If you are executing multiple statements in a row that can throw an exception should you use two try-catch blocks or one and handle the exception from each line separably.

Option #1

code:

try{
    onething
}
catch{...}

try{
    anotherthing
}
catch{...}


Or option #1

code:

try{
    onething
    anothetring
}
catch onething's exception type{

}
catch anotherthing's exception type{

}

This largely depends if you want "anotherthing" to be attempted or not, given that "onething" is throwing an exception.

There's no right answer. A lot of it comes down to how it "feels."

For me, the question is whether onething and anotherthing are related. If so, then they should probably be in the same try block.

Is it recommended to have the exception type even if you just abort and don't use it?

It is recommended to have the exception type so that you are catching only the expected exceptions. Should things truly go wrong, you'd want to know about this.
