I'm making a program to demonstrate Exception Handling.
(note: the code was written inside towards out)
The user is prompted to input two values (integers) and then the program will divide those values and output the result.
I then added the "try" and "catch keywords for exception handling-instead of the program shutting down if an error occurs,
the words "you cant do that" will appear
I then added a while loop to allow the user another chance to input usable values. Of course, I made sure to make a termination to the loop as well.
Everything works as expected if the user inputs e.g 8 divided by 0. in that case exception occurse, the user is told "you cant do that", is then prompted to start over and so forth until he gives usable integers. then the program continues to the termination
However, if the user inputs a
String , e.g 9 divided by xyz, then the program goes into an endless loop
My question is:
1) why does a String cause an endless loop ( I have a theory)
2)why does the loop occur
as soon as I put in an incorrect value- is the while loop somehow in extant? somehow always waiting? (hard to picture it)
3) lastly, what would be the correct code to handle and exception caused by a String (as opposed to being caused by impossible to execute math)
here is the program
(and thank you so much for helping)
