Class Overview | This Package | All Packages

Fields
Name Description
capacityIncrement The amount by which the capacity of the vector is automatically incremented when its size becomes greater than its capacity.
elementCount The number of valid components in the vector.
elementData The array buffer into which the components of the vector are stored.

Constructors
Name Description
Vector() Constructs an empty vector.
Vector(int) Constructs an empty vector with the specified initial capacity.
Vector(int, int) Constructs an empty vector with the specified initial capacity and capacity increment.

Methods
Name Description
addElement(Object) Adds the specified component to the end of this vector, increasing its size by one.
capacity() Returns the current capacity of this vector.
clone() Returns a clone of this vector.
contains(Object) Tests if the specified object is a component in this vector.
copyInto(Object[]) Copies the components of this vector into the specified array.
elementAt(int) Returns the component at the specified index.
elements() Returns an enumeration of the components of this vector.
ensureCapacity(int) 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.
firstElement() Returns the first component of this vector.
indexOf(Object) Searches for the first occurence of the given argument, testing for equality using the equals method.
indexOf(Object, int) Searches for the first occurence of the given argument, beginning the search at index, and testing for equality using the equals method.
insertElementAt(Object, int) Inserts the specified object as a component in this vector at the specified index.
isEmpty() Tests if this vector has no components.
lastElement() Returns the last component of the vector.
lastIndexOf(Object) Returns the index of the last occurrence of the specified object in this vector.
lastIndexOf(Object, int) Searches backwards for the specified object, starting from the specified index, and returns an index to it.
removeAllElements() Removes all components from this vector and sets its size to zero.
removeElement(Object) Removes the first occurrence of the argument from this vector.
removeElementAt(int) Deletes the component at the specified index.
setElementAt(Object, int) Sets the component at the specified index of this vector to be the specified object.
setSize(int) Sets the size of this vector.
size() Returns the number of components in this vector.
toString() Returns a string representation of this vector.
trimToSize() Trims the capacity of this vector to be the vector's current size.
