Sometimes, I see
try {
} catch(Throwable e) {
}
And sometimes
try {
} catch(Exception e) {
}
What is the difference?
By catching Throwable it includes things that subclass Error. You should generally not do that, except perhaps at the very highest "catch all" level of a thread where you want to log or otherwise handle absolutely everything that can go wrong. It would be more typical in a framework type application (for example an application server or a testing framework) where it can be running unknown code and should not be affected by anything that goes wrong with that code, as much as possible.
