URGENT!!!-how to split id (|)

hi,

 I have a delete.jsp that receives ids such as user1|user2|user3

String[] id = request.getParameterValues("id") ;

    for(int i=0; i < id.length; i++)

    {

out.println(id[i]);

      String Query = "delete FROM volunteer where username='"+id[i]+"'";
      int status= statement.executeUpdate(Query);



 

  if(status != 0)
  {
   out.println("Entry successfully deleted.");
  }
 
  else
  {
  out.println("Deletion not successful");
  }

}

}


My problem is id[0] is user1|user2|user3


i need to split it into

id[0]=user1
id[1]=user2
id[2]=user3 and etc

i mean discard | and put into array.


Pls help , i need it urgently

Hi!

It's quite simple when using StringTokenizer:

import java.util.*;
...
String id = request.getParameter("id");
StringTokenizer parser = new StringTokenizer(id,"|");
while (parser.hasMoreTokens()) {
   String query = "DELETE FROM volunteer WHERE username = '" + parser.nextToken() + "'";
   ...
}

Good luck!

well first I am not sure why you are getting id[0] as user1|user2 format but.. this is what you can do..

StringTokenizer st = new StringTokenizer(id[0],"|");
String[] ar = new String[st.countTokens()];
int i=0;
while(st.hasMoreTokens())
{
ar[i]=st.nextToken();
i++
}
This will put all the stuff in String array ar.
Hope this helps
Regards

You can use StringTokenizer for this.

Something like this

String ids="user1|user2|user3";
StringTokenizer tokenizer = new StringTokenizer(ids,"|");

String[] ids = new String[tokenizer.countTokens()];
int i = 0;
for (int i = 0; i< tokenizer.countTokens(); i++)
  ids[i] = tokenizer.nextToken();
}
