What Is The Difference Between Vector And Arraylist In Java?

Vector and ArrayList are very similar. Both of them represent a 'growable array', where you access to the elements in it through an index.

ArrayList it's part of the Java Collection Framework, and has been added with version 1.2, while Vector it's an object that is present since the first version of the JDK. Vector, anyway, has been retrofitted to implement the List interface.

The main difference is that Vector is a synchronized object, while ArrayList is not.

1. Arraylist is not synchronized while vector is.
2. Arraylist has no default size while vector has a default size of 10.
3. We can specify the increment size with the vector and with array list we cannot.
