Retrieve the dynamic
capacity of a list
In this section you will learn
to get the capacity of a list i.e. retrieving the number of objects contained in
it. Here is an example that provides the
usage of the size() method in more detail.
Create a class "VecSize" with a Vector. Populate
it with the integer objects using add(object) method. Now
retrieve the total number of objects contained in it using the
size() method.
Here is the Code of the Example :
VecSize.java:
import java.util.*;
public class VecSize{
public static void main(String argv[]){
Vector v = new Vector();
v.add(new Integer(1));
v.add(new Integer(2));
v.add(new Integer(3));
v.add(new Integer(4));
System.out.println("Vector Size: " + v.Size());
}
}

Here is the Output of the Example :
| C:\roseindia>javac VecSize.java
C:\roseindia>java VecSize
Vector Size: 4 |
