CopyOnWriteArrayList and ArrayList in Java.
we have seen What is CopyOnWriteArrayList in Java and How it achieves thread-safety by creating a separate copy of List for each writes operation.
Now let's see Some difference between ArrayList and CopyOnWriteArrayList in Java, which is another implementation of List interface :
1) First and foremost difference between CopyOnWriteArrayList and ArrayList in Java is that CopyOnWriteArrayList is a thread-safe collection while ArrayList is not thread-safe and can not be used in the multi-threaded environment.
2) The second difference between ArrayList and CopyOnWriteArrayList is that Iterator of ArrayList is fail-fast and throw ConcurrentModificationException once detect any modification in List once iteration begins but Iterator of CopyOnWriteArrayList is fail-safe and doesn't throw ConcurrentModificationException.
3) The third difference between CopyOnWriteArrayList vs ArrayList is that Iterator of former doesn't support remove operation while Iterator of later supports remove() operation. If you want to learn more about collections, I suggest you go through Complete Java MasterClass, one of the best Java course on Udemy.
