Thanks a lot for all the information. 1 more question, after create a new exception class then to use it let's say I have to define something like: Then use it:

[SpontaneousCombustionException signal] on: SpontaneousCombustionException do: [:ex | Transcript show: 'Explosion detected'; cr]

My question is where do I write this code? Is it in one of my method for example I create spontaneousCombustionSignal method, and I write this code there?

Create an exception class:

Exception subclass: #SpontaneousCombustionException instanceVariableNames: '' classVariableNames: '' poolDictionaries: '' category: 'Heat'.

Then use it:

[SpontaneousCombustionException signal] on: SpontaneousCombustionException do: [:ex | Transcript show: 'Explosion detected'; cr]
