Replace an object with set(int, Object) method

     

In this section you will learn to replace an object from a particular position specified by a index value. Here is an example that provides the usage of the set(int, object) method in more detail. 

Create a class "VecReplace" with an ArrayList .Populate it with the integer objects using the add(int,object) method. Now replace an object from a particular position specified by a index value using the replace() method.

 

Here is the Code of the Example :

 

VecReplace.java

import java.util.*;
public class VecReplace{
  public static void main(String args[]){
  Vector v = new Vector();
  v.add(0,new Integer(10));
  v.add(1,new Integer(20));
  v.add(2,new Integer(10));
  v.add(3,new Integer(20));
  v.add(4,new Integer(10));
  v.add(5,new Integer(20));
  System.out.println("The actual Vector Size: " + v.size());
  for(int i=0; i < v.size();i ++){
  Integer iw =(Integer) v.get(i);
  System.out.println(iw);
  }
  v.set(2,new Integer(50));
  System.out.println("After removing the element from the 
position 3, Vector Size: " 
+ v.size());
    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 VecReplace.java

C:\roseindia>java VecReplace
The actual Vector Size: 6
10
20
10
20
10
20
After removing the element from the position 3, Vector Size: 6
10
20
50
20
10
20
