vector and array list

[vishnu hiranamayee]

Hi
Both vector and arraylist are growable arrays and the differnece is vector is synchronized and arraylist is not synchronized.
How is synchronization done in vectors.

In the same way you synchronize your classes.
The set() method in Vector looks like this

public synchronized Object set(int index, Object element) {
}

Where as the set() method in ArrayList reads

public Object set(int index, Object element) {
}

Got the difference?

[vishnu hiranamayee]

public synchronized Object set(int index, Object element) {}

But in the API of vectors only
Object set(int index, Object element)
is given .

if we give
public synchronized Object set(int index, Object element) {}
then arraylist will also be synchronized?
Then what is the differnece between vector and arraylist?

Yes . Java Collections Framework remedies these problems and offers a number of advantages over using no framework or using the Vector and Hashtable
