while Vector is synchronized. This means if one thread is working on Vector, no other thread can get a hold of it. Unlike ArrayList, only one thread can perform an operation on vector at a time. 2)Resize:Both ArrayList and Vector can grow and shrink dynamically to maintain the optimal us...
Difference between Vector and Arraylist is the most common Core Java Interview question you will come across in Collection . This question is mostly used as a start up question by the Interviewers before testing deep roots of the Collection . Vector , ArrayList classes are implemented using dynamic...
11.1. Difference between ArrayList and Array In Java, arrays and arraylist, both, are used to store collections of elements as an ordered collection and provide index-based access to the elements. Still there are few differences as discussed: Arrays are fixed size data structures and cannot be ...
A rather significant difference is that the Vector class has all methods synchronized. The advantage of the Vector in our problem is that it can be initialized with any number of elements. Besides this, all its elements will be null by default: @Test public void whenInitializingListWithVector_...

and Vector. They share the common methods of the List interface, so it doesn't matter if the object is instantiated as ArrayList or LinkedList, it will act as a List either way, but maybe the internal mechanics will be different, and the developer can choose the type that better fits the...
