Delete and modify orgs from Load from File

Question

Hi,
I created my organizations with the Configure > Import File option, but how can i delete or modify organizations in a same way.
Thanks,

Answer 1

In that case Do i need to write the entire contents of my file to a hash table(sumthng like this) and modify the Second row in my case with the new values..
is it possible??I would have done like this (though there maybe better methods)
1- create a class representing the record.
class Record{
      String field1;
      String field2;
      String field3;
      // and so on....
      //setters
      public void setFeild1(String str){
          field1=str;
      // and so on....
      //getters
      public String getFeild1(){
          field1=str;
      // and so on....
      public String toString(){
           return(field1+"||"+field2+"||"+field3);
}//end class2- then create an ArrayList meant to have objects of this class (Generics).
3- read from the file , create a new Record Object and add that to the ArrayList
4- perform operations on the ArrayList (you can add new records, and delete record, update......)
5- write the record back to file using 'toString()' method.
is there ne sample code available for thisdon't know, but you rarely get full code on forums.....outline given can be followed
Thanks!
Edit: It appears that 'r035198x' and me have the same point. This shows that this methodology is almost a standard way( if we ignore the Random access files.....)
