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...
Vectorsare synchronized. Any method that touches theVector's contents is thread safe.ArrayList, on the other hand, is unsynchronized, making them, therefore, not thread safe. With that difference in mind, using synchronization will incur a performance hit. So if you don't need a thread-safe ...
ArrayList and Vector are similar classes only difference is Vector has all method synchronized. Both class simple terms can be considered as a growable array. ArrayList should be used in an application when we need to search objects from the list based on the index. ArrayList performance degrades...
vector arraylist list collections Basic Q21.What is the quickest way to find count of duplicate elements in an arraylist, without using iteration or loops ?Core Java Ans. We can copy the elements to a Set and then find the difference of count between ArrayList and Set. As Set don...
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 ...
Implements all optional list operations, and permits all elements, including null . In addition to implementing the List interface, this class provides methods to manipulate the size of the array that is used internally to store the list. (This class is roughly equivalent to Vector , except ...

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...
ArrayList implements List, such as LinkedList or Vector. ArrayList is a good alternative traditional array. 19th Mar 2017, 12:25 PM Sergey L. 0 my biggest difference (why I choose one over the other) is what I'm doing. ArrayList can change in size. so if i am using it to store ...
