问题 I am trying to find out the best way of handling exceptions, I have a number of layers to my application and started to use a return type of BOOL i.e. if it fails then return False and if it succeeds return True.. This works great in methods like SaveMyRecord(somerecord); as i am passing in values and don't require anything returned so i can use the return type of bool to indicate if it succeeds or not. But then it got me thinking that things like GetMyRecord() actually returns type of

问题 I'd like to use to a custom exception to have a user-friendly message come up when an exception of any sort takes place. What's a good straightforward way of doing this? Are there any extra precautions I should take to avoid interfering with Swing's EDT? 回答1: Exception Translation: It's a good idea to not pollute your application with messages that have no meaning to the end user, but instead create meaningful Exceptions and messages that will translate the exception/error that happened
