1)Synchronization: ArrayList is non-synchronized which means multiple threads can work on ArrayList at the same time. For e.g. if one thread is performing an add operation on ArrayList, there can be an another thread performing remove operation on ArrayList at the same time in a multithreaded ...
Synchronization:Vector issynchronized, which means only one thread at a time can access the code, while ArrayList isnot synchronized, which means multiple threads can work on ArrayList at the same time. For example, if one thread is performing an add operation, then there can be another thread...
Vector is synchronized while ArrayList is not synchronized .Synchronization and thread safe means at a time only one thread can access the code .In Vector class all the methods are synchronized .Thats why the Vector object is already synchronized when it is created . 2. Performance Vector is sl...

Q6.What is meant by "Vector is synchronized and ArrayList isn't " ?Core Java Ans. It means that only 1 thread can access have access to Vector at a time and no parallel access is allowed whereas Array List allows parallel access by multiple threads. ...
Learn to clear arraylist or empty an arraylist in Java. Clearing a list means to remove all elements from the list. Difference between clear and removeAll.
ArrayList maintains the insertion order, which means the elements appear in the same order in which they are inserted. ArrayList is non synchronized. However you can make itsynchronized. Hierarchy of ArrayList class in Java ArrayList class implements List interface and List interface extends Collection...
2. The second difference between them comes from the fact how their iterator behave. The Iterator returned from synchronized ArrayList is a fail-fast but the iterator returned by CopyOnWriteArrayList is a fail-safe iterator. This means it will not throwConcurrentModificationExceptioneven when the list...
The synchronization is the most significant difference between theArrayListand Vectors. Among them, theVectoris synchronized, which means only one thread can access it at a time. On the other hand, theArrayListis not synchronized; multiple threads can access it simultaneously. ...
The primary difference between anArrayListandCopyOnWriteArrayListis that aCopyOnWriteArrayListis synchronized, whereas anArrayListis not synchronized. This means that only a single thread can operate on aCopyOnWriteArrayListinstance at a time and other threads need to wait until that lock is released, where...
