What are the characteristics of vectors in Java?

In Java, Vector is a dynamic array that implements the List interface, and it has the following characteristics:

1. Dynamic resizing: Vector’s capacity automatically increases as needed, increasing capacity to accommodate more elements when the number of elements exceeds the current capacity.
2. Thread safety: Vector is thread-safe, meaning that multiple threads can access and modify the contents of Vector simultaneously. This is achieved by adding the synchronized keyword to each method.
3. Vector can store elements of any type, including objects of wrapper classes for primitive types.
4. Orderliness: The elements in a Vector are stored in the order of insertion, allowing for access and modification based on index position.
5. Support random access: Because elements in Vector are stored in index order, it is possible to quickly access and modify elements by index.
6. Vector offers various methods for traversing and searching elements, such as utilizing iterators or using the contains() method for element searching.

It is important to note that because Vector is thread-safe, it may be slightly slower in performance compared to non-thread-safe collection classes like ArrayList. If thread safety is not required, it is recommended to use ArrayList.
