Vector

[Ricardo Polero]

Hi, all
When compile and run this:
import java.util.*;
public class Q5 {
public static void main (String[] args) {
Q5 obj = new Q5();
Vector vectorDemo = new Vector(10);
Vector vectorDemo1 = new Vector();
System.out.print(vectorDemo.size() + ",");
System.out.print(vectorDemo.capacity() + ",");
System.out.print(vectorDemo1.size() + ",");
System.out.print(vectorDemo1.capacity());
}
}
the capacity of vetordemo1 give 10 ?
10 is the default capacity ? Some comments ?
Thx in adv

The initial size of a Vector is 10 (check out the default constructor in the API). Although I can't find the reference, I believe the initial capacity is the same as the size unless you use one of the other constructors to explicitly set the capacity.
someone correct me if I'm wrong

You've pretty much got it Dave. Just to add, a vector is at least as big as it's capacity and usually bigger. Since you used the constructor Vector(int initialCapacity) The capacity comes up as 10, as Dave pointed out.
