difference between synchronized list and vector

can any one tell me difference between synchronized list and vector

Hi Raja

Difference between Vector and List is

Vector are Thread Safe It means Only one Thread can accec Vector SO it can Hit the Performance.

Whereas List are not Thread Safe so as many thread acess the same at same time.

So High Performance is achived.

So If need to understand our requirement Whther er need thred safe and non thred safe model to store our objects.

Syncronized ArrayList and vector both are syncronized. But probably parformance of ArrayList is better than vector.

Vector implements the List interface, so Vector is a synchronized List.

On what do you base that ? Both Vector and ArrayList are backed by arrays, so i would expect performance to be pretty similar. But I would be happy to be corrected on this if you have any figures to support your statement.

This is helpful...
