Stack
Fields
protected int
The amount by which the capacity of the vector is automatically incremented when its size becomes greater than its capacity.
protected int
The number of valid components in this Vector object.
The array buffer into which the components of the vector are stored.
Constructors
Constructs an empty vector so that its internal data array has size 10 and its standard capacity increment is zero.
Constructs an empty vector with the specified initial capacity and with its capacity increment equal to zero.
Vector(int initialCapacity, int capacityIncrement)
Constructs an empty vector with the specified initial capacity and capacity increment.
Constructs a vector containing the elements of the specified collection, in the order they are returned by the collection's iterator.
void
add(int index, E element)

boolean
Appends the specified element to the end of this Vector.
boolean
Inserts all of the elements in the specified Collection into this Vector at the specified position.
boolean
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.
void
Adds the specified component to the end of this vector, increasing its size by one.
int
Returns the current capacity of this vector.
void
Removes all of the elements from this Vector.
Returns a clone of this vector.
boolean
Returns true if this vector contains the specified element.
boolean
Returns true if this Vector contains all of the elements in the specified Collection.
void
Copies the components of this vector into the specified array.
Returns the component at the specified index.
Returns an enumeration of the components of this vector.
void
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
Compares the specified Object with this Vector for equality.
Returns the first component (the item at index 0) of this vector.
void
Performs the given action for each element of the Iterable until all elements have been processed or the action throws an exception.
Returns the element at the specified position in this Vector.
int
Returns the hash code value for this Vector.
int
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
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
Inserts the specified object as a component in this vector at the specified index.
boolean
Tests if this vector has no components.
Returns an iterator over the elements in this list in proper sequence.
Returns the last component of the vector.
int
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
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.
Returns a list iterator over the elements in this list (in proper sequence).
Returns a list iterator over the elements in this list (in proper sequence), starting at the specified position in the list.
Removes the element at the specified position in this Vector.
boolean
Removes the first occurrence of the specified element in this Vector If the Vector does not contain the element, it is unchanged.
boolean
Removes from this Vector all of its elements that are contained in the specified Collection.
void
Removes all components from this vector and sets its size to zero.
boolean
Removes the first (lowest-indexed) occurrence of the argument from this vector.
void
Deletes the component at the specified index.
boolean
Removes all of the elements of this collection that satisfy the given predicate (optional operation).
protected void
Removes from this list all of the elements whose index is between fromIndex, inclusive, and toIndex, exclusive.
void
Replaces each element of this list with the result of applying the operator to that element (optional operation).
boolean
Retains only the elements in this Vector that are contained in the specified Collection.
set(int index, E element)
Replaces the element at the specified position in this Vector with the specified element.
void
Sets the component at the specified index of this vector to be the specified object.
void
Sets the size of this vector.
int
Returns the number of components in this vector.
subList(int fromIndex, int toIndex)
Returns a view of the portion of this List between fromIndex, inclusive, and toIndex, exclusive.
Returns an array containing all of the elements in this Vector in the correct order.
<T> T[]
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.
Returns a string representation of this Vector, containing the String representation of each element.
void
Trims the capacity of this vector to be the vector's current size.
