Vector class Methods in Java Part -II

java.util.Vector

The Vector class implements a growable array of objects. Like an array, it contains components that can be accessed using an integer index. However, the size of a Vector can grow or shrink as needed to accommodate adding and removing items after the Vector has been created.

Some methods of Vector class.

hashCode(): This method returns the hash code value for this Vector.

indexOf(Object): This method returns the index of the first occurrence of the specified element in this vector, or -1 if this vector does not contain the element.

indexOf(Object, int): This method returns the index of the first occurrence of the specified element in this vector, searching forwards from the index or returns -1 if the element is not found.

insertElementAt(K, int): This method inserts the specified object as a component in this vector at the specified index.

isEmpty(): This method tests if this vector has no components.

iterator(): This method returns an iterator over the elements in this list in proper sequence.

lastElement(): This method returns the last component of the vector.

lastIndexOf(Object): This method returns the index of the last occurrence of the specified element in this vector, or -1 if this vector does not contain the element.

lastIndexOf(Object, int): This method returns the index of the last occurrence of the specified element in this vector, searching backward from the index, or returns -1 if the element is not found.

listIterator(): This method returns a list iterator over the elements in this list.

listIterator(int): This method returns a list iterator over the elements in this list starting at the specified position in the list.

remove(int): This method removes the element at the specified position in this Vector. Shifts any subsequent elements to the left (subtracts one from their indices).

remove(Object): This method removes the first occurrence of the specified element in this Vector. If the Vector does not contain the element, it is unchanged.

removeAll(Collection): This method removes from this Vector all of its elements that are contained in the specified Collection.

removeAllElements(): This method removes all components from this vector and sets its size to zero.

removeElement(Object): This method removes the first (lowest-indexed) occurrence of the argument from this vector.

removeElementAt(int): This method deletes the component at the specified index.

removeIf(Predicate): This method removes all of the elements of this collection that satisfy the given predicate.
