Vector

 keeps its elements in an array that is at least large enough to

contain all the elements.

21.11.2

protected int elementCount;

This field holds the number of items currently in this

Vector

 object. Components

elementData[0]

 through

elementData[elementCount 1]

 are the actual items.

21.11.3

protected int capacityIncrement;

When the method

ensureCapacity

 ( 21.11.22) must increase the size of the data

array in the field

elementData

 (by creating a new array), it increases the size by

at least the amount in

capacityIncrement

; but if

capacityIncrement

 is zero,

then it at least doubles the size of the data array.

21.11.4

public Vector(int initialCapacity, int capacityIncrement)

This constructor initializes a newly created

Vector

 so that its internal data array

has size

initialCapacity

 and its standard capacity increment is the value of

capacityIncrement

. Initially, the

Vector

 contains no items.

21.11.5

public Vector(int initialCapacity)

This constructor initializes a newly created

Vector

 so that its internal data array

has size

initialCapacity

 and its standard capacity increment is zero. Initially,

the

Vector

 contains no items.

21.11.6

public Vector()

This constructor initializes a newly created

Vector

 so that its internal data array

has size

10

 and its standard capacity increment is zero. Initially the

Vector

 con 

tains no items.
