Sorting exceptions into two categories (namely “unchecked” and  “checked” exceptions) can significantly change how we handle exceptions  within our program. 

Checked exceptions are exceptions that occur at compile-time. These  exceptions occur due to factors or events that are outside of our  program’s immediate control–such as network issues, Input/Output device  issues, files not being found when called, etc. Checked exceptions must  either be dealt with inside of the method in which they are thrown, or  else they must be passed up to an exception handler in higher-up method  (by adding a “throws” clause in the method’s argument parameter).

Because of this ability to pass the exception to another method,  these types of exceptions have the potential to be ignored or  “swallowed” (as some of the material has dubbed), although this is not  recommended of course. These exceptions should be dealt with in some way  within our program wherever absolutely possible utilizing try-catch  blocks or try-catch-finally blocks.

Unchecked exceptions are exceptions that occur at run-time. These  consist of exceptions that deal with issues within our actual program  code (or possible issues due to the user’s interaction with our code).  Examples of these would be trying to access an element outside of a  specified array, attempting to divide a number by 0, or a user  attempting to input a letter or string into an input box designed to  accept an integer. 

These types of exceptions are dealt with on an “as-needed” basis, one  might could say, as they attempt to catch specific errors that can  spring up from the execution of buggy code. Thoroughly testing our code  and being aware of the different types of exceptions that could occur  within our code (and then properly handling them) can keep our code  functioning smoothly and efficiently. 

When it comes to which method I would prefer:

The geeksforgeeks.com website reads that throwing checked exceptions  may be a better option if the user has a decent amount of control over  recovering from the exceptions, and if not, unchecked exceptions are  better used. It also appears that checked exceptions can allow for more  robust code, although (as stated earlier), this does give programmers  the opportunity to pass the buck and not deal with certain exceptions  simply because they do not want to be thorough. But I also found from my  research that some languages (such as C#) do not have checked  exceptions, and that language appears to work well without them.

Reflecting upon my researching of this subject, (and my limited  experience utilizing exceptions in my own code in my last course), I  feel as though I would be more inclined to utilize unchecked exceptions,  when possible. I think it makes more sense to be able to address the  exceptions as needed rather than “covering the entire code with ‘throws’  clauses” as the infoworld.com website puts it. Although, I am totally  new to this realm, so I’m sure I’ll learn more as I go!

Thanks for reading, all and best of wishes in the module!
