Unlike the new collection implementations, {@code Vector} is synchronized. Field Summary. protected int, capacityIncrement. The amount by which the capacity of
A vector can be viewed as similar to another dynamic array data structure, ArrayList except for the two below differences: The vector is synchronized i.e. all the methods in Vector are marked ‘synchronized’ and thus once a method is invoked, the same method cannot be … 2013-12-14 Vector is Synchronized means thread safe, only 1 thread can access so its very slow compared to ArrayList, because in our real time projects we should not require synchronized methods always. What am saying is always try to use ArrayList rather Vector if its not required any Synchronization in your requirements, even if so you know how to make ArrayList as synchronized right (just like above). Difference between ArrayList and Vector is the most common Core Java Interview question you will come across in Collection .Arraylist vs Vector in Java 1.

if you open Vector source code you will see all the method are taged with synchronize keyword which say the access to that methods are controlled or synchronized. which makes Vector a thread safe. when multiple threads are accesing this Vector object, the object wil be synchronized. Vector is synchronized. Vector contains many legacy methods that are not part of the collections framework.
As Vector is synchronized, it operates slower than ArrayList. Enumeration/Iterator, ArrayList uses Iterator interface to traverse the objects stored in ArrayList. Vector
As of the Java 2 platform v1.2, this class was retrofitted to implement the {@link List} interface, making it a member of the Java Collections Framework. Unlike the new collection implementations, {@code Vector} is synchronized. public synchronized void add (E value) Add objects in VectorCustom. public E get (int index) Method returns element on specific index.
But Vector is synchronized, due to this reason, it is rarly used in the non-thread application. It also lead to poor performance. The Vector is a class in the java.util
which makes Vector a thread safe. when multiple threads are accesing this Vector object, the object wil be synchronized. Vector is synchronized. Vector contains many legacy methods that are not part of the collections framework. Vector proves to be very useful if you don't know the size of the array in advance or you just need one that can change sizes over the lifetime of a program. Following is the list of constructors provided by the vector class. As of the Java 2 platform v1.2, this class was retrofitted to implement the List interface, making it a member of the Java Collections Framework.

Both (ArrayList and Vectors) use dynamically resizable arrays as their internal data structure. Whereas both ArrayList and Linked List are non synchronized. But Jul 18, 2007 Vector vs. Collections.synchronizedList.
