Answer Posted / rama krishna dwadasi
VECTOR:
i)Vector is a legacy class and represents array data structure.
ii)Vector uses indexing notation to store values.
iii)Vector can grow and shrink dynamically.
iv)Vector is synchronized; multiple threads cannot access
the vector object concurrently. Only one thread can access
the Vector object at a specific time.
v)Duplicate values are allowed.
vi)Before to java 2 there was an interface called
Enumeration to visit the elements of Vector. But now we have
two interfaces to visit the elements of Vector. They are
Iterator and ListIterator.
vii) Vector elements can be accessed randomly because it
implements RandomAccess marker interface
viii) Values will be stored in the same order as inserted.
ix) The elements in Vector can be accessed by Enumeration,
Iterator and ListIterator.
ArrayList:
i)ArrayList is a new class used to store multiple objects.
ii)ArrayList uses array data structure internally to store
the elements.
iiiArrayList uses indexing notation to store
values(sequentially).
iv)ArrayList can grow and shrink dynamically.
v)Duplicate values are allowed.
vi)ArrayList is not synchronized.
vii)ArrayList elements can be accessed randomly because it
implements RandomAccess marker interface.
viii)Values will be stored in the same order as inserted.
ix)The elements in ArrayList can be accessed by Iterator and
ListIterator.
