Vector elementAt() Java example

The elements() method of the Vector class is used to retrieve an enumeration of the elements that were added to the vector. A while loop is then used to cycle through and print the elements contained in the enumeration. The hasMoreElements() method is used to determine whether the enumeration contains more elements. If it does, the nextElement() method is used to retrieve the object for printing.

The removeElement() of the Vector class is used to remove the vector element The for loop indexes each element in the vector using the elementAt() method.
