I have the below code and I needed to add a try catch to insure proper data, the below doesn't work at all. It prompts for the blower value but if I type in an improper value it still will not "catch" the error?  Please help if possible I am very new to java.

      String test = " ";
                boolean badInput = true;
                    if(race.getClass()== Hotrod.class)
                    {
                          Hotrod h =(Hotrod)race;
                            //test = (getInput("Blower equipped: Y/N"));
                                  
                            if (test.equalsIgnoreCase("y"))
                          {
                            h.setBlower(true);      
                          }// end if
                          else if (test.equalsIgnoreCase("n"))
                          {
                                h.setBlower(false);            
                          } //end else if
                          else
                          {
                                  
                              do{
                                  try
                                  {
                                        test = (getInput("Blower equipped: Y/N"));
                                        if (!test.equalsIgnoreCase("y")|| !test.equalsIgnoreCase("n"))
                                        {
                                        badInput = false;
                                        }
                                  }
                                  
                                  catch (Exception ex)
                                  {
                                        JOptionPane.showMessageDialog(null,test  + "Please enter the proper value","Error",JOptionPane.PLAIN_MESSAGE);
                                  }
                             } while(badInput);
                             }//end else
                    } //end if(race.getClass()== Hotrod.class)

In order for an exception to be caught, the exception first needs to be thrown.
http://docs.oracle.com/javase/tutorial/essential/exceptions/definition.html
In this case, there seems to be no need to use the exception mechanism when you can just check  badInput.
