The Vector class is contained in the java.util package so we have to import the java.util package using the import statement to use the Vector class in the code. The Vector class was a part of Java 1.0, but in Java 2, the Vector class was rewritten to implement the List interface and thus it became the part of the Java Collection Framework.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. ArrayList uses iterator to traverse the elements.In conclusion, the use of Vector in Java is primarily justified when thread safety is a critical requirement or when working with legacy code that relies on Vector. Additionally, if your application specifically requires support for Enumeration or frequent resizing of the collection, Vector can be a suitable choice.The Vector class implements a growable array of objects.
