- Import the following classes:
- Invoke getContents() on a PersistentObject.
- To convert to your desired format, perform an explicit cast on the object that PersistentObject.getContents()returns.
synchronized(store) { String[] currentinfo = (String[])store.getContents(); if(currentinfo == null) { Dialog.alert(_resources.getString(APP_ERROR)); } else { currentusernamefield.setText(currentinfo[0]); currentpasswordfield.setText(currentinfo[1]); } }
