How to get Vector size or Vector length in Java?

The size method of the Vector class returns the number of elements contained in this vector object.

It returns an int number that is equal to the number of elements currently stored in this vector object. It returns 0 if the vector does not have any elements.


We can also use the size method to check if the Vector object is empty or not. To do that, we need to compare the return value of the size method with 0. If it is equal to 0 then the vector is empty, otherwise, it is not.
