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.

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
