Insert an element with the add(int, Object) method

     

In this section you will learn to insert an element at the specified position using the add(int, Object) method. Here is an example that provides the usage of the add(int, Object) method in more detail.

Create a class "VecAdd". Take a vector and populate it with the integer values using the add(int,object) method on a specified position.

Here is the Code of the Example :

VecAdd.java

import java.util.*;
public class VecAdd{
  public static void main(String argv[]){
  Vector v = new Vector();
  v.add(0,new Integer(10));
  v.add(1,new Integer(20));
  v.add(2,new Integer(30));
  v.add(3,new Integer(40));
    v.add(4,new Integer(50));
  v.add(5,new Integer(60));

  for(int i=0; i < v.size();i ++){
  Integer iw =(Integer) v.get(i);
  System.out.println(iw);
  }
  }
}

 Here is the Output of the Example :

C:\roseindia>javac VecAdd.java

C:\roseindia>java VecAdd
10
20
30
40
50
60
