what is the difference between ArrayList and Vector
Answer Posted / vikas
1. Vector is synchronized while ArrayList is not.
2. Vector has default size is 10 while ArrayList has 10(Look
Java Class).
3. We can specify increment size with Vector.
4. If we use ensureCapacity(int minCapacity) to set the
default increment size then remember following things:
a. Vector v = new Vector();
b. V.capacity(); === output will be 10
c. If you try to set v.ensureCapacity(5),then
d. V.capacity(); ===10
e. If you try to set v.ensureCapacity( >20), then
f. V.capacity();===20 and
g. If you try to set v.ensureCapacity(21), then
h. V.capacity();===21, It clears that if set capacity over
20 then it will be set otherwise no.
