Constructor

	Vector() Constructs an empty vector so that its internal data array has size 10 and its standard capacity increment is zero.
	Vector(int initialCapacity) Constructs an empty vector with the specified initial capacity and with its capacity increment equal to zero.
	Vector(Collection c) Constructs a vector containing the elements of the specified collection, in the order they are returned by the collection's iterator.
	Vector(int initialCapacity, int capacityIncrement) Constructs an empty vector with the specified initial capacity and capacity increment.

Method

boolean	add(E e) Appends the specified element to the end of this Vector.
void	add(int index, E element) Inserts the specified element at the specified position in this Vector.
boolean	addAll(Collection c) Appends all of the elements in the specified Collection to the end of this Vector, in the order that they are returned by the specified Collection's Iterator.
boolean	addAll(int index, Collection c) Inserts all of the elements in the specified Collection into this Vector at the specified position.
void	addElement(E obj) Adds the specified component to the end of this vector, increasing its size by one.
int	capacity() Returns the current capacity of this vector.
void	clear() Removes all of the elements from this Vector.
Object	clone() Returns a clone of this vector.
boolean	contains(Object o) Returns true if this vector contains the specified element.
boolean	containsAll(Collection c) Returns true if this Vector contains all of the elements in the specified Collection.
void	copyInto(Object[] anArray) Copies the components of this vector into the specified array.
E	elementAt(int index) Returns the component at the specified index.
Enumeration	elements() Returns an enumeration of the components of this vector.
void	ensureCapacity(int minCapacity) Increases the capacity of this vector, if necessary, to ensure that it can hold at least the number of components specified by the minimum capacity argument.
boolean	equals(Object o) Compares the specified Object with this Vector for equality.
E	firstElement() Returns the first component (the item at index 0 ) of this vector.
void	forEach(Consumer action)
E	get(int index) Returns the element at the specified position in this Vector.
Class	getClass() Returns the runtime class of this Object .
int	hashCode() Returns the hash code value for this Vector.
int	indexOf(Object o) Returns the index of the first occurrence of the specified element in this vector, or -1 if this vector does not contain the element.
int	indexOf(Object o, int index) Returns the index of the first occurrence of the specified element in this vector, searching forwards from index , or returns -1 if the element is not found.
void	insertElementAt(E obj, int index) Inserts the specified object as a component in this vector at the specified index .
boolean	isEmpty() Tests if this vector has no components.
Iterator	iterator() Returns an iterator over the elements in this list in proper sequence.
E	lastElement() Returns the last component of the vector.
int	lastIndexOf(Object o) Returns the index of the last occurrence of the specified element in this vector, or -1 if this vector does not contain the element.
int	lastIndexOf(Object o, int index) Returns the index of the last occurrence of the specified element in this vector, searching backwards from index , or returns -1 if the element is not found.
ListIterator	listIterator() Returns a list iterator over the elements in this list (in proper sequence).
ListIterator	listIterator(int index) Returns a list iterator over the elements in this list (in proper sequence), starting at the specified position in the list.
boolean	remove(Object o) Removes the first occurrence of the specified element in this Vector If the Vector does not contain the element, it is unchanged.
E	remove(int index) Removes the element at the specified position in this Vector.
boolean	removeAll(Collection c) Removes from this Vector all of its elements that are contained in the specified Collection.
void	removeAllElements() Removes all components from this vector and sets its size to zero.
boolean	removeElement(Object obj) Removes the first (lowest-indexed) occurrence of the argument from this vector.
void	removeElementAt(int index) Deletes the component at the specified index.
boolean	retainAll(Collection c) Retains only the elements in this Vector that are contained in the specified Collection.
E	set(int index, E element) Replaces the element at the specified position in this Vector with the specified element.
void	setElementAt(E obj, int index) Sets the component at the specified index of this vector to be the specified object.
void	setSize(int newSize) Sets the size of this vector.
int	size() Returns the number of components in this vector.
Stream	stream() Returns a sequential Stream with this collection as its source.
List	subList(int fromIndex, int toIndex) Returns a view of the portion of this List between fromIndex, inclusive, and toIndex, exclusive.
Object[]	toArray() Returns an array containing all of the elements in this Vector in the correct order.
T[]	toArray(T[] a) Returns an array containing all of the elements in this Vector in the correct order; the runtime type of the returned array is that of the specified array.
String	toString() Returns a string representation of this Vector, containing the String representation of each element.
void	trimToSize() Trims the capacity of this vector to be the vector's current size.
