>>42Marking all functions with
throws is better than no markings at all, but it still makes error handling sloppy and you get all the same problems as usual with exceptions. Unless you wrap each line in your function with a try catch block, you don't know where the exception was thrown from, which can be very important information for the clean up. You can guess by the type of the exception thrown, but exception types are subject to change. And you never would wrap each line with a try catch block because it would be so verbose. It motivates you to deal with errors in a sloppy and unreliable way. Error codes make you ingrain error handling into the natural behavior of the function. Error handling and functionality mix. This is the perspective you should have if you want to keep correct behavior in all cases.
Though Java has
finally at least.
