I have an object created from Java class IntegerStringConverter that trows exceptions like java.lang.NumberFormatException, is it possible to catch or suppress them without try ... catch block?

Consider taking advantage of String#toIntOrNull instead

[kingsley]

Then you won’t have to deal with any exception/catching

@kingsley thanks, for these days I've tried it. And finally stayed with setting custom TextFormatter (and overriding TFX functions, and writing custom TableCell) to prevent this exception ever happen. But I could not find how to push back those exceptions without user interaction. I.e. when such exception arises, and we see the call stack, exiting this exception dialog, program returns to the moment before the exception. So I supposed that it can be done automatically and silently

[kingsley]

not sure I understand the dialog you’re describing

do you mean the app is crashing? in that case, try/catch will silence the crash.
However, you can just use the method I mentioned earlier, so you only have to check for null instead of catching exceptions which is much more expensive

This dialog. I would like to know, how to prevent it showing (and suppress error stack in stdout). It's kinda advanced exception handling

And without any try ... catch, and without avoiding this error changing logic. I.e. I want this error to happen, but silently
