How to iterate multiple arraylist

Question

In my application 2 Arraylists are there:

1) rejectedList  - employees info whose status is rejected
2) acceptedList  - employees info whose staus is accepted 

those 2 Arraylists are added to one mainList and returned.

i need to iterate mainList , seperate those 2 lists and set to new 2 arraylists

    while(rs.next()) {

      UserDTO userDTO = new UserDTO();  
      // getting values from db

      userDTO.setUserKey(UserKey);
      userDTO.setGroupId(bankGroupId);
      userDTO.setDisplayUserId(displayUserId);
      userDTO.setStatus(status);

      if(status.equalsIgnoreCase("Reject")){
        rejectedList.add(UserDTO);
      } else if (status.equalsIgnoreCase("Accept")) {
        acceptedList.add(UserDTO);
      }
    }

  mainList.add(rejectedList;
  mainList.add(acceptedList)
  return mainList;

Answer 1

So really you just want to sort the main list into two sections, based on the accepted/rejected attribute? If this is the case you may want to use a map.
