Question

let’s say methodA and methodB will both throw a couple of types of exceptions, and some exceptions are of the same type, some are not, so what’s the best practice to handle this?

style A:

void foo()
    {
        try
        {
            methodA();
        }
        catch (exceptionTypeA)
        {
            handleA;
        }

        try
        {
            methodB();
        }
        catch (exceptionB)
        {
            handleB;
        }
    }

style B:

void foo()
    {
        try
        {
            methodA();
            methodB();
        }
        catch (exceptionTypeA)
        {
            handleA;
        }
        catch (exceptionB)
        {
            handleB;
        }
    }

Answer 1

Neither is “better”; they’re simply different. Depending upon what you do in your catch block, the first option will allow methodB to execute even if methodA throws an exception of type exceptionTypeA, while the second block requires that methodA succeed in order for methodB to be called.
