Note that as of the Java 2 platform v1.2, Vector class was retrofitted to implement the List interface. If a thread-safe implementation is not needed, it is recommended to use ArrayList in place of Vector. Happy Learning !! Read More: ArrayList Java Docs Vector Java Docs 51. You should normally use ArrayList - it offers better performance. Vector has just one "advantage" - it is synchronised for concurrent modification. But it turns out in practice that this feature isn't very useful because Vector synchronises at the level of each individual operation. If you are writing concurrent code, you typically need to ...Free font-viewing program Opcion allows you to scroll through all of your fonts for real time rendering of sample text. Free font-viewing program Opcion allows you to scroll throug...Simply specify the type while instantiating the vector: public Vector <concreteType> objVector = new Vector <concreteType>(50); Using generics you can specify a hierarchy based type restriction: class yourClass<TYPE extends SomeType>{ public yourClass(){ public Vector <TYPE> objVector = new Vector <TYPE>(50); } }Vector is slow compared to ArrayList. Vector operations gives poor performance as they are thread-safe, the thread which works on Vector gets a lock on it which makes other thread wait till the lock is released. ArrayList is not a legacy class. Vector is a legacy class.
