Get Sub List of Java Vector Example

  Get Sub List of Java Vector Example
  This Java Example shows how to get sub list of java Vector using subList
  method by providing start and end index.

      Sub List returned by subList method is backed by original Vector. So any
      changes made to sub list will also be REFLECTED in the original Vector.

  }
 
}
/*
Output would be
Sub list contains :
2
3
2 is removed from sub list
After removing 2 from sub list, original Vector contains :
1
3
4
5
