Remove a value with remove() method
In this section you will learn
to remove an object from a particular position specified by a index
value. Here is an example that provides the
usage of the remove() method in more detail.
Create a class "VecRemove" with an vector.
Populate
it with the integer objects using add(int,object) method. Now
remove an object from a particular position specified by a index value
using the remove() method. Specify the index position from where you want
to remove an object.
Here is the Code of the Example :
VecRemove.java :
import java.util.*;
public class VecRemove{
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));
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.remove(3);
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);
}
}
}

The Output Of The Example is as shown:
| C:\roseindia>javac VecRemove.java
C:\roseindia>java VecRemove
The actual Vector Size: 6
10
20
30
40
50
60
After removing the element from the position 3, Vector Size: 5
10
20
30
50
60 |
