lookup this bomb the father than exist the term we use isn't rolled his an exception that's just like a mistake part so let's say under the buffer flower return on trying to read students at xmas dunes dot tech doesn't exist i think al that's an exception well i can do with the exception electrode section so someone gets the exception you got the exception does then i think something then hein when doing the exception you cut it that's important hold on to a different time being okay because it's important right that that says other valuable commodity sigit hold that exception hold that thought so when an exception gets thrown there have to be some notion of catching the exception hopefully and if no one catches the exception your program is going to stop executing cuz if there's no wonder cast exception that exception just going to start to go up all possible functions in your program and say hey is there anyone here to catch me there's no one here to catch me okay your program is done because no one comment and i'm a pretty important thing the cat and that's why i need you to catch it are set up for catching it and article effort but it's important to catch and hold onto of the timing fan how do you actually catch exception or how do you tell the computer i'm going to do something that may involve an exception so you actually need to set it up and let the computer no hey i'm going to do something that may involve an exception the way you say that if you see tried i want you to try something this thing they throw an exception so be prepared but i want you to try it inside here you have your colleague for file access and that's whatever you're doing with the file trying to create a new buffered reader with the file reading in mind one by one or closing a file anytime you're trying to do something involve the file access you need to put it inside this thing called the tried it says hey i'm going to try this out and make your own exception now what happens if it does throw an exception you have something over here where you write trash and what you're going to catch in this case is something called an audio exception because it's an exception that happens when you're trying to do are you know or input-output this dx thing which is actually the exception of several envelope that you actually catch in your hands and then you have some code here which is how to deal with the exception so if you were doing something inside here and some places soon as you get to it says while something bad happened exception it does not execute anymore of the remaining statements inside this block for trial as soon as it gets an exception inside here it says well here is an exception in throws it where are you going to catch a you're going to catch it here which means as soon as an exception gets thrown even in the middle somewhere here the rest of this does not get executed and it comes over here to this code to deal with catching the exception if it gets through all of the code where you say hey i'm going to try something dangerous against ur all that it doesn't throw an exception this code down here is not executed so this co down here is a poorly executed if an exception was thrown what does that actually look like
