Settings in MIDP

Question

Hello
I'm trying to build a settings class for mobile devices, but the problem is that I found only one possibillity to save settings, and that's record stores. Record store's draw back is that I shall read my settings with record's associated id, so I must remember the id for every settings. I dont understand how can i do this, anyone can help? thanks :)

Answer 1

you think that it is urgent but it is not so urgent !!
you are not the only one...
so, create a custom class Settings
* Exemple to show that it s possible to store all the parameters settings
* in a java class called <code>Settings</code>. This class contains
* the login, the password, the host ...
* @author <your_name>
public class Settings{
  // contains all the stuff needed for your connexion
  private String login;
  private String ...
  public Settings(...){
    // fillin the class
}and in your MIDlet..
RecordStore rs = null;
Settings settings=null;
try {
  rs = RecordStore.openRecordStore( rsName, false );
  treateRS(rs);// treate the RecordStore
} catch( RecordStoreException e ){
  // print the exception
} finally {
  try {
    rs.closeRecordStore();
  } catch( RecordStoreException e ){
    // Ignore this exception
public void treateRS(RecordStore record){
  // get the Settings object, analyse it,etc ...
}is it clearer?
