It allows us to create resizeable arrays (just like ArrayList). You can use any primitive type elements like- int, char, etc. It is found in java.util package. The Vector class implements the List interface and is a child class of the AbstractList class. The capacity of the Vector class is dynamic in nature, which means you can shrink or ...In Java8 Vector's source, there is no depracated notice. There is the following comment in the header : Unlike the new collection implementations, {@code Vector} is synchronized. If a thread-safe implementation is not needed, it is recommended to use {@link ArrayList} in place of {@code Vector}.The java.util.Vector methods are all synchronized. So using it from multiple threads is "safe". You only need to synchronize if you need a read-evaluate-write process to be atomic. Synchronizing your own methods does not necessarily make your code thread-safe for those scenarios. If the shared state is the Vector …Java is a popular programming language widely used for developing a variety of applications and software.
