B4J Library [B4x] Throwables library

This is a simple b4xlib library that just allows throwing an IllegalArgumentException or a NumberFormatException.

Sometimes a Toast or Dialog is not enough of an alert that something is going to break if the data passed is incorrect, especially in libraries.

Compatible with B4a and B4j.

Usage:

B4X:
Dim TH as Throwables
TH.Initialize
TH.Throw(Throwables_Static.NewIllegalArgumentException("Invalid Argument"))

or

TH.Throw(Throwables_Static.NewNumberFormatException("Invalid Number"))

The exceptions can be caught in the normal way with a try .. catch block.

Version 1

Sorry, one Dim jFX slipped through and would obviously break the B4a implementation.

Please download it again now.
