Question: Can anyone tell me why the Java Vector class is called a "Vector"?
I come from the engineering world, so I am trying to make some sense out of the
name.
Answer: "Vector" is a common name for an array of one dimension. I think that it
was designed to be accessed in only one direction - from start to end. Of
course, you can write code to iterate backwards...
But the enumeration it goes you don't have a getPrev() method, only a getNext():
for (Enumeration e = v.elements() ; e.hasMoreElements()  {
System.out.println(e.nextElement());
}
So a Vector has dimension (number of elements) and direction (in terms of
access). Are you agree?
