Java Mysql Integrity Constraint Violation Exception -

-

my swing applications throws few exceptions. tried catch integrity constraint violation exception , display message "duplicate id". when happened, without catching here: catch(mysqlintegrityconstraintviolationexception ex) goes catch (sqlexception ex). want is, catch integrity violation exception , display user friendly message instead of technical message comes ex.getmessage(). how do this? 

              shippmenttransfer shiptrns = new shippmenttransfer(shipid, gin, issuedate, tostore, itemname, qty, driver, vehicle);                     int res = shipmenttanscontroller.addshipgin(shiptrns);                     if (res > 0) {                           joptionpane.showmessagedialog(null, "record added");                           resetall();                     }               } catch (dataintegrityviolationexception ex) {                     joptionpane.showmessagedialog(null, "duplicate id");                } catch (classnotfoundexception ex) {                     joptionpane.showmessagedialog(null, ex.getmessage());               }                catch (sqlexception ex) {                     joptionpane.showmessagedialog(null, ex.gets);               }         }

in order catch specific sqlexception, need compare against sql state using getsqlstate() method. ex: sql state 23 data integrity violation. 

 catch (sqlexception ex) {                     if (ex.getsqlstate().startswith("23")) {                           joptionpane.showmessagedialog(null, "duplicate");                     }                }

android - getbluetoothservice() called with no bluetoothmanagercallback -

i getting getbluetoothservice() called no bluetoothmanagercallback error in android application. i have no idea causing or bluetooth manager callbacks. can give me idea of causing problem or start looking. by reading android source code, seems warning cannot about. source code shows if call bluetoothsocket#connect(); then call bluetoothadapter.getdefaultadapter().getbluetoothservice(null); the key here, null parameter passes in above line. due this, there no callback, , bluetoothsocket class throw out warning. since warning, not think need it. https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/bluetooth/bluetoothsocket.java line 306 https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/bluetooth/bluetoothadapter.java line 1610
