Exceptions – very exciting (try/catch block ) part 1 – New Hope

Hello , lovely people. welcome back to more coding than you can keep up with !

We will cover the exciting topic of exceptions.

Now ! pardon my enthusiasm but exceptions can indeed help you not get thrown out of your job.

How, you ask? Have I finally lost my marbles? Yes! , but more importantly exceptions will arise when an exception event occurs.

However, is not because of your perfect program, on the contrary it will be when a problem arises while the program it’s being executed.

Now don’t feel too bad yourself , There are times when exceptions occur and it wasn’t our fault !! ( I know that’s incredible )

But , they may happen when a user has entered an invalid data. A file that needed to be found was not found, or if you are really unlucky the network was lost.

So , if you are like me , and have been playing Pokemon go you are internally telling me how do I catch this pesky exceptions.

Say no more I bring to you the all mighty try/catch block , and the method caller “throws”.

( all code will be available at the bottom of the page with a link to the program inside my GitHub )

For, our example let’s look at a nice array with an index value of 6 .

However, If I want to win a poker game I want to access my favorite lucky number 7 !!

So , I prepare in case something goes wrong , and implement the try and catch block . For this scenario we will be using the ArrayIndexOutOfBoundsException

what nice , compact name am I right ? , anyways if for some mysterious reason something goes wrong we will print . ” We catch an exception “
